This utility was designed to be an API platform used initially to validate CycloneDX or SPDX Software Bills-of-Materials (BOMs) against versioned JSON schemas, as published by their respective communities, as well as customized schema variants provided by companies or organizations that have stricter BOM compliance requirements.
The utility has now grown to include a rich set of commands, listed below, that can be used for create filtered reports in many formats (e.g., csv, md) using the utility's powerful, SQL-like query capability. These commands can extract data from BOMs that enables verification of information supporting BOM use cases or any custom security and compliance requirements.
The utility supports the following BOM-related commands:
-
- list produce listings or summarized reports of license data contained in a BOM along with license "usage policy" determinations using the policies declared in the
license.jsonfile. - policy - lists software and data license information and associated license usage policies as defined in the configurable
license.jsonfile.
- list produce listings or summarized reports of license data contained in a BOM along with license "usage policy" determinations using the policies declared in the
-
query produce data listings or custom reports from BOM data using SQL-style query statements (i.e.,
--select <data fields> --from <BOM object> --where <field=regex>). -
resource produce filterable listings or summarized reports of resources, including components and services, from BOM data.
-
schema lists the "built-in" set of schema formats, versions and variants supported by the
validationcommand.- Customized JSON schemas can also be permanently configured as named schema "variants" within the utility's configuration file (see the
schemacommand's adding schemas section).
- Customized JSON schemas can also be permanently configured as named schema "variants" within the utility's configuration file (see the
-
validate enables validation of SBOMs against their declared format (e.g., SPDX, CycloneDX) and version (e.g., "2.2", "1.4", etc.) using their JSON schemas.
- Derivative, "customized" schemas can be used for verification using the
--variantflag (e.g., industry or company-specific schemas). - You can override an BOM's declared BOM version using the
--forceflag (e.g., verify a BOM against a newer specification version).
- Derivative, "customized" schemas can be used for verification using the
-
vulnerability produce filterable listings or summarized reports of vulnerabilities from BOM data (i.e., CycloneDX Vulnerability Exploitability eXchange (VEX)) data or independently stored CycloneDX Vulnerability Disclosure Report (VDR) data.
Experimental commands:
Feedback and helpful commits appreciated on the following commands which will be moved to non-experimental after two point releases:
-
diff : Shows the delta between two similar BOM versions in
-
trim provide the ability to remove JSON information, by field key and limited query syntax, from the input JSON BOM document.

Download and decompress the correct archive file (i.e., .tar for Unix/Linux systems and .zip for Windows) for your target system's architecture and operating system from the releases page within this repository.
The archive will contain the following files:
sbom-utility- binary executable. This is all most need for non-customized configurations.config.json(optional) - copy of the default schema configuration file for optional customization (to be passed on the command line)license.json(optional) - copy of the default license policy configuration file for optional customization (to be passed on the command line)custom.json(experimental) - custom validation configuration fileLICENSE- the software license for the utility (i.e. Apache 2)sbom-utility-<version>.sbom.json- a simple Software Bill-of-Materials (SBOM) for the utility
For convenience, the default config.json and optional license.json configuration files have been embedded in the executable and used if none are provided on the command line using the --config-schema or --config-license flags respectively.
When providing configuration files using command line flags, the executable attempts to load them from the same path where the executable is run from. If you choose to keep them in a different directory, you will have to supply their location relative to the executable along with the filename.
On MacOS, the utility is not a registered Apple application and may warn you that it cannot open it the first time. If so, you will need to explicitly permit the executable to be "opened" on your system acknowledging it trusted. This process is initiated from the Finder application by using ctrl-click on the executable file and agreeing using the "Open" button.
This section provides detailed descriptions of all commands, their flags and examples. First we will cover how all commands generate consistent exit codes and describe some of the persistent flags supported by most commands.
For convenience, links to each command's section are here:
All commands return a numeric exit code (i.e., a POSIX exit code) for use in automated processing where 0 indicates success and a non-zero value indicates failure of some kind designated by the number.
The SBOM Utility always returns one of these 3 codes to accommodate logic in BASH (shell) scripting:
0= no error (valid)1= application error2= validation error
This example uses the schema list command to verify its exit code:
./sbom-utility schema listverify the exit code:
echo $?which returns 0 (zero) or "no error":
0This section describes some of the important command line flags that apply to most of the utility's commands.
- format flag: with
--format - indent flag: with
--indent - input flag: with
--inputor-i - output flag: with
--outputor-o - quiet flag: with
--quietor-q - where flag: with

All list subcommands support the --format flag with the following values:
txt: text (tabbed tables)csv: Comma Separated Value (CSV), e.g., for spreadsheetsmd: Markdown, e.g., for GitHub
Some commands, which can output lists of JSON objects, also support JSON format using the json value.
This example uses the --format flag on the schema command to output in markdown:

All list subcommands and the validate command support the --input-file <filename> flag (or its short-form -i <filename>) to declare file contents (i.e., BOM data) the commands will read and operate on.
All commands that support the input flag can also accept data from standard input or stdin by using the - (dash) character as the value instead of a filename.

All commands support the --quiet flag. By default, the utility outputs informational (INFO), warning (WARNING) and error (ERROR) text along with the actual command results to stdout. If you wish to only see the command results (JSON) or report (tables) you can run any command in "quiet mode" by simply supplying the --quiet or its short-form -q flag.
This example shows the --quiet flag being used on the schema command to turn off or "quiet" any informational output so that only the result table is displayed.

It can be used to filter output results based upon matches to regular expressions (regex) by using the output list's column titles as keys.
Multiple key-value (i.e., column-title=regex) pairs can be provided on the same --where filter flag using commas.
Syntax: [--where key=regex[,...]]
See each command's section for contextual examples of the --where flag filter usage.
This command is used to aggregate and summarize software, hardware and data license information included in the SBOM. It also displays license usage policies for resources based upon concluded by SPDX license identifier, license family or logical license expressions as defined in he current policy file (i.e., license.json).
The license command supports the following subcommands:
- list - list or create a summarized report of licenses found in input SBOM.
- list with --summary flag - As full license information can be very large, a summary view is often most useful.
- policy - list user configured license policies by SPDX license ID, family name and other filters.
The list subcommand produces JSON output which contains an array of CycloneDX LicenseChoice data objects found in the BOM input file without component association. LicenseChoice data, in general, may provide license information using registered SPDX IDs, license expressions (of SPDX IDs) or license names (not necessarily registered by SPDX). License data may also include base64-encoded license or legal text that was used to determine a license's SPDX ID or name.

--wherefilter supports the keyspdx-idas an alias forid.
This command allows you to perform SQL-like queries into JSON format SBOMs. Currently, the command recognizes the --select and --from as well as the --where filter.
The --from clause value is applied to the JSON document object model and can return either a singleton JSON object or an array of JSON objects as a result. This is determined by the last property value's type as declared in the schema.
The --select clause is then applied to the --from result set to only return the specified properties (names and their values).
If the result set is an array, the array entries can be reduced by applying the --where filter to ony return those entries whose specified field names match the supplied regular expression (regex).
Note: All query command results are returned as valid JSON documents. This includes a null value for empty result sets.
The query command only supports JSON output.
json(default)
The query command does not support formatting of output results as JSON format is always returned.
This example effectively extracts the first-order package manifest from the SBOM.
In this example, only the --from clause is needed to select an object. The --select clause is omitted which is equivalent to using the "select all" wildcard character * which returns all fields and values from the component object.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from metadata.componentis equivalent to using the wildcard character (which may need to be enclosed in single or double quotes depending on your shell):
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --select '*' --from metadata.component --quiet{
"name": "Example Application v10.0.4",

"id": "Apache-2.0"

...In this example, the --from clause references the top-level metadata.supplier object.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from metadata.supplier --quiet{
"contact": [
{
"email": "[email protected]"
}
],
"name": "Example Co. Distribution Dept.",
"url": [
"https://example.com/software/"

}In this example, the --from clause references the singleton JSON object component found under the top-level metadata object. It then reduces the resultant JSON object to only return the name and value fields and their values as requested on the --select clause.
./sbom-utility query --select name,version --from metadata.component -i examples/cyclonedx/SBOM/juice-shop-11.1.2/bom.json --quiet{
"name": "juice-shop",
"version": "11.1.2"
}In this example, the --from filter will return the entire JSON components array.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from components --quiet[

]Note: The command for this example only used the --from flag and did not need to supply --select '*' as this us the default.
In this example, the --where filter will be applied to a set of properties results to only include entries that match the specified regex.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from metadata.properties --where name=urn:example.com:classification --quiet[
{
"name": "urn:example.com:classification",
"value": "This SBOM is Confidential Information. Do not distribute."
}
]additionally, you can apply a --select clause to simply obtain the matching entry's value:
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --select value --from metadata.properties --where name=urn:example.com:classification --quiet[
{
"value": "This SBOM is Confidential Information. Do not distribute."
}
]The resource command is geared toward inspecting various resources types and their information from SBOMs against future maturity models being developed as part of the OWASP Software Component Verification Standard (SCVS). In the SCVS model, a "resource" is the parent classification for software (components), services, Machine Learning (ML) models, data, hardware, tools and more.
Primarily, the command is used to generate lists of resources, by type, that are included in a CycloneDX SBOM by invoking resource list.
This command supports the --format flag with any of the following values:
txt(default),csv,md
Currently, all resource list command results are sorted by resource type then by resource name (required field).
./sbom-utility resource list -i test/cyclonedx/cdx-1-3-resource-list.json --quiettype name version bom-ref

These new schema entries will tell the schema loader where to find the JSON schema file locally, relative to the utility's executable.
For details see the "Adding SBOM formats, schema versions and variants" section.
If you wish to have the new schema embedded in the executable, simply add it to the project's resources subdirectory following the format and version-based directory structure.
This command is able to "trim" one or more JSON keys (fields) from specified JSON BOM documents effectively "pruning" the JSON document. This functionality helps consumers of large-sized BOMs that need to analyze specific types of data in large BOMs in reducing the BOM data to just what is needed for their use cases or needs.
This command is used to output, using the --output-file flag, a "trimmed" BOM in JSON format.
json(default)
Trim operates on a JSON BOM input file (see --input-file flag) and produces a trimmed JSON BOM output file using the following flags:
A comma-separated list of JSON map keys. Similar to the query command's --select flag syntax.
A comma-separated list of JSON document paths using the same syntax as the query command's --from flag.
The original BOM used for these examples can be found here:

}This command will parse standardized SBOMs and validate it against its declared format and version (e.g., SPDX 2.2, CycloneDX 1.4). Custom variants of standard JSON schemas can be used for validation by supplying the --variant name as a flag. Explicit JSON schemas can be specified using the --force flag.
Use the schema command to list supported schemas formats, versions and variants.
Customized JSON schemas can also be permanently configured as named schema "variants" within the utility's configuration file. See adding schemas.
The following flags can be used to improve performance when formatting error output results:
Use the --error-limit x (default: 10) flag to reduce the formatted error result output to the first x errors. By default, only the first 10 errors are output with an informational messaging indicating x/y errors were shown.
Use the --error-value=true|false (default: true) flag to reduce the formatted error result output by not showing the value field which shows detailed information about the failing data in the BOM.
Use the --colorize=true|false (default: false) flag to add/remove color formatting to error result txt formatted output. By default, txt formatted error output is colorized to help with human readability; for automated use, it can be turned off.

CVE-2020-25649 611 CVSSv31: 7.5 (high), CVSSv31: 8.2 (high), CVSSv31: 0 (none) NVD https://nvd.nist.gov/vuln/detail/CVE-2020-25649 2020-12-03 2023-02-02 2020-12-03 not_affected code_not_reachable com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. Affected versions of this package are vulnerable to XML External Entity (XXE) Injection. A flaw was found in FasterXML Jackson Databind, where it does not have entity expansion secured properly in the DOMDeserializer class. The highest threat from this vulnerability is data integrity.This experimental command will compare two similar BOMs and return the delta (or "diff") in JSON (diff-patch format) or text. This functionality is based upon code ancestral to that used to report file diffs between git commits.
- This command is undergoing analysis and tests which are exposing some underlying issues around "moved" objects in dependent diff-patch packages that may not be fixable and have no alternatives.
- Specifically, the means by which "moved" objects are assigned "similarity" scores appears flawed in the case of JSON.
- Additionally, some of the underlying code relies upon Go maps which do not preserve key ordering.
Use the --format flag on the to choose one of the supported output formats:
- txt (default), json
./sbom-utility diff -i test/diff/json-array-order-change-with-add-and-delete-base.json -r test/diff/json-array-order-change-with-add-and-delete-delta.json --quiet --format txt --colorize=true {

}This command will generate command-line completion scripts, for the this utility, customized for various supported shells.
The completion command can be invoked as follows:
./sbom_utility completion [shell]where valid values for shell are:
- bash
- fish
- powershell
- zsh
The utility supports the help command for the root command as well as any supported commands
For example, to list top-level (root command) help which lists the supported "Available Commands":
./sbom-utility helpA specific command-level help listing is also available. For example, you can access the help for the validate command:
./sbom-utility help validateThe utility itself is written in Go to advantage the language's built-in typing enforcement and memory safe features and its ability to be compiled for a wide range of target platforms and architectures.
The utility also is designed to produce output formats (e.g., JSON) and handle exit codes consistently to make it immediately useful standalone or as part of automated Continuous Integration (CI) tool chains for downstream use or inspection.
Further commands and reports are planned that prioritize use cases that enable greater insight and analysis of the legal, security and compliance data captured in the SBOM such as component provenance and signage (e.g., verifying resource identities by hashes or fingerprints).
In addition, inclusion of Continuous Integration and Delivery (CI/CD) or "build integrity" information around the BOM component is anticipated as part of the CycloneDX Formulation work which will require features for workflow insights.
The utility additionally prioritizes commands that help provide insight into contents of the BOM to search for and report on missing (i.e., completeness) or specific data requirements (e.g., organization or customer-specific requirements).
In general, the goal of these prioritized commands is to support data verification for many of the primary BOM use cases as identified by the CycloneDX community (see https://cyclonedx.org/use-cases/). Functional development has focused on those use cases that verify inventory (resource identity), legal compliance (e.g., license), and security analysis (e.g., vulnerability) which are foundational to any SBOM.
In the future, we envision support for additional kinds of BOMs (e.g., Hardware (HBOM), Machine Learning (MLBOM), etc.) with each again having different data requirements and levels of maturity which will increase the need for domain-specific validation. Specifically, this utility intends to support the work of the OWASP Software Component Verification Standard (SCVS) which is defining a BOM Maturity Model (BMM).

To build an executable of the utility compatible with your local computer's architecture use the build target in the project's Makefile:
cd sbom-utility/
make buildThe will produce a binary named sbom-utility with version set to latest in the project's release directory.
$ ls
-rwxr-xr-x 1 User1 staff 11501122 Jan 24 08:29 sbom-utility$ ./sbom-utility version
Welcome to the sbom-utility! Version `latest` (sbom-utility) (darwin/arm64)Note The binary created using make build will be for the local system's operating system and architecture (i.e., GOOS, GOARCH). This would effectively match what would be reported using the uname -s -m unix command when run on the same local system.
If you wish to build binaries for all supported combinations of GOOS and GOARCH values, use the release target (i.e., make release) which will produce named binaries of the form sbom-utility-${GOOS}-${GOARCH} under the release directory (e.g., sbom-utility-darwin-amd64).
Developers can run using the current source code in their local branch using go run main.go. For example:
go run main.go validate -i test/cyclonedx/cdx-1-4-mature-example-1.jsonThis project was developed using VSCode and can be seamlessly loaded as a project.
In order to see global variables while debugging a specific configuration, you can add the "showGlobalVariables": true to it within your launch.json config. file:
{
"showGlobalVariables": true,
"name": "Test name",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "main.go",
"args": ["validate", "-i", "test/cyclonedx/cdx-1-3-min-required.json","-t"]
},or add it globally to the settings.json file:
- Use
Command-Shift-Pto opensettings.json - Select "Preferences: Open Settings (JSON)"
- Add the following block at the top level:
"go.delveConfig": {
"showGlobalVariables": true
},Note: The showGlobalVariables setting was only recently disabled as the default in VSCode as a stop-gap measure due to performance (loading) problems under Windows.
The utility uses the config.json file (either the default, embedded version or the equivalent provided on the command line using --config-schema flag) to lookup supported formats and their associated versioned JSON schema files. To add another SBOM format simply add another entry to the format array in the root of the document:
{
"canonicalName": "SPDX",
"propertyKeyFormat": "SPDXID",
"propertyKeyVersion": "spdxVersion",
"propertyValueFormat": "SPDXRef-DOCUMENT",
"schemas": [
{
...
}
]
...
}The value for propertyKeyFormat should be the exact name of key field that would appear in the JSON SBOM itself which can be used to confirm it is indeed a format match. In addition, the corresponding value to match for that key should be declared in the propertyValueFormat value.
The fields canonicalName, propertyKeyFormat, propertyKeyVersion, and propertyValueFormat are required. The format object MUST have at least one valid schema object. The schema object appears as follows:
{
"version": "SPDX-2.2",
"file": "file://schema/spdx/2.2.1/spdx-schema.json",
"url": "https://raw.githubusercontent.com/spdx/spdx-spec/v2.2.1/schemas/spdx-schema.json",
"strict": false,
"latest": true,
"variant": ""
},- Add a copy of the JSON schema file locally in the project under the structure
resources/schema/<format>/<version>/<schema filename>.- Note If the schema exists under the
resourcesdirectory, it will automatically be embedded in in the executable binary when built usinggo buildwhich includes using the project'sMakefile.
- Note If the schema exists under the
- Assure only one
schemaobject entry for a given format and version has the valuelatestset totrue. This latest schema will be used when the SBOM being validated does not have a clear version declared or used with the--force latestflag. - If you have a customized or "variant" version of a schema (with the same format and version values) you wish to use for validation (e.g., a
corporateorstagingversion with added requirements or for testing an unreleased version), you can create an entry that has the sameversionas another entry, but also declare itsvariantname (non-empty value). This value can be supplied on the commend line with the--variant <variant name>flag to force the validator to use it instead of the default (empty variant value).
Contributions are welcome under the Apache 2.0 license.
The entirety of the code contains the tag "TODO" with comments of things that are features or improvements conceived while authoring the base functionality. Most of these do not have active issues opened form them.
Feel free to "grep" for the "TODO" tag, open an issue and/or submit a draft PR.
An ad-hoc list of featured "TODOs" geared at making the tool more accessible, extensible and useful especially around "core" commands such as validation.
- Merge command Support merge of two (both validated) SBOMs with de-duplication and configurable. Please note that some method of normalization prior to merge will be necessary.
- Remote Schema loading Support using SBOM schema files that are remotely hosted (network accessible) from known, trusted source locations (e.g., releases of SPDX, CycloneDX specification schemas). Note that the config file has an existing
urlfield per entry that can be used for this purpose. - --orderby Support ordering of query result sets by comparison of values from a specified field key.
- license.json Document license policy configuration JSON schema structure and how to add entries relative to a CycloneDX
LicenseChoiceobject for entries with SPDX IDs and those without. - license.json Add entries for all SPDX licenses listed in v3.21.
- See issue: CycloneDX#12
- Go libraries Replace
go-prettyjson,go-multimaplibraries with alternatives that produce maintained releases.

"version": "SPDX-2.3",
"variant": "",
"name": "SPDX v2.3",
"file": "schema/spdx/2.3/spdx-schema.json",

This value can be supplied on the commend line with the--variant <variant name>flag to force the validator to use it instead of the default (empty variant value).
The built-in go test command is used to execute all functional tests that appear in *._test.go files. By default, go test executes tests within the same directory where its respective *._test.go file is located and sets that as the working directory. For example, tests in the validate_test.go file are executed from the cmd subdirectory. This is a problem as the actual test SBOM JSON test files are located relative the project root, one level higher, and would not be found. In order to correct for that, the test working directory is automatically changed for all tests within the TestMain routine found in root_test.go.
The Makefile includes a test target for convenience which will use go test to run all tests found in all subdirectories:
make testThe test_cmd target will use run only the test found in the cmd package:
make test_cmdThe test_schema target will use run only the test found in the schema package:
make test_schemaExample: running all tests in the cmd package:
go test github.com/CycloneDX/sbom-utility/cmd -vExample: running all tests in the schema package:
go test github.com/CycloneDX/sbom-utility/schema -vRun in "quiet" mode to not see error test output:
go test github.com/CycloneDX/sbom-utility/cmd -v --quietrun an individual test within the cmd package:
go test github.com/CycloneDX/sbom-utility/cmd -v -run TestValidateCdx14MinRequiredBasicSimply append the flags --args --trace or --args --debug to your go test command to enable trace or debug output for your designated test(s):
go test github.com/CycloneDX/sbom-utility/cmd -v --args --traceSeveral tests will still output error and warning messages as designed. If these messages are distracting, you can turn them off using the --quiet flag.
go test github.com/CycloneDX/sbom-utility/cmd -v --args --quietNote: Always use the --args flag of go test as this will assure non-conflict with built-in flags.
