"The remote Citrix ADC or Citrix Gateway device is version 12.1 before 12.1-65.35, 12.1-FIPS before 12.1-55.296,
13.0 before 13.0-90.11 or 13.1 before 13.1-45.61. It is therefore affected by multiple vulnerabilities:

  - A cross-site scripting vulnerability affecting appliances configured as a Gateway (SSL VPN, ICAS Proxy, CVPN,
    RDP Proxy) or as a AAA Virtual Server. (CVE-2023-24488)

  - An arbitrary file read vulnerability found via access to NSIP or SNIP with management interface access (CVE-2023-24487)

Please refer to advisory CTX477714 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.");
