Module Overview

Name: IBM Lotus Sametime WebPlayer DoS
Module: auxiliary/dos/misc/ibm_sametime_webplayer_dos
Source code: modules/auxiliary/dos/misc/ibm_sametime_webplayer_dos.rb
Disclosure date: 2013-11-07
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 5060
List of CVEs: CVE-2013-3986

This module exploits a known flaw in the IBM Lotus Sametime WebPlayer version 8.5.2.1392 (and prior) to cause a denial of service condition against specific users. For this module to function the target user must be actively logged into the IBM Lotus Sametime server and have the Sametime Audio Visual browser plug-in (WebPlayer) loaded as a browser extension. The user should have the WebPlayer plug-in active (i.e. be in a Sametime Audio/Video meeting for this DoS to work correctly.
