In Katello 1.5.0-14 and earlier, and Red Hat Satellite, the users controller fails to enforce authorization checks for the update_roles action. This allows a remote authenticated user to escalate privileges by modifying their own or another user's account to have administrator rights, bypassing intended access controls.

This repository contains a single Metasploit auxiliary module targeting a privilege escalation vulnerability (CVE-2013-2143) in Katello and Red Hat Satellite (Katello 1.5.0-14 and earlier). The exploit abuses a missing authorization check in the 'update_roles' action of the 'users' controller, allowing an authenticated user to escalate their privileges to administrator. The module performs the following steps: authenticates to the application, retrieves a valid session and CSRF token, identifies the user ID, and sends a crafted HTTP PUT request to the /users/<user_id>/update_roles endpoint to assign the admin role. The code is written in Ruby and leverages the Metasploit framework's HTTP client utilities. The only file present is the exploit module itself, and it is operational, requiring valid credentials to execute successfully. The main endpoints involved are /user_session/new (login), /dashboard (token/user id retrieval), and /users/<user_id>/update_roles (privilege escalation).
