Loading vulnerability…
CVE-2022-30600 is a logic flaw in Moodle's failed-login attempt counting mechanism. Due to incorrect calculation of failed authentication attempts, the application may fail to increment or evaluate the counter correctly, allowing the configured account lockout threshold to be bypassed. As a result, Moodle's intended protection against repeated authentication failures is not reliably enforced.

This repository provides a proof-of-concept exploit for CVE-2022-30600, a vulnerability in Moodle (versions 3.9-3.9.13, 3.10-3.10.10, 3.11-3.11.6) that allows bypassing the account lockout threshold by sending concurrent login requests. The repository contains two main exploit files: 'poc.py' (Python) and 'poc.cpp' (C++). Both scripts automate brute-force attacks against the Moodle login endpoint by sending multiple concurrent login attempts using a supplied wordlist and targeting a specific username. The C++ version is recommended for higher performance due to better threading support. The exploit requires the attacker to specify the target Moodle URL, username, wordlist, number of threads, and number of attempts. The README provides detailed usage instructions, example commands, and describes the underlying vulnerability. The main attack vector is network-based, targeting the Moodle web application's login endpoint. No fake or detection-only scripts are present; both code files implement the exploit logic.
