CVE-2025-42996Network attack vector

Unauthenticated client-session takeover via undisclosed mechanism

Published Jun 10, 2025 · Updated Jun 10, 2025

Insecure session management in SAP NetWeaver MDM Server MDM_SERVER 710.750 allows remote attackers to take over client sessions. SAP has not published the faulty code locus or operation that permits one client to assume an existing session without re-authentication. Exploitation requires an existing client session and a high-complexity network attack; successful use exposes or modifies non-sensitive data and can degrade server performance through resource consumption.
