IBM QRadar 7.3.0 to 7.3.3 Patch 2 could allow an authenticated user to send a specially crafted command which would be executed as a lower privileged user. IBM X-ForceID: 175897.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Qradar_security_information_and_event_manager Ibm 7.3.0 (including) 7.3.3 (excluding)
Qradar_security_information_and_event_manager Ibm 7.3.3 (including) 7.3.3 (including)
Qradar_security_information_and_event_manager Ibm 7.3.3-p1 (including) 7.3.3-p1 (including)
Qradar_security_information_and_event_manager Ibm 7.3.3-p2 (including) 7.3.3-p2 (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.
