Loading vulnerability…
A stack-based buffer overflow exists in Easy File Sharing (EFS) Web Server version 6.8. The vulnerability is triggered by sending a long string in the UserID parameter within a cookie to the vfolder.ghp endpoint, allowing remote attackers to overflow the stack buffer and potentially execute arbitrary code.

This repository contains a single Metasploit module (efs_fmws_userid_bof.rb) that exploits a stack buffer overflow vulnerability (CVE-2014-3791) in Easy File Management Web Server versions 4.0 and 5.3 on Windows. The exploit works by sending a specially crafted HTTP request to the server, targeting a specific resource (default: /vfolder.ghp) and overflowing the stack via the UserID cookie. The module includes logic to fingerprint the server version by requesting /whatsnew.txt and parsing the response. The payload is customizable and delivered as part of the overflow, allowing for remote code execution. The exploit is operational and leverages Metasploit's payload generation and delivery mechanisms. The only file in the repository is the exploit module itself, written in Ruby and structured according to Metasploit's conventions.
