The File Manager Advanced Shortcode WordPress plugin (up to version 2.3.2) fails to properly enforce restrictions on file MIME types during uploads via its shortcode functionality. This allows attackers to upload files with disallowed MIME types, such as PHP scripts, even when the allowed MIME type list is configured to exclude them. In some configurations, this vulnerability can be exploited by unauthenticated users, leading to remote code execution (RCE) on the affected WordPress site.

This repository contains a single Metasploit module targeting an unauthenticated remote code execution (RCE) vulnerability (CVE-2023-2068) in the WordPress File Manager Advanced Shortcode plugin (version 2.3.2 and lower), which requires File Manager Advanced version 5.0.5 or lower. The exploit abuses insufficient MIME type checking in the plugin's shortcode upload functionality, allowing an attacker to upload a PHP webshell or other payloads. The module supports multiple payload types, including PHP Meterpreter, Unix/Linux/Windows command execution, and dropper payloads. The attack is performed over HTTP(S) and can be executed without authentication in the worst-case scenario. The module is fully weaponized, leveraging Metasploit's payload and stager infrastructure, and provides remote code execution with the privileges of the web server user. The main entry point is the Ruby file 'modules/exploits/multi/http/wp_plugin_fma_shortcode_unauth_rce.rb', which implements all exploit logic, including endpoint discovery, payload upload, and execution.
