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

An issue was discovered in EJBCA before 6.15.2.6 and 7.x before 7.3.1.2. In several sections of code, the verification of serialized objects sent between nodes (connected via the Peers protocol) allows insecure objects to be deserialized.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Ejbca Primekey * 6.15.2.6 (excluding)
Ejbca Primekey 7.0.0 (including) 7.3.1.2 (excluding)

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.
