EasyFTP Server list.html path Stack Buffer Overflow

Description

This module exploits a stack-based buffer overflow in EasyFTP Server 1.7.0.11 and earlier. EasyFTP fails to check input size when parsing the 'path' parameter supplied to an HTTP GET request, which leads to a stack based buffer overflow. EasyFTP allows anonymous access by default; valid credentials are typically unnecessary to exploit this vulnerability. After version 1.7.0.12, this package was renamed "UplusFtp". Due to limited space, as well as difficulties using an egghunter, the use of staged, ORD, and/or shell payloads is recommended.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
