Loading vulnerability…
Gibbon through version 26.0.00 is vulnerable to a PHP deserialization attack. An authenticated remote user can exploit the 'columnOrder' parameter in a POST request to the 'modules/System Admin/import_run.php' endpoint (with type=externalAssessment and step=4) to inject malicious serialized PHP objects, leading to arbitrary code execution or other attacks depending on the application's object handling.

This repository contains a Metasploit module that exploits CVE-2024-24725, a remote code execution vulnerability in the Gibbon online school platform (version 26.0.00 and lower). The exploit targets an authenticated PHP deserialization flaw in the '/modules/System Admin/import_run.php&type=externalAssessment&step=4' endpoint. The module requires valid credentials and leverages Metasploit's payload system to deliver a variety of payloads, including PHP Meterpreter, command execution for Unix/Linux/Windows, and staged droppers. The exploit is highly weaponized, supporting multiple platforms and payload types, and is designed for reliable, repeatable exploitation. The repository consists of a single Ruby file structured as a standard Metasploit exploit module, with all logic encapsulated within the class. The main attack vector is network-based, requiring HTTP(S) access to the vulnerable endpoint. The module also includes checks to verify the target's version and platform before exploitation.
