Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary commands with root privileges and disclose sensitive files.
The vulnerability exists due to OS command injection in Roxy-WI's unprotected Flask-APScheduler API when processing attacker-controlled job functions and arguments after authentication bypass using ?api=1. A remote attacker can submit func=os:system to /scheduler/jobs?api=1, trigger /scheduler/jobs/<id>/run?api=1, and redirect command output into app/static/ for retrieval through /static/<file>?api=1 to compromise the server and read /etc/shadow.
