CVE-2023-3621Public exploitNetwork attack vector

Database manipulation via concatenated article identifiers

Published Jul 11, 2023 · Updated Aug 2, 2024

SQL injection in IBOS OA 4.5.5 allows remote authenticated users to alter database queries through the Delete Packet endpoint. The delete action passes the POST-supplied articleids value into deleteByRelateid, where query conditions are concatenated before createDeleteCommand executes SQL. Access to the administration background is required, and successful injection can read or modify application database data.
