The remote device may be affected by multiple vulnerabilities.

- An unauthenticated remote code execution affecting appliances configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server. (CVE-2023-3519)

- A reflected cross-site scripting vulnerability that requires victim to access an attacker-controlled link in the browser while being on a network with connectivity to the NSIP (CVE-2023-3466)

- A Privilege Escalation to root administrator (nsroot) given authenticated access to NSIP or SNIP with management interface access (CVE-2023-3467)

Please refer to advisory CTX561482 for more information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
