CVE-2009-4769 describes multiple format string vulnerabilities in the tolog function of httpdx versions 1.4 through 1.5. The vulnerability exists because user-supplied input is passed unsafely as a format string to logging functions. Specifically, remote attackers can exploit this by sending specially crafted GET requests to the HTTP server component, or authenticated users can exploit it via the PWD command to the FTP server component, both when logging is enabled. This allows attackers to control the format string, leading to arbitrary code execution.

This repository contains a single Metasploit module (Ruby file) that exploits a format string vulnerability (CVE-2009-4769) in the HTTPDX FTP server (versions 1.4 through 1.5) running on Windows XP SP3 English. The exploit targets the tolog() function, which is invoked when logging is enabled for the 'moderator' user. By sending a specially crafted FTP command containing format specifiers, the attacker can overwrite memory and execute arbitrary code. The module uses an egghunter to locate the payload in memory and supports automatic or manual target selection based on the FTP banner. The exploit requires valid FTP credentials (default: moderator/pass123) and targets TCP port 21. The payload is customizable via Metasploit and typically results in a remote shell or Meterpreter session. The code is operational and leverages Metasploit's framework for payload delivery and session handling.
This repository contains a single Metasploit module (modules/exploits/windows/http/httpdx_tolog_format.rb) that exploits a format string vulnerability (CVE-2009-4769) in the HTTPDX HTTP server (versions 1.4 through 1.5) running on Windows XP SP3 English. The exploit works by sending specially crafted HTTP requests containing format specifiers to the server, which, when logging is enabled (typically for the 'moderator' user via FTP), can corrupt memory and allow arbitrary code execution. The module uses an egghunter technique to locate and execute the payload in memory. The exploit supports automatic and manual targeting of specific HTTPDX versions, and the payload is customizable. The only fingerprintable endpoint is the HTTPDX HTTP server itself, which must be accessible to the attacker. The repository is a typical Metasploit exploit module, written in Ruby, and is operational in maturity, providing a working exploit with customizable payload delivery.
