Citrix Issues Patches for Critical Flaw Affecting ADC and Gateway Products

Citrix has released security updates to address a critical authentication bypass flaw in the application delivery controller and Gateway that could be exploited to take control of affected systems.

Successful exploitation of the issues could enable an adversary to gain authorized access, perform remote desktop takeover, and even circumvent defenses against login brute-force attempts under specific configurations.

The following supported versions of Citrix ADC and Citrix Gateway are affected by the flaws -.

The cloud computing and virtualization technology company said that no action is required from customers relying on cloud services managed directly by Citrix.

Jarosław Jahrek Kamiński, a researcher at Polish penetration testing firm Securitum, has been credited with discovering and reporting the vulnerabilities.

“Affected customers of Citrix ADC and Citrix Gateway are recommended to install the relevant updated versions of Citrix ADC or Citrix Gateway as soon as possible,” Citrix said in an advisory.
