Cisco NX-OS Software NX-API Cross-Site Request Forgery Vulnerability

A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.

This vulnerability is due to insufficient CSRF protections for the NX-API on an affected device. An attacker could exploit this vulnerability by persuading a user of the NX-API to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user. The attacker could view and modify the device configuration.

Note: The NX-API feature is disabled by default.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
