Control Web Panel Missing Authentication Remote Code Execution Vulnerability

Control Web Panel Missing Authentication Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Control Web Panel. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of authentication within the web interface. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of a valid CWP user. Was ZDI-CAN-20582.
