Technical details
The vulnerability is an OS command injection (CWE-78) in the protected_directory user panel module where the acc=deletedp action passes unescaped user input from the file POST parameter directly to shell_exec without sanitization. This allows authenticated or unauthenticated network attackers to inject shell metacharacters and execute arbitrary commands with the privileges of the web panel process. A fix is available in version 1.16 and later.
