Summary

OTRS Community Edition has an authenticated OS command injection vulnerability in the PGP encryption module that allows administrators to execute arbitrary commands by supplying crafted values for the PGP binary path and command options. The values are concatenated without sanitization into a shell command, enabling command execution as the web server user.

Risk Assessment

An administrator (or someone with admin privileges) can execute arbitrary commands on the server, potentially leading to full system compromise, data theft, or further attacks.

Recommendation

Upgrade OTRS Community Edition to a patched version and restrict trust in administrators and validate configuration inputs.
