CVE-2023-26034Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized filter attribute

Published Feb 25, 2023 · Updated Mar 10, 2025

SQL injection in ZoneMinder before 1.36.33 and 1.37.0 through 1.37.32 allows remote authenticated users to execute arbitrary SQL. The events request passes the user-controlled filter attribute through Filter::sql(), and web/ajax/events.php concatenates the result into a WHERE clause without neutralizing SQL syntax. Events View or Edit permission is required; successful queries can read or modify database data and bypass application authentication or authorization.
