CVE-2024-39875Network attack vector

Low-privilege user and group disclosure via overbroad permissions

Published Jul 9, 2024 · Updated Aug 27, 2025

Information disclosure in Siemens SINEMA Remote Connect Server before V3.2 SP1 allows remote authenticated users to read user and group details. The Manage own remote connections permission is enforced too broadly, exposing other users' details and group memberships outside the permitted scope. Exploitation requires a low-privilege account with that permission and affects confidentiality without changing data or interrupting service.
