Loading vulnerability…
CVE-2025-4190 affects the CSV Mass Importer WordPress plugin through version 1.2. The plugin does not properly validate uploaded files, which allows a high-privilege authenticated user, such as an administrator, to upload arbitrary files to the server. The issue is particularly relevant in environments where such uploads should be restricted, for example in WordPress multisite deployments where even admin-level users may not be intended to upload executable or otherwise unsafe files. The core weakness is insufficient validation of uploaded file type/content, resulting in an unrestricted file upload condition.

This repository contains a working exploit for CVE-2025-4190, targeting the WordPress CSV Mass Importer plugin (version 1.2 and below). The exploit is implemented in a single Python script (CVE-2025-4190.py), which automates the process of authenticating to a WordPress site as an admin, generating a ZIP archive containing a simple PHP web shell, and uploading it via the vulnerable plugin's import functionality. If successful, the shell is placed in a web-accessible directory, allowing the attacker to execute arbitrary system commands via HTTP requests. The script requires the target URL and valid admin credentials. The repository also includes a README.md with detailed usage instructions and a requirements.txt listing the 'requests' library as a dependency. The exploit is operational and provides a basic, hardcoded PHP shell payload. No detection or scanning functionality is present; the script is solely for exploitation.
This repository contains a Python exploit script (CVE-2025-4190.py) targeting the WordPress CSV Mass Importer plugin (versions <= 1.2), which is vulnerable to an Admin+ Arbitrary File Upload (CVE-2025-4190). The exploit requires valid WordPress admin credentials. It authenticates to the target WordPress site, generates a ZIP archive containing a simple PHP web shell, and uploads it via the plugin's import functionality. If successful, the shell is accessible at '/wp-content/uploads/cmi-data/nxploited.php', allowing the attacker to execute arbitrary system commands via the 'cmd' GET parameter. The repository includes a README with detailed usage instructions, a requirements.txt listing 'requests' as a dependency, and an MIT license. The exploit is operational and provides a working web shell for remote code execution on vulnerable targets.
