CVE-2013-10051 is a remote code execution vulnerability affecting InstantCMS 1.6 and earlier. The flaw is in the search view handler, where user-controlled input from the look parameter is incorporated into an eval() call without proper sanitization. Because the application concatenates attacker-supplied data into a PHP expression and executes it, a remote attacker can trigger arbitrary PHP execution by sending a crafted HTTP GET request. The provided description further indicates the exploit uses a base64-encoded payload delivered in the Cmd header, which is then executed in the context of the vulnerable web application.

This repository contains a single Metasploit module (modules/exploits/unix/webapp/instantcms_exec.rb) that exploits a remote PHP code execution vulnerability in InstantCMS version 1.6 and prior (CVE-2013-10051). The exploit leverages a dangerous use of eval() in the target application, allowing an attacker to execute arbitrary PHP code by sending a specially crafted HTTP GET request. The payload is delivered via a base64-encoded string in the 'Cmd' HTTP header, which is then decoded and executed on the server. The module includes a check method to verify vulnerability by looking for 'Build Date' in the phpinfo() output. The only required configuration is the URI path to the InstantCMS instance, which defaults to '/'. The exploit is weaponized, as it is part of the Metasploit framework and supports customizable payloads. The main attack vector is network-based, targeting the web application over HTTP.
