This repository contains a single Metasploit module (ultraminihttp_bof.rb) that exploits a stack-based buffer overflow vulnerability (CVE-2013-5019) in Ultra Mini HTTPD version 1.21 running on Windows systems. The exploit works by sending a specially crafted HTTP POST request with an excessively long resource name, causing a buffer overflow and allowing arbitrary code execution. The module includes logic to allocate executable memory, copy the payload, and execute it in a new thread to avoid process termination by the application's monitor thread. The exploit targets several Windows versions (2000, XP, Server 2003) and allows the attacker to run custom shellcode (such as a reverse shell) on the target. The only fingerprintable endpoint is the HTTP service exposed by the vulnerable Ultra Mini HTTPD instance. The code is written in Ruby and is designed to be used within the Metasploit framework.
