Technical details
The /newpass/ API endpoint in CWP's loopback interface fails to sanitize the POST 'user' parameter before passing it to a shell command executed with root privileges. An attacker can inject arbitrary OS commands via shell metacharacters in the user parameter to achieve unauthenticated remote code execution as root. The vulnerability affects CWP before version 1.16 and has been patched.
