CVE-2021-32682 encompasses multiple critical vulnerabilities in elFinder 2.1.58, a widely used web file manager. The vulnerabilities include arbitrary file deletion, arbitrary file moving, PHP file upload, argument injection, and a race condition, all of which can be exploited without authentication in the default configuration. The root cause is improper handling of user-controlled paths and insufficient validation in file system operations, affecting even the minimal connector. Attackers can chain these issues to bypass security controls and achieve arbitrary code execution on the server.

This repository contains a single Metasploit module targeting a command injection vulnerability (CVE-2021-32682) in elFinder versions below 2.1.59. The exploit abuses the archive creation functionality by injecting malicious arguments into the 'name' parameter, which is insufficiently sanitized before being passed to the system's 'zip' utility. The module is written in Ruby and leverages Metasploit's HttpClient, FileDropper, and CmdStager mixins to automate exploitation. It first uploads a text file, then creates a malicious archive to trigger command execution, ultimately delivering a payload such as a reverse shell. The module checks for the presence and version of elFinder by probing specific HTTP endpoints, and cleans up artifacts after exploitation. The only file present is the Metasploit exploit module itself, and it is fully operational, providing remote code execution as the www-data user on vulnerable systems.
