Module Overview

Name: MS02-063 PPTP Malformed Control Data Kernel Denial of Service
Module: auxiliary/dos/pptp/ms02_063_pptp_dos
Source code: modules/auxiliary/dos/pptp/ms02_063_pptp_dos.rb
Disclosure date: 2002-09-26
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 1723
List of CVEs: CVE-2002-1214

This module exploits a kernel based overflow when sending abnormal PPTP Control Data packets to Microsoft Windows 2000 SP0-3 and XP SP0-1 based PPTP RAS servers (Remote Access Services). Kernel memory is overwritten resulting in a BSOD. Code execution may be possible however this module is only a DoS.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
