The remote NetScaler ADC (formerly Citrix ADC) or NetScaler Gateway (formerly Citrix Gateway) device is version 12.1, 12.1-FIPS before 12.1-55.302-FIPS, 13.0 before 13.0-92.21, 13.1 before 13.1-51.15, 13.1-FIPS before 13.1-37.176-FIPS, or 14.1 before 14.1-12.35. It is, therefore, affected by multiple vulnerabilities:
Authenticated (low privileged) remote code execution on Management Interface (CVE-2023-6548)
Denial of Service (CVE-2023-6549)
Please refer to advisory CTX584986 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.
