Loading vulnerability…
CVE-2017-6090 is an unrestricted file upload vulnerability in PhpCollab 2.5.1 and earlier. The flaw exists in clients/editclient.php, where remote authenticated users can upload files with executable extensions. These files are placed in the logos_clients/ directory and can be accessed directly, allowing attackers to execute arbitrary code on the server.

This repository contains a single Metasploit module (Ruby file) that exploits an unauthenticated file upload vulnerability in phpCollab version 2.5.1 (CVE-2017-6090). The exploit works by uploading a PHP payload to the server via a vulnerable endpoint and then triggering its execution, resulting in remote code execution as the web server user. The module is fully integrated with Metasploit, allowing the operator to select and deliver any compatible PHP payload (such as a reverse shell). The main endpoints targeted are the login page (for version checking), the file upload handler, and the location where the uploaded file is stored and executed. The exploit does not require authentication and is weaponized for operational use.
