Loading vulnerability…
A buffer overflow vulnerability exists in the mDNSResponder component of Apple Mac OS X versions 10.4 through 10.4.9. The flaw is triggered when the service processes a specially crafted UPnP Internet Gateway Device (IGD) packet, leading to a buffer overflow condition. This can result in the termination of the mDNSResponder process or potentially allow remote code execution.

This repository contains a single Metasploit module: 'Mac OS X mDNSResponder UPnP Location Overflow'. The exploit targets a buffer overflow vulnerability (CVE-2007-2386) in the mDNSResponder service on Mac OS X 10.4.0 through 10.4.9 (unpatched). The module is written in Ruby and leverages the Metasploit framework's UDP and payload handling capabilities. The exploit works by sending specially crafted UPnP discovery replies to the target's mDNSResponder service over UDP (primarily port 1900 and high ports in the 49152-65535 range). The malicious response includes a long 'Location' header that overflows a buffer, allowing arbitrary code execution. The module supports both x86 and PPC architectures and allows the attacker to deliver a custom payload (such as a shell) to the vulnerable system. The code includes logic to scan for the correct UPnP port and to maintain a TCP connection as required for reliable exploitation. No hardcoded IPs or domains are present; the attacker configures the relevant network parameters. The repository is operational and provides a working exploit for the specified vulnerability.
