Technical details
The vulnerability exists in IBM MQ's Managed File Transfer component due to improper input validation (CWE-20) of metadata used during script execution. An authenticated attacker with network access can craft malicious script metadata that bypasses validation controls, allowing arbitrary code execution on the MFT agent host. The attack requires authentication and higher complexity, but impacts multiple versions across LTS and CD release streams.
