Loading vulnerability…
A buffer overflow vulnerability exists in the streaming media component for logging multicast requests (nsiislog.dll) in Microsoft Windows Media Services as installed in IIS 5.0. The flaw is triggered by sending a large POST request to nsiislog.dll, which does not properly validate input size, leading to a stack-based buffer overflow and potential execution of arbitrary code.

This repository contains a single Metasploit module (ms03_022_nsiislog_post.rb) that exploits a buffer overflow vulnerability in the nsiislog.dll ISAPI filter, which is part of Windows Media Services on Microsoft IIS servers. The exploit targets systems vulnerable to CVE-2003-0349 (MS03-022), including specific versions of Windows 2000 and Windows XP. The module sends a specially crafted HTTP POST request to the vulnerable DLL (default path: /scripts/nsiislog.dll), overflowing a buffer and overwriting the SEH handler to execute arbitrary code. The payload is customizable via Metasploit and typically results in a reverse shell or Meterpreter session. The module includes brute force targeting for different versions and offsets. The only fingerprintable endpoint is the URL path to the vulnerable DLL. The code is mature, weaponized, and ready for operational use within the Metasploit framework.
