Loading vulnerability…
A vulnerability in the HTTP service of Cisco IOS versions 11.1 through 12.1 allows remote attackers to cause a denial of service by sending a specially crafted HTTP request containing a '%%' string in the URL. The vulnerable function fails to properly handle this malformed input, leading to a crash or hang of the HTTP service.

This repository contains a single Metasploit auxiliary module targeting a Denial of Service (DoS) vulnerability in Cisco IOS HTTP servers (CVE-2000-0380). The exploit works by sending a specially crafted HTTP GET request for the path '/%%' to the target device's HTTP server (typically on TCP port 80). Vulnerable versions are Cisco IOS 11.1 through 12.1, with successful testing reported on a Cisco 1600 Router running IOS v11.2(18)P. The exploit causes the device to become unresponsive, requiring a reboot. The module is written in Ruby and follows the standard Metasploit module structure, with the main logic implemented in the 'run' method. No payload is delivered beyond the malformed HTTP request, and the attack vector is network-based, requiring access to the device's HTTP service.
