A critical vulnerability in SugarCRM versions prior to 12.0 (fixed in Hotfix 91155) allows unauthenticated attackers to inject arbitrary PHP code via the EmailTemplates feature due to missing input validation. The flaw is present in the default configuration and can be exploited remotely without authentication, granting attackers privileged access to the underlying system.

This repository contains a single Metasploit module (modules/exploits/multi/http/sugarcrm_webshell_cve_2023_22952.rb) that exploits CVE-2023-22952, an unauthenticated remote code execution vulnerability in SugarCRM versions prior to 11.0.5 and 12.0.2. The exploit works by uploading a malicious PNG file with embedded PHP code to the /cache/images/ directory via the /index.php?module=EmailTemplates&action=AttachFiles endpoint, leveraging a missing authentication check. Once uploaded, the attacker can access the webshell via HTTP and execute arbitrary commands, including reverse shells and command stagers. The module supports multiple payload types (PHP, Unix command, Linux dropper) and is fully integrated into the Metasploit framework, allowing for easy payload customization and automated cleanup. The exploit is weaponized, requiring no authentication and providing full remote code execution as the web server user.
