Symptoms or Error

After applying the mitigation steps, the vulnerability still exists. 

Solution

Perform the following steps:

Citrix recommends that customers update to the 12.1 build 50.28/50.31 or later for the mitigation steps to function as intended.
  2. Review the workaround steps and ensure save config is applied, especially before the reboot.
