Technical details

An OS command injection vulnerability in IBM API Connect 10.0.8.0–10.0.8.12 and 12.1.0.0–12.1.1.2 allows authenticated attackers to execute arbitrary commands. User-supplied input is not properly neutralized before being passed to the operating system, enabling command execution on the host. The attack requires prior authentication but can lead to full system compromise.

Affected products
