Buffer Overflow in Microsoft PPTP Service (Windows XP/2000)

IdentifiersCVE-2002-1214CWE-120

A buffer overflow vulnerability exists in the Microsoft PPTP Service on Windows XP and Windows 2000. The flaw is triggered by processing a specially crafted PPTP packet containing malformed control data, which can cause the service to hang and may allow remote attackers to execute arbitrary code.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in a denial of service (service hang) or potentially allow remote code execution with the privileges of the PPTP service, leading to full system compromise.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to the PPTP service to trusted networks only, and use network-level controls such as firewalls to block untrusted traffic to the PPTP port (TCP 1723).

Remediation

Patch, then assume compromise.

Apply the security patch provided by Microsoft for this vulnerability. Ensure all affected systems are updated to the latest service packs and security updates.

ms02_063_pptp_dos.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit auxiliary module (modules/auxiliary/dos/pptp/ms02_063_pptp_dos.rb) that exploits a denial of service vulnerability (CVE-2002-1214, MS02-063) in Microsoft Windows 2000 (SP0-SP3) and Windows XP (SP0-SP1) systems running PPTP RAS servers. The exploit works by sending a specially crafted PPTP control packet with an excessively long Vendor field to TCP port 1723 (the default PPTP port) on the target. This causes a kernel memory overwrite, resulting in a system crash (BSOD). The module does not attempt code execution and is strictly a denial of service (DoS) exploit. The code is written in Ruby and is designed to be run within the Metasploit Framework. No hardcoded IP addresses or domain names are present; the only fingerprintable endpoint is the TCP port 1723, which is standard for PPTP services.
