Vulnerabilities have been discovered in Citrix Application Delivery Management (Citrix ADM) that, if exploited, could result in the following security issues: 

• Corruption of the system by a remote, unauthenticated user. The impact of this can include the reset of the administrator password at the next device reboot, allowing an attacker with ssh access to connect with the default administrator credentials after the device has rebooted. 

• Temporary disruption of the ADM license service. The impact of this includes preventing new licenses from being issued or renewed by Citrix ADM.

Mitigating Factors

Citrix strongly recommends that network traffic to the Citrix ADM’s IP address is segmented, either physically or logically, from standard network traffic. Doing so diminishes the risk of exploitation of these issues.
