Citrix Issued warning to its customers to upgrade and stop a critical bug from resetting Admin Password

Citrix warns its customers to establish security updates that detect a critical Citrix Application Delivery Management’s (ADM) susceptibility to let the attackers change the admin password.

Citrix Application Delivery and Management (Citrix ADM) is a web-based solution for managing all Citric deployments including Citric ADC MPX, Citric ADC VPX, Citrix Gateway, and many others. Citrix secures Web Gateways deployed on clouds.

Florian Hauser of Code White reported a bug named CVE-2022-27511 that causes Improper Access Control weakness, by restricting the software from stopping unauthorized threat actors. Citrix ADM server and Citrix ADM agent both versions are exploited to breach security to let the threat actor corrupt systems remotely.

Citrix advises, “The impact of this can include the reset of the administrator password at the next device reboot, allowing an attacker with ssh access to construct with the default administrator credentials after the device has rebooted.”

Citrix further recommends that the compromised users can install relevant updated versions of the Citrix ADM server and Citrix ADM agent.

Citrix said, “Customers must upgrade both Citrix ADM server and all associated Citrix ADM agents.”

Citrix has also provided detailed instructions on upgrading methods of ADM servers on its documentation website.
