Descriptions

A vulnerability in the REST API of the web-based user interface (web UI) of Cisco IOS XE 3.1 through 16.5 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. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS XE Software, if the HTTP Server feature is enabled for the device. The newly redesigned, web-based administration UI was introduced in the Denali 16.2 Release of Cisco IOS XE Software. This vulnerability does not affect the web-based administration UI in earlier releases of Cisco IOS XE Software. Cisco Bug IDs: CSCuz46036.

Una vulnerabilidad en la API REST de la interfaz de usuario web de Cisco IOS XE desde la versión 3.1 hasta la 16.5 podría permitir a un atacante remoto no autenticado omitir la autenticación de la API REST de la interfaz de usuario web del software afectado. Esta vulnerabilidad también se debe a la validación insuficiente de entrada para la API REST del software afectado. Un atacante podría explotar esta vulnerabilidad enviando una petición API maliciosa a un dispositivo afectado. Si se explota correctamente, esta vulnerabilidad podría permitir que el atacante omita la autenticación y obtenga acceso a la interfaz de usuario web del software afectado. Esta vulnerabilidad afecta a los dispositivos de Cisco que ejecuten una distribución vulnerable del software de Cisco IOS XE, si la característica HTTP Server está habilitada para el dispositivo. El nuevo diseño de la interfaz de usuario de administración web se introdujo en la distribución 16.2 de Denali del software de Cisco IOS XE. Esta vulnerabilidad no afecta a las interfaces de usuario de administración web en distribuciones anteriores del software de Cisco IOS XE. Cisco Bug IDs: CSCuz46036.
