CVE-2023-33509Public exploitNetwork attack vector

Unauthenticated file and database disclosure via SQL injection

Published May 31, 2023 · Updated Jan 10, 2025

SQL injection in KramerAV VIA GO² before 4.0.1.1326 allows remote attackers to read device files and database data via HTTPS. The downloadMedia.php handler passes the unauthenticated medId query parameter into a MySQL query without neutralizing SQL syntax, enabling UNION-based file reads. No account is required; exposed devices can disclose arbitrary local files and stored user passwords, which can support complete device compromise when chained with separate flaws.
