The remote Citrix SD-WAN Center is version 10.2.x prior to 10.2.9a, 11.1.x prior to 11.1.2c, 11.2.x prior to 11.2.3a, or 11.2.x prior to 11.3.1a. It is, therefore, vulnerable to a Network-based denial-of-service from an attacker within the same Layer 2 network segment.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
