  • SSA-111512SSA-111512: Client-side Authentication in SIMATIC WinCC OA2022-06-21csaf · siemens_psirtDE

    SIMATIC WinCC OA implements client-side only authentication, when neither server-side authentication (SSA) nor Kerberos authentication is enabled. In this configuration, attackers could impersonate other users or exploit the client-server protocol without being authenticated. Siemens recommends to enable server-side authentication (SSA) or Kerberos authentication for all WinCC OA projects, as documented in the WinCC OA Security Guideline. In SIMATIC WinCC OA server-side authentication is available since V3.15 (and offered as the default configuration since V3.17). Additional information can be found at: https://cert-portal.siemens.com/productcert/news.html?id=21.

  • SSA-836027SSA-836027: Client-side Authentication in Desigo CC and Cerberus DMS2022-10-11csaf · siemens_psirtDE

    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.
