| Package | Affected versions | Patched versions |
|---|---|---|
| symphony + historian | = 3.0= 3.1 | |
| symphony + operations | = 1.1= 2.0= 2.1= 3.0= 3.1= 3.2= 3.3 |
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.
