Loading vulnerability…
The Modern Events Calendar Lite WordPress plugin, in versions prior to 5.16.5, contains an arbitrary file upload vulnerability. The plugin fails to properly validate the type of files being imported, allowing an attacker with administrator privileges to upload arbitrary PHP files by specifying the 'text/csv' content-type in the request. This bypasses the intended file type restrictions.

This repository contains a single Metasploit module targeting an authenticated remote code execution vulnerability (CVE-2021-24145) in the Wordpress plugin Modern Events Calendar (versions < 5.16.5). The exploit requires valid Wordpress admin credentials and abuses an arbitrary file upload flaw, allowing an attacker to upload a PHP payload by disguising it as a CSV file. The payload is then executed by accessing it via the /wp-content/uploads/ directory. The module is fully weaponized, leveraging Metasploit's payload and session management, and provides remote code execution as the web server user. The code is written in Ruby and follows standard Metasploit module structure, with clear separation of check and exploit routines. The main network endpoints involved are the Wordpress admin upload handler and the uploads directory for payload execution.
This repository provides a working exploit for CVE-2021-24145, a vulnerability in the Modern Events Calendar Lite WordPress plugin (versions before 5.16.5) that allows authenticated administrators to upload arbitrary files, including PHP web shells, by abusing the plugin's import functionality. The main exploit script is 'poc.py', a Python script that automates the attack: it authenticates to the WordPress admin panel using provided credentials, then uploads a PHP web shell (based on p0wny shell) to the server via a crafted multipart/form-data request with a 'text/csv' content-type. Upon success, the shell is accessible at '/wp-content/uploads/shell.php' on the target server, granting remote code execution. The repository also includes a Docker Compose setup for local testing, with a preconfigured WordPress and MySQL environment, and an .htaccess file to increase upload limits. The exploit is operational, requiring valid admin credentials, and is not a detection script. The main attack vector is web-based, targeting the vulnerable plugin's import endpoint.
