CVE-2022-31788Public exploitNetwork attack vector

Unauthenticated SQL injection via ClassID parameter

Published Jun 10, 2022 · Updated Aug 3, 2024

SQL injection in IdeaLMS 2022 allows remote attackers to alter database queries through a crafted ClassID URL parameter. The ClassAccessControl endpoint accepts SQL syntax in ClassID, and a time-delay expression changes database execution without returning query results. The HTTP request requires no authentication; the published proof of concept demonstrates blind query control through a delayed response, not specific data access.
