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

A PHP object injection bug in profile.php in qcubed (all versions including 3.1.1) unserializes the untrusted data of the POST-variable strProfileData and allows an unauthenticated attacker to execute code via a crafted POST request.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Qcubed Qcubed * 3.1.1 (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.
