AI-suggested
Since the vulnerability requires network access to TCP port 16017, restricting or monitoring access to this port may reduce exposure. Users should consult IBM's official advisories for updates and apply any forthcoming patches promptly. Until a fix is available, minimizing network exposure of the CAS listener port is recommended.
Description
IBM Guardium Data Protection version 12.2 contains a critical vulnerability involving improper control of code generation (CWE-94) in the Change Audit System (CAS) listener. This flaw allows unauthenticated network attackers who can access TCP port 16017 to submit crafted serialized messages that may lead to unintended code execution on the Guardium appliance. The vulnerability has a high CVSS score of 9.8, indicating severe impact on confidentiality, integrity, and availability.
