A vulnerability in Microsoft Windows NAT Helper Components (ipnathlp.dll) on Windows XP SP2, when Internet Connection Sharing is enabled, allows remote attackers to cause a denial of service by sending a malformed DNS query. The vulnerability is due to a null pointer dereference in the handling of DNS queries, resulting in a crash of the svchost.exe process.

This repository contains a single Metasploit auxiliary module targeting a denial of service (DoS) vulnerability in the Internet Connection Sharing (ICS) service on Microsoft Windows XP (CVE-2006-5614). The exploit is implemented in Ruby and leverages the Metasploit framework's auxiliary and UDP modules. The main exploit logic is in the 'run' method, which constructs and sends a specially crafted UDP packet to port 53 of the target system. Successful exploitation results in the crash of the NAT Helper service, causing a denial of service and disrupting network connectivity. The module is operational and does not provide a shell or further access, focusing solely on service disruption. The only fingerprintable endpoint is UDP port 53 on the target system.
