Loading vulnerability…
A directory traversal vulnerability exists in the MPAUploader.Uploader.1.UploadFiles method of HP Managed Printing Administration prior to version 2.6.4. Remote attackers can exploit this flaw by submitting crafted form data, allowing them to create arbitrary files on the server outside the intended upload directory.

This repository contains a single Metasploit module (hp_mpa_job_acct.rb) that exploits an arbitrary file upload vulnerability (CVE-2011-4166) in HP Managed Printing Administration 2.6.3 and prior on Windows systems. The exploit abuses the UploadFiles() function in the MPAUploader.Uploader.1 ActiveX control, allowing attackers to upload a malicious ASP file containing a base64-encoded EXE payload to a writable, web-accessible directory. The module attempts to upload the payload to several default directories under /hpmpa/userfiles/, but can be configured to use a custom path via the WRITEWEBFOLDER option. Once uploaded, the module triggers execution of the payload by sending an HTTP request to the uploaded ASP file, resulting in remote code execution with the privileges of the web server. The module is operational and allows for arbitrary payloads to be delivered and executed on the target. The code is written in Ruby and is structured as a standard Metasploit exploit module, leveraging the Metasploit framework's HTTP client and EXE generation capabilities.
