Loading vulnerability…
A directory traversal vulnerability exists in the GfdFileUploadServerlet servlet in Lexmark MarkVision Enterprise prior to version 2.1. The vulnerability allows remote attackers to write to arbitrary files on the server by exploiting improper input validation in file upload functionality. The specific vectors are not detailed, but the flaw is due to insufficient sanitization of file paths provided by the attacker.

This repository contains a single Metasploit module targeting Lexmark MarkVision Enterprise (MVE) versions prior to 2.1, specifically version 2.0 on Windows. The exploit leverages a directory traversal vulnerability in the GfdFileUploadServlet, allowing unauthenticated attackers to upload arbitrary files (including JSP webshells) to the Tomcat web root. The module first uploads a JSP to leak the working directory, then uploads a second JSP containing the attacker's payload, and finally executes it via an HTTP GET request. The exploit is operational and provides remote code execution as the web server user. The main endpoints involved are the file upload servlet (/mve/upload/gfd) and the web root where the JSP is placed. The code is written in Ruby and is structured as a standard Metasploit exploit module, making use of Metasploit's payload system for customizable post-exploitation actions.
