IBM QRadar SIEM 7.3 and 7.4 could allow a remote attacker to execute arbitrary commands on the system, caused by insecure deserialization of user-supplied content by the Java deserialization function. By sending a malicious serialized Java object, an attacker could exploit this vulnerability to execute arbitrary commands on the system. IBM X-Force ID: 176140.

Weakness

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

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.
