CVE-2023-34477Network attack vector

Unauthenticated database compromise

Published Aug 7, 2023 · Updated Oct 20, 2024

SQL injection in BrainCert Virtual Classroom Joomla Component 1.0.0 through 1.25.0 allows remote attackers to alter database queries. The Joomla CNA record does not identify the affected request parameter, code path, or SQL statement, so the precise input-to-query operation is undisclosed. No authentication or user interaction is required; successful injection can read, modify, or delete application data and interrupt service.
