CVE-2020-5849 is an authentication bypass vulnerability affecting Unraid 6.8.0. According to the provided content, an unauthenticated attacker can gain access to the administrative interface by prepending a whitelisted image path to otherwise protected page URIs. This indicates improper enforcement of authentication on requests that are interpreted as matching an allowed resource path, enabling access control checks to be bypassed for admin pages.

This repository contains a single Metasploit module (modules/exploits/linux/http/unraid_auth_bypass_exec.rb) targeting Unraid version 6.8.0. The exploit leverages two vulnerabilities (CVE-2020-5847 and CVE-2020-5849): an authentication bypass and an insecure use of PHP's extract() function, allowing unauthenticated remote code execution as root. The module is written in Ruby and uses Metasploit's HttpClient and PhpEXE mixins. The exploit works by sending a specially crafted GET request to the '/webGui/images/green-on.png/' endpoint, injecting a base64-encoded PHP payload via GET parameters. If successful, the payload is executed on the target system. The module includes a check method to verify if the target is running the vulnerable version. The only file in the repository is the exploit module itself, and it is fully operational within the Metasploit framework.
