Synopsis

The remote device is affected by multiple vulnerabilities.

Description

The remote Citrix ADC or Citrix NetScaler Gateway device is version 11.1.x prior to 11.1-65.20, 12.1.x prior to 12.1-62.23, 12.1-FIPS prior to 12.1-55.238 or 13.0.x prior to 13.0-82.41. It is, therefore, affected by multiple vulnerabilities:

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

Solution

For versions 11.1.x, 12.1.x, 12.1-FIPS and 13.0.x, upgrade to 11.1-65.20, 12.1-62.23, 12.1-55.238-FIPS and 13.0-82.41, or later, respectively.
