CVE-2018-17553 is a vulnerability in Navigate CMS 2.8, specifically in the navigate_upload.php script. The vulnerability allows authenticated attackers to upload files of dangerous types without restriction, combined with directory traversal via the 'id' parameter. By sending a crafted POST request with engine=picnik and id=../../../navigate_info.php, an attacker can upload a malicious PHP file to an arbitrary location, leading to remote code execution.

This repository contains a single Metasploit module (modules/exploits/multi/http/navigate_cms_rce.rb) targeting Navigate CMS versions 2.8 and prior. The exploit leverages two vulnerabilities: an authentication bypass (CVE-2018-17552) via SQL injection in the login process, and a file upload vulnerability (CVE-2018-17553) in navigate_upload.php that allows path traversal. The module first bypasses authentication, then uploads a PHP payload to an arbitrary location (navigate_info.php), and finally triggers execution of the payload via a GET request. The exploit provides unauthenticated remote code execution on the target server. The code is written in Ruby and is designed to be used within the Metasploit framework. The main endpoints involved are /navigate/login.php, /navigate_upload.php, and /navigate_info.php. The module is operational and provides a customizable PHP payload for post-exploitation.
