CVE-2024-39868Network attack vector

Unauthenticated VxLAN configuration access via forced browsing

Published Jul 9, 2024 · Updated Aug 27, 2025

Forced browsing in Siemens SINEMA Remote Connect Server before V3.2 SP1 allows remote attackers to read and edit VxLAN configuration. Certain VxLAN configuration actions in the web interface accept direct requests without properly validating authentication or network privileges. No login is required according to the published description; successful requests expose and permit changes to configuration for networks outside the attacker's privileges.
