qdPM through 9.1 allows PHP Object Injection via timeReportActions::executeExport in core/apps/qdPM/modules/timeReport/actions/actions.class.php because unserialize is used.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Qdpm Qdpm * 9.1 (including)

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.
