Description
OTRS Community Edition contains an authenticated OS command injection vulnerability in the PGP encryption module that allows administrators to execute arbitrary operating-system commands by supplying crafted values for the PGP binary path and command options. Administrator-supplied configuration values are concatenated without sanitization into a shell command, enabling arbitrary command execution as the web server process user during normal ticket operations after the malicious configuration is deployed.
