Description

Control Web Panel (CWP) before webpanel_version 1.16 contains an OS command injection vulnerability in the protected_directory user panel module that allows attackers to execute arbitrary commands by submitting unescaped input through the file POST parameter in the acc=deletedp action. Attackers can exploit this flaw, which passes attacker-controlled input directly into a shell_exec call, to achieve code execution in the user panel context.
