A directory traversal vulnerability exists in the TFTP Server 1.0.0.24 component of Ipswitch WhatsUp Gold. The vulnerability is due to insufficient sanitization of the Filename field in RRQ (Read Request) operations, allowing remote attackers to include '..' sequences and access arbitrary files on the server's filesystem.

This repository contains a single Metasploit auxiliary scanner module targeting a directory traversal vulnerability (CVE-2011-4722) in the TFTP service of IpSwitch WhatsUp Gold. The module exploits the vulnerability by sending a specially crafted TFTP read request with a filename containing directory traversal sequences (e.g., ../../../../windows/win.ini), allowing the attacker to retrieve arbitrary files from the target system. The exploit operates over UDP port 69 (TFTP) and is designed to work against default configurations where write requests are forbidden but read requests are allowed. The module can save the retrieved file to disk for further analysis. The code is written in Ruby and follows the standard Metasploit module structure, with options to specify the target file and whether to save the output. No remote code execution is possible with this exploit; its impact is limited to unauthorized file disclosure.
