CVE-2011-10029 is a format string vulnerability in Solar FTP Server. The server does not properly handle format strings supplied to the FTP USER command. An attacker can send a specially crafted username containing format specifiers, which is then processed unsafely and triggers a read access violation in the __output_1() function of sfsservice.exe. Based on the provided information, successful exploitation causes the service to crash, resulting in a denial of service condition.

This repository contains a single Metasploit auxiliary module targeting a denial of service vulnerability in Solar FTP Server (versions 2.1.1 and earlier) on Windows. The exploit works by connecting to the target's FTP service (TCP port 21) and sending a specially crafted USER command containing a format string. This triggers a READ violation in the 'sfsservice.exe' process, causing the server to crash. The module is written in Ruby and follows the standard Metasploit structure, with the main logic implemented in the 'run' method. No payload is delivered beyond the malformed USER command, and the exploit is designed solely to demonstrate the vulnerability (POC). The only endpoints referenced are the FTP service port and the vulnerable executable. The module references CVE-2011-10029 and is not a detection script or fake exploit.
