(see SIMATIC S7-PLCSIM Advanced Function Manual V8.0, 11/2025 Section 5.3 and Section 6.1.2.3; and SIMATIC S7-PLCSIM Advanced Function Manual API V8.0, 11/2025 Section 7.2)

Risk evaluation

Mendix documentation for access rules does not adequately describe the special behavior of the System.User entity, leaving developers without sufficient guidance to configure access rules securely. This documentation gap may lead application developers to unknowingly apply overly permissive access rules to System.User, resulting in unintended exposure of sensitive user data or privilege escalation within deployed Mendix applications. A common misconfiguration identified is with the anonymous user role with a System.User entity to gain access to all stored records, even though no access rights are explicitly configured on that role. Siemens recommends Mendix developers to review their access rules based on updated documentation.

Mitigation summary

Any security model relying solely on XPath constraints on a System.User specialization to restrict access should be revised to enforce restrictions at the App Security role-management configuration level instead.

Risk evaluation

This vulnerability was privately reported relating to ABB’s implementation of the IEC 61850 communication stack for MMS client applications used in some Automation control system products. Note: IEC 61850 communication typically supports MMS and GOOSE protocols. Some ABB products support both, others only MMS (e.g. S+ Operations and PM 877). In any case, GOOSE communication is not impacted by this reported vulnerability. If an attacker gains access to a site’s IEC 61850 network, then exploiting this vulnerability will result in a device fault (PM 877, CI850 and CI868 modules) and will require a manual restart. If this attack is directed at a S+ Operations node running IEC 61850 connectivity, this will result in a crash in the IEC 61850 communication driver which, if continued a repeating basis, will also result in a denial-of-service situation. Note that this does not have an impact on the overall availability and functionality of the S+ Operations node, only the IEC 61850 communication function. The System 800xA IEC61850 Connect is not affected.
