CVE-2022-21644Network attack vector

Administrator SQL injection via unescaped search parameters

Published Jan 4, 2022 · Updated Apr 23, 2025

SQL injection in Aaron Junker USOC before Pb2.4Bfx2 allows remote authenticated users to manipulate queries through usersearch.php. The handler concatenates Name and Mail GET parameters directly inside quoted SELECT statements, so SQL metacharacters change the executed query. Only site administrators can access the search; exploitation therefore requires an administrative session, and effects remain bounded by the database account's permissions.
