This repository contains a single Metasploit auxiliary scanner module targeting path traversal vulnerabilities in LimeSurvey (CVE-2020-11455 and CVE-2019-9960). The module allows an authenticated attacker to download arbitrary files from the server by exploiting vulnerable endpoints in LimeSurvey's file management and export functionality. The exploit works by sending crafted HTTP GET requests with path traversal sequences to specific endpoints, retrieving files such as /etc/passwd. The module supports multiple LimeSurvey versions and automatically determines the appropriate exploit method based on the detected version. The code is written in Ruby and is structured as a typical Metasploit module, requiring valid LimeSurvey credentials to authenticate before exploitation. The main file is 'modules/auxiliary/scanner/http/limesurvey_zip_traversals.rb', and the attack vector is network-based, targeting HTTP endpoints exposed by the LimeSurvey application.
