Loading vulnerability…
A command injection vulnerability exists in dev/less.php in Family Connections CMS (FCMS) versions 2.5.0 through 2.7.1. When the PHP configuration option register_globals is enabled, remote attackers can execute arbitrary commands on the server by supplying shell metacharacters in the argv[1] parameter, which is unsafely passed to a shell command.

This repository contains a single Metasploit module (modules/exploits/multi/http/familycms_less_exec.rb) that exploits a remote command execution vulnerability (CVE-2011-5130) in Family Connections CMS version 2.7.1 (and possibly other 2.5-2.7.1 versions). The vulnerability is present in the dev/less.php script due to insecure use of the system() function, and exploitation requires PHP's register_globals to be enabled. The module does not require authentication and allows the attacker to execute arbitrary system commands on the target server via a crafted GET request to the vulnerable endpoint. The exploit is fully weaponized within the Metasploit framework, supporting customizable command payloads. The main fingerprintable endpoints are the /fcms/ base path and the /dev/less.php script. The repository is structured as a single Ruby file following Metasploit conventions, with all exploit logic contained within the file.
