Unauthenticated access via HTTPS endpoint authentication bypass
Published Feb 10, 2025 · Updated Feb 10, 2025
Authentication bypass in the OPC UA .NET Standard Stack before 1.5.374.158 allows remote attackers to access protected HTTPS endpoints. The bulletin does not identify the HTTPS binding operation that skips application authentication; it establishes only that the flaw affects enabled HTTPS endpoints using a security policy other than None. Reachability requires network access to that endpoint configuration; exploitation exposes protected data and permits limited unauthorized changes.
