CISA's summary
Summary: Desigo CC and Cerberus DMS are based on SIMATIC WinCC OA and implement client-side only authentication for specific parts of their client-server communication. In this configuration, attackers could impersonate other users or exploit the client-server protocol without being authenticated, as documented for SIMATIC WinCC OA in SSA-111512 [1]. Siemens recommends specific mitigations, documented in [2], for products where fixes are not, or not yet available. Additional details regarding these mitigations can be found in the chapter Additional Information.
