Descriptions

A vulnerability in the web framework of Cisco IOS XE Software could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient input validation of HTTP parameters supplied by the user. An attacker could exploit this vulnerability by authenticating to the device and submitting crafted input to the affected web page parameter. The user must be authenticated to access the affected parameter. A successful exploit could allow the attacker to execute commands with root privileges. This vulnerability affects Cisco devices running Cisco IOS XE Software Release 16.2.1, if the HTTP Server feature is enabled for the device. The newly redesigned, web-based administration interface was introduced in the Denali 16.2 Release of Cisco IOS XE Software. The web-based administration interface in earlier releases of Cisco IOS XE Software is not affected by this vulnerability. Cisco Bug IDs: CSCuy83069.

Una vulnerabilidad en el framework de la web de Cisco IOS XE Software podrá permitir a un atacante remoto no autenticado inyectar comandos arbitrarios que se ejecutan con privilegios de root. La vulnerabilidad se debe a la insuficiente validación de entrada de los parámetros HTTP suministrados por el usuario. Un atacante podría explotar esta vulnerabilidad al autenticarse en el dispositivo y enviar la entrada creada al parámetro de página web afectado. El usuario debe estar autenticado para acceder al parámetro afectado. Una explotación exitosa podría permitir al atacante ejecutar comandos con privilegios de root. Esta vulnerabilidad afecta a los dispositivos Cisco que ejecutan Cisco IOS XE Software versión 16.2.1, si la característica de servidor HTTP está habilitada para el dispositivo. La nueva interfaz rediseñada de administración basada en web fue introducida en la versión 16.2 de Denali del software Cisco IOS XE.
