Uncaught Exception processing HTTP Headers in SurrealDB

High severity GitHub Reviewed Published Jan 17, 2024 in surrealdb/surrealdb

Package

cargo surrealdb (Rust)

Affected versions

< 1.1.0

Patched versions

1.1.0

Description

The ID, DB and NS headers accepted by the SurrealDB HTTP REST API would fail to parse when containing some special characters. This would cause a panic which would crash the SurrealDB server, leading to denial of service.

This issue only affects the SurrealDB binary; it does not affect the SurrealDB library.

Impact

An unauthenticated client may issue an HTTP request to the SurrealDB HTTP REST API containing one of the affected headers with values containing special characters in order to crash the SurrealDB server. This does not require the SurrealDB server to be running with any specific capabilities other than exposing the affected interface.

Patches

  • Version 1.1.0 and later are not affected by this issue.

Workarounds

Concerned users unable to update may want to limit untrusted access to the SurrealDB HTTP REST API unless such access is required by the application. To limit the impact of the denial of service, SurrealDB administrators may also want to ensure that the SurrealDB process is running so that it can be automatically re-started after a crash.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
