CWEhttps://cwe.mitre.org/data/definitions/502.html

Serialization of sensitive data in GitLab EE affecting all versions from 14.9 prior to 15.2.5, 15.3 prior to 15.3.4, and 15.4 prior to 15.4.1 can leak sensitive information via cache

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Gitlab Gitlab 14.9 (including) 15.2.5 (excluding)
Gitlab Gitlab 15.3 (including) 15.3.4 (excluding)
Gitlab Gitlab 15.4 (including) 15.4.1 (excluding)
Gitlab Ubuntu esm-apps/xenial *
Gitlab Ubuntu trusty *
Gitlab Ubuntu xenial *

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
