Apollo has potential access control security issue in eureka

High severity GitHub Reviewed Published Feb 18, 2023 in apolloconfig/apollo • Updated Feb 22, 2023

Package

maven com.ctrip.framework.apollo:apollo (Maven)

Affected versions

< 2.1.0

Patched versions

2.1.0

Description

Impact

If users expose the apollo-configservice to the internet (which is not recommended), there are potential security issues since there is no authentication feature enabled for the built-in eureka service. Malicious hackers may access eureka directly to mock apollo-configservice and apollo-adminservice .

Patches

Login authentication for eureka was added in apolloconfig/apollo#4663 and was released in v2.1.0.

Workarounds

To fix the potential issue without upgrading, simply follow the advice that does not expose apollo-configservice to the internet.

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.
