Descriptions

A vulnerability in the restricted shell of the Cisco Identity Services Engine (ISE) that is accessible via SSH could allow an authenticated, local attacker to run arbitrary CLI commands with elevated privileges. The vulnerability is due to incomplete input validation of the user input for CLI commands issued at the restricted shell. An attacker could exploit this vulnerability by authenticating to the targeted device and executing commands that could lead to elevated privileges. An attacker would need valid user credentials to the device to exploit this vulnerability. The vulnerability affects the following Cisco Identity Services Engine (ISE) products running Release 1.4, 2.0, 2.0.1, 2.1.0: ISE, ISE Express, ISE Virtual Appliance. Cisco Bug IDs: CSCve74916.

Una vulnerabilidad en el shell restringido de Cisco Identity Services Engine (ISE) que es accesible por SSH podría permitir que un atacante local autenticado ejecute comandos de la interfaz de línea de comandos con privilegios elevados. La vulnerabilidad se debe a la validación incompleta de los valores de entrada del usuario para los comandos de la interfaz de línea de comandos enviados al shell restringido. Un atacante podría explotar esta vulnerabilidad autenticándose en el dispositivo objetivo y ejecutando comandos que podrían conseguir privilegios elevados. Un atacante necesitaría credenciales de usuario válidas para el dispositivo para que se pueda explotar esta vulnerabilidad. La vulnerabilidad afecta a los siguientes productos de Cisco Identity Services Engine (ISE) que ejecuten la distribución 1.4, 2.0, 2.0.1 o 2.1.0: ISE, ISE Express e ISE Virtual Appliance. Cisco Bug IDs: CSCve74916.
