In short

Some versions of Cerberus DMS, Desigo CC, and SIMATIC WinCC OA rely only on client-side authentication when stronger security options are disabled, allowing attackers to impersonate users or bypass authentication entirely.

Technical detail

CWE-603: Use of Client-Side Only Authentication. When server-side authentication (SSA) and Kerberos are disabled, the affected applications authenticate users solely on the client, enabling attackers to forge authentication credentials or manipulate the client-server protocol to assume arbitrary user identities without valid credentials.
