CVE-2026-5944

Cisco Intersight Device Connector for Nutanix Prism Central Unauthenticated API Access

Published Apr 28, 2026 CVSS 4.0 · 6.7 Medium EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Solution

Nutanix has released version 7.5.1 of the Cisco Intersight Device Connector: * Log in to Prism Central (PC) and navigate to the Life Cycle Manager (LCM) Dashboard. * Click "Perform Inventory" or "Get Full Inventory" to refresh the inventory. * After the inventory refresh completes, navigate to the Marketplace. * Select the Cisco Intersight Device Connector. * Click "Upgrade" to update to version 7.5.1 or later.


Vendor Workaround

If upgrading the Cisco Intersight Device Connector to version 7.5.1 or later is not immediately possible, restrict access to TCP port 7373 by limiting the service to internal traffic only: * Establish an SSH session to Prism Central (PC). * Execute the following command to reconfigure the service visibility to internal traffic only: sudo kubectl -n pc-platform-other annotate service cisco-device-connector service.msp.ntnx.io/lb=pc-internal --overwrite * Run the following command: sudo kubectl get svc -n pc-platform-other and verify that the Cisco Intersight Device Connector is no longer associated with the Prism Central public IP address.
