No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

ICEcoder 8.1 contains an unauthenticated remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary OS commands by chaining an authentication bypass, CSRF validation bypass, and unsanitized command execution. Attackers can send a single HTTP POST request to the terminal endpoint with a password parameter to bypass authentication, a non-empty csrf parameter to skip CSRF validation, and an arbitrary command string passed directly to proc_open() to achieve remote code execution as the web-server user.
