CVE-2022-0332Network attack vector

Authenticated SQL injection via unsanitized sort order

Published Jan 25, 2022 · Updated Aug 2, 2024

SQL injection in Moodle LMS 3.11 through 3.11.4 allows remote authenticated users to manipulate queries through the H5P attempts service. The get_user_attempts external method accepts sortorder as text and appends it directly to the user query's ORDER BY clause without an allowlist. Exploitation requires the h5pactivity:reviewattempts capability; successful requests alter the query executed while attempt data is fetched.
