Exploitation Summary

EIP tracks 4 public exploits for CVE-2009-10006. PoCs published by Metasploit, Jason Geffner, Jason Geffner, dookie, including Metasploit module exploits/windows/misc/ufo_ai.

AI-analyzed exploit summary This is a functional Metasploit module exploiting a buffer overflow in the IRC client component of UFO: Alien Invasion 2.2.1. It crafts a malicious IRC server response to trigger a stack-based overflow, leading to arbitrary code execution on Mac OS X 10.5.8 x86 systems.

Description

UFO: Alien Invasion versions up to and including 2.2.1 contain a buffer overflow vulnerability in its built-in IRC client component. When the client connects to an IRC server and receives a crafted numeric reply (specifically a 001 message), the application fails to properly validate the length of the response string. This results in a stack-based buffer overflow, which may corrupt control flow structures and allow arbitrary code execution. The vulnerability is triggered during automatic IRC connection handling and does not require user interaction beyond launching the game.
