CVE-2002-0649 is a remotely exploitable buffer overflow in the SQL Server Resolution Service / SQL Server Resolution Service (SSRS) component of Microsoft SQL Server 2000 and Microsoft Desktop Engine 2000 (MSDE). The vulnerable service listens on UDP port 1434 and improperly handles crafted packets. Reported attack vectors include a packet containing a 0x04 byte that causes the SQL Monitor thread to generate an overly long registry key name, and a packet containing a 0x08 byte followed by a long string that triggers heap corruption. Successful exploitation can cause denial of service or arbitrary code execution in the context of the SQL Server service account. This is the vulnerability later mass-exploited by the SQL Slammer/Sapphire worm.

This repository contains a single Metasploit module (ms02_039_slammer.rb) that exploits a buffer overflow vulnerability in the Microsoft SQL Server 2000 and MSDE (pre-SP3) resolution service (CVE-2002-0649). The exploit works by sending a specially crafted UDP packet to port 1434, triggering a stack-based buffer overflow and allowing arbitrary code execution with the privileges of the SQL Server service. The module is written in Ruby and leverages the Metasploit framework's payload system, allowing the attacker to inject custom shellcode. The exploit is operational and requires the target to be running a vulnerable version of SQL Server or MSDE with the resolution service exposed. The only fingerprintable endpoint is UDP port 1434, which is the standard port for the SQL Server resolution service.
