Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.08%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A command injection (missing input validation, escaping) in the monitoring or memory status web interface in AudioCodes 405HD (firmware 2.2.12) VoIP phone allows an authenticated remote attacker in the same network as the device to trigger OS commands (like starting telnetd or opening a reverse shell) via a POST request to the web server. In combination with another attack (unauthenticated password change), the attacker can circumvent the authentication requirement.
