Module Overview

Name: Canon Wireless Printer Denial Of Service
Module: auxiliary/dos/http/canon_wireless_printer
Source code: modules/auxiliary/dos/http/canon_wireless_printer.rb
Disclosure date: 2013-06-18
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: CVE-2013-4615

The HTTP management interface on several models of Canon Wireless printers allows for a Denial of Service (DoS) condition via a crafted HTTP request. Note: if this module is successful, the device can only be recovered with a physical power cycle.
