Vulnerability Summary

A vulnerability in the Cisco REST API virtual service container for Cisco IOS XE Software could allow an unauthenticated, remote malicious user to bypass authentication on the managed Cisco IOS XE device. The vulnerability is due to an improper check performed by the area of code that manages the REST API authentication service. An attacker could exploit this vulnerability by submitting malicious HTTP requests to the targeted device.

The REST API interface is not enabled by default and must be installed and activated separately on IOS XE devices. See the Details section for more information.
