A vulnerability in the Ultra Automation Service (UAS) of the Cisco Ultra Services Framework could allow an unauthenticated, remote attacker to gain unauthorized access to a targeted device.

The vulnerability is due to an insecure default configuration of the Apache ZooKeeper service used by the affected software. An attacker could exploit this vulnerability by accessing the affected device through the orchestrator network. An exploit could allow the attacker to gain access to ZooKeeper data nodes (znodes) and influence the behavior of the system’s high-availability feature.
