Authenticated Arbitrary File Upload RCE in PHP Volunteer Management System v1.0.2

IdentifiersCVE-2012-10056CWE-434· Unrestricted Upload of File with…

CVE-2012-10056 affects PHP Volunteer Management System v1.0.2. The application’s document upload functionality allows authenticated users to upload files into the mods/documents/uploads/ directory without effective validation or restriction of file type or extension. Because the upload location is publicly reachable and does not prevent execution of uploaded server-side scripts, an attacker can upload a malicious PHP payload, such as a web shell, and then invoke it directly over HTTP with a GET request. The provided context also states that the application ships with default credentials, which materially lowers the barrier to exploitation by making authenticated access trivial in default deployments.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in remote code execution in the context of the web server process. An attacker can deploy and execute a PHP web shell, enabling arbitrary command execution, persistent backdoor access, manipulation or theft of application data, use of the compromised host as a pivot point, and broader compromise of the underlying server depending on the privileges of the web service account and local environment.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, disable the document upload feature or restrict it to trusted administrators only. Enforce strong unique credentials and eliminate default accounts. Apply web server controls to deny execution of PHP and other server-side scripts in mods/documents/uploads/. Restrict direct web access to uploaded content where possible, monitor the upload directory for unexpected executable content, and inspect logs for suspicious authentication and follow-on GET requests to uploaded files.

Remediation

Patch, then assume compromise.

Upgrade to a fixed version if one is available from the vendor. Implement strict server-side allowlisting for uploaded file types and reject executable/script extensions such as .php, .phtml, and similar interpreter-handled formats. Store uploaded files outside the web root or in a location that cannot be requested directly via HTTP. Configure the web server to disable script execution in upload directories. Remove or change all default credentials during deployment and review for any unauthorized uploaded files, especially PHP shells, in mods/documents/uploads/.

php_volunteer_upload_exec.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module (modules/exploits/multi/http/php_volunteer_upload_exec.rb) targeting PHP Volunteer Management System v1.0.2 and prior. The exploit leverages an arbitrary file upload vulnerability, allowing an authenticated attacker (using default credentials) to upload a malicious PHP file to a web-accessible directory. The module automates the process: it logs in, uploads a PHP payload, locates the uploaded file (which may be renamed), and then triggers its execution via an HTTP GET request. The payload is customizable and typically provides remote code execution (e.g., a reverse shell or Meterpreter session). The exploit is weaponized, as it is part of the Metasploit framework and supports flexible payloads. The main endpoints involved are the login page, the file upload handler, and the uploads directory where the payload is executed. The repository is structured as a single Ruby file implementing the exploit logic for Metasploit.
