Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

The remote Citrix ADC or Citrix Gateway device is version 11.1.x prior to 11.1-64.11, 12.1.x prior to 12.1-56.22, 13.0.x prior to 13.0-58.30. It may be, therefore, affected by a buffer overflow vulnerability in firmware for Intel(R) Ethernet 700 Series Controllers. This may allow an unauthenticated user to potentially enable an escalation of privilege via an adjacent access.

Please refer to advisory CTX263807 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.
