Citrix Application Delivery Management Unauthorized Access Vulnerability

Risk:
High
Date Discovered:
08 October 2019
Description:
Citrix Application Delivery Management is prone to an unauthorized-access vulnerability. Attackers can exploit this issue to gain unauthorized access to the affected application and gain elevated privileges. The following products of Citrix are affected: Citrix Application Delivery Management prior to version 12.1 build 54.13 are vulnerable. Citrix Application Delivery Management Cloud prior to version 13.0 build 41.20 are vulnerable.
Technologies Affected
  • Citrix Application Delivery Management 12.1 Build 53.12
  • Citrix Application Delivery Management 13.0
Recommendations
  • Block external access at the network boundary, unless external parties require service.
    If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.
  • Run all software as a nonprivileged user with minimal access rights.
    Run all non-administrative software as a non-administrative user with the least amount of privileges required to successfully operate. This will greatly reduce the potential damage that successful exploitation may achieve.
  • Deploy network intrusion detection systems to monitor network traffic for malicious activity.
    Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review logs regularly.
Updates are available. Please see the references or vendor advisory for more information.
