CVE-2022-32257Network attack vector

Unauthenticated resource access via unprotected web endpoints

Published Mar 12, 2024 · Updated Aug 3, 2024

Improper access control in Siemens SINEMA Remote Connect Server before 3.2 allows remote attackers to access resources through web endpoints. The web service exposes some endpoints without enforcing required authorization checks; Siemens has not identified the endpoints or disclosed the faulty code path. No authentication or user interaction is required, and the documented consequence extends from unauthorized resource access to code execution.
