An improper access control vulnerability exists in the Cisco Intersight Device Connector for Nutanix Prism Central. The service exposes an API passthrough endpoint on TCP port 7373 that is accessible within the network scope of the deployment environment without authentication. An unauthenticated attacker with network access can exploit this vulnerability by sending crafted requests to the exposed endpoint to enumerate cluster metadata, including virtual machine information and cluster configuration details. While the API primarily supports read-only operations, it also allows certain cluster maintenance workflows to be invoked. Although this vulnerability does not allow persistent modification of system configurations or access to credentials or sensitive user data, successful exploitation may result in disruption of active workloads, leading to loss of service availability within the affected environment.
