CVE-2023-27310Network attack vector

Privilege escalation via unchecked group assignment

Published Mar 14, 2023 · Updated Feb 27, 2025

Missing authorization in Siemens RUGGEDCOM CROSSBOW before 5.2 allows remote authenticated users to grant administrative groups. The client query handler assigns groups to user accounts without verifying that the requesting account has permission for the assignment. An authenticated account with access to the handler can elevate a non-privileged account to an administrative group and gain that group’s authority.
