Cross-appliance access via non-HttpOnly browser cookie

Published Oct 14, 2025 · Updated Oct 14, 2025

Security misconfiguration in SAP Cloud Appliance Library Appliances 4.0 allows remote authenticated users to access other appliances. The default S/4HANA appliance profile omits the HttpOnly attribute from a sensitive browser cookie, leaving its contents readable to client-side script. Exploitation requires high privileges and complex network interaction; successful access discloses limited application data without changing data or interrupting service.
