UI tampering via improper authorization validation
Published Nov 14, 2023 · Updated Feb 25, 2026
Forced browsing in Siemens devices before 7.2.2 or 3.0.0 allows remote authenticated users to alter administrator-defined web interfaces. The web interface accepts certain modification requests without properly checking whether the authenticated account is authorized to perform them. Low-privileged network access is required, and the documented consequence is limited to influencing interface content configured by an administrator.
