Loading vulnerability…
Buffer overflow in the Private Communications Transport (PCT) protocol implementation in the Microsoft SSL library (PCT 1.0 handshake processing). A remote attacker can trigger the overflow by sending crafted PCT 1.0 handshake packets to a service/application using the affected Microsoft SSL library, resulting in arbitrary code execution.

This repository contains a single Metasploit module (ms04_011_pct.rb) that exploits a buffer overflow vulnerability in the Microsoft Windows SSL PCT protocol stack (CVE-2003-0719, MS04-011). The exploit targets Windows 2000 (SP0-SP4) and Windows XP (SP0, SP1) systems running SSL-enabled services, such as SMTP with STARTTLS or raw SSL services. The module connects to the specified TCP port, optionally negotiates SMTP STARTTLS, and sends a specially crafted buffer to trigger the overflow and execute arbitrary code (payload) on the target. The payload is provided by the Metasploit framework and can be customized by the user. The exploit requires the attacker to select the correct target version for reliable exploitation. The code is written in Ruby and is structured as a standard Metasploit exploit module, making use of the framework's payload and handler systems.
