CVE-2025-42895

Unauthorized code loading via crafted connection properties

Published Nov 11, 2025 · Updated Nov 12, 2025

Code injection in SAP HANA JDBC Client HDB_CLIENT 2.0 allows local users to load unauthorized code through crafted connection properties. The client insufficiently validates supplied connection-property values before passing them into a code-loading path. Exploitation requires high-privilege local authentication and user interaction; SAP does not disclose whether the major availability loss is a hang or crash.
