CVE-2022-21666Network attack vector

Database compromise via injectable user search parameters

Published Jan 10, 2022 · Updated Apr 23, 2025

SQL injection in Aaron Junker USOC before Pb2.4Bfx3 allows remote authenticated users to alter database queries through user search. The usersearch.php handler concatenates Name, Mail, or Id GET values into SELECT statements after a static, one-argument mysqli escape call. Access requires an administrative session, after which crafted search input can read or modify data available to the database account.
