CVE-2020-24683

Severity CVSS v4.0:
Pending analysis
Type:
CWE-669 Incorrect Resource Transfer Between Spheres
Publication date:

Last modified:

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.
