Loading vulnerability…
CVE-2023-30943 is a vulnerability in Moodle where the application allows a user to control the path of the folder to create in TinyMCE loaders. This enables a remote attacker to send a specially crafted HTTP request to create arbitrary folders on the system, potentially outside the intended directory structure.

This repository contains a single Python exploit script (CVE-2023-30943.py) and a README.md with a disclaimer. The exploit targets Moodle installations vulnerable to CVE-2023-30943. The script demonstrates three main attack vectors: (1) Unauthenticated arbitrary folder creation in the Moodle web root, which can be leveraged for stored XSS by crafting malicious file paths; (2) Construction of a malicious OAuth2 confirmation URL that can be used in a self-XSS attack to take over accounts; (3) Hints at remote code execution by creating arbitrary folders and mentioning code execution payloads, though the actual RCE payload is not implemented. The script uses hardcoded values and is structured as a proof-of-concept, requiring further development for weaponization. Several fingerprintable endpoints are present, including file paths within the Moodle web root and a crafted OAuth2 confirmation URL. The repository is intended for educational purposes and demonstrates the exploitation process for CVE-2023-30943.
This repository contains a combined proof-of-concept exploit for two vulnerabilities in Moodle (CVE-2023-30943): (1) Unauthenticated Arbitrary Folder Creation leading to stored XSS, and (2) Self-XSS leading to potential account takeover. The main exploit file, PoC.php, demonstrates how an attacker can create arbitrary folders on the Moodle server (e.g., under /var/www/html/localcachedir/editor_tiny/) and inject XSS payloads (such as <img src=x onerror=alert(1)>) that are executed when an administrator visits certain panels. It also crafts a malicious OAuth2 confirmation link that, if visited by a victim, triggers self-XSS and could allow account takeover. The exploit is a proof-of-concept and does not contain a full remote code execution payload, but includes placeholders for such code. The repository is structured with a single PHP exploit file and a README describing the vulnerabilities, affected versions, and usage instructions. The exploit targets specific file paths and a crafted URL endpoint within a Moodle instance, and is intended for educational and security research purposes only.
