description

SIMATIC BATCH V9.1 and the other listed SIMATIC products can accept NTLM authentication in a way that permits credential relay. An unauthenticated attacker positioned between communicating systems may impersonate a legitimate user to reachable services. The resulting access depends on which NTLM-enabled services are exposed.

mitigation

Upgrade SIMATIC BATCH V9.1 to *; SIMATIC Information Server 2020 to *; SIMATIC Information Server 2022 to *; SIMATIC PCS 7 V9.1 to *; SIMATIC Process Historian 2020 to *; SIMATIC Process Historian 2022 to *; SIMATIC WinCC Runtime Professional V17 to *; SIMATIC WinCC Runtime Professional V18 to *; SIMATIC WinCC Runtime Professional V19 to *; SIMATIC WinCC Runtime Professional V20 to *; SIMATIC WinCC Runtime Professional V21 to *; SIMATIC WinCC V7.5 to *; SIMATIC WinCC V8.0 to *; SIMATIC WinCC V8.1 to * or later.
