Detail

A vulnerability in the REST API of the web-based user interface (web UI) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass authentication to the REST API of the web UI of the affected software.

The vulnerability is due to insufficient input validation for the REST API of the affected software. An attacker could exploit this vulnerability by sending a malicious API request to an affected device. A successful exploit could allow the attacker to bypass authentication and gain access to the web UI of the affected software.

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