Description

The affected versions of S+ Operations (version 2.1 SP1 and earlier) used an approach for user authentication which relies on validation at the client node (client-side authentication). This is not as secure as having the server validate a client application before allowing a connection. Therefore, if the network communication or endpoints for these applications are not protected, unauthorized actors can bypass authentication and make unauthorized connections to the server application.

Affected configurations

• abb symphony \+ historian 3.0 • abb symphony \+ historian 3.1 • abb symphony \+ operations 1.1 • abb symphony \+ operations 2.0 • abb symphony \+ operations 2.1 • abb symphony \+ operations 3.0 • abb symphony \+ operations 3.1 • abb symphony \+ operations 3.2 • abb symphony \+ operations 3.3
