Loading vulnerability…
OpenX adserver 2.8.1 and earlier contain an unrestricted file upload vulnerability in banner-edit.php. Authenticated users with banner or file upload permissions can upload files with executable extensions. These files are placed in an images directory and can be accessed directly, allowing attackers to execute arbitrary code on the server.

This repository contains a single Metasploit module (openx_banner_edit.rb) that exploits a file upload vulnerability in OpenX advertising software versions prior to 2.8.2 (CVE-2009-4098). The exploit targets authenticated users, allowing them to upload a PHP file disguised as a valid image (GIF, PNG, or JPEG) via the banner management interface. The module handles authentication, campaign and advertiser selection, banner upload, and execution of the payload. The payload is arbitrary PHP code, enabling remote code execution on the target server. The module interacts with several HTTP endpoints within the OpenX admin interface, including paths for login, banner upload, and management. The code is written in Ruby and is designed to be used within the Metasploit framework. The exploit is operational, requiring valid credentials and a vulnerable OpenX installation, and provides the attacker with remote code execution capabilities.
