CVE-2023-35132Network attack vector

Authenticated SQL injection

Published Jun 22, 2023 · Updated Aug 2, 2024

SQL injection in Moodle LMS 4.2.0 and earlier allows remote authenticated users to read or alter data via the MNet SSO access control page. Moodle has not published the vulnerable parameter, query construction, or input-neutralization failure within that administrative page. Reaching the page requires a low-privileged authenticated account, and successful injection can affect database confidentiality, integrity, and availability.
