Loading vulnerability…
A format string vulnerability exists in SHOUTcast 1.9.4, where remote attackers can supply format string specifiers in a content URL, specifically in the filename portion of a .mp3 file. This flaw allows attackers to manipulate the format string processing, potentially leading to application crashes or arbitrary code execution.

This repository contains a single Metasploit module (modules/exploits/windows/http/shoutcast_format.rb) that exploits a format string vulnerability (CVE-2004-1373) in Nullsoft SHOUTcast DNAS/win32 version 1.9.4 and earlier. The exploit targets the SHOUTcast server running on Windows platforms (NT, 2000, XP, 2003) and is triggered by sending a specially crafted HTTP request to the server (default port 8000). The request includes format string specifiers in the file path, allowing the attacker to execute arbitrary code. The module supports customizable payloads (up to 250 bytes, with specific bad characters avoided) and provides remote code execution on the target. The code includes a version check to identify vulnerable SHOUTcast instances. The main attack vector is network-based, leveraging HTTP requests to the SHOUTcast service. No hardcoded IPs or domains are present; the exploit is generic and targets any accessible vulnerable SHOUTcast server.
