CVE-2025-42978

Insufficiently Secure Hostname Verification for Outbound TLS Connections in SAP NetWeaver Application Server Java



Description

The widely used component that establishes outbound TLS connections in SAP NetWeaver Application Server Java does not reliably match the hostname that is used for the connection against the wildcard hostname defined in the received certificate of remote TLS server. This might lead to the outbound connection being established to a possibly malicious remote TLS server and hence disclose information. Integrity and Availability are not impacted.
