CVE-2023-28175Network attack vector

Internal-network access via unrestricted SSH port forwarding

Published Jun 15, 2023 · Updated Dec 17, 2024

Improper authorization in Bosch Video Management System 7.5 through 11.1.1 allows remote authenticated users to reach trusted resources via SSH. The BVMS SSH server accepts client port-forwarding requests without restricting their destinations to resources within the BVMS scope. A valid SSH account is required; successful forwarding bypasses WAN segmentation to contact otherwise protected internal services, with confidentiality and limited integrity consequences.
