CVE-2021-40645Public exploitNetwork attack vector

Database disclosure via concatenated defkey SQL

Published Mar 30, 2022 · Updated Aug 4, 2024

SQL injection in glorylion JFinalOA allows remote authenticated users to read database data through a crafted defkey parameter. WorkFlowService embeds defkey directly between quotes in a dynamically built SQL string that Db.paginate sends to the database. Any ordinary logged-in account can reach the controller method and use injected SQL to retrieve database information; no data modification or service interruption is reported.
