Descriptions

A vulnerability in specific CLI commands for the Cisco Identity Services Engine could allow an authenticated, local attacker to cause a denial of service (DoS) condition. The device may need to be manually rebooted to recover. The vulnerability is due to lack of proper input validation of the CLI user input for certain CLI commands. An attacker could exploit this vulnerability by authenticating to the device and issuing a crafted, malicious CLI command on the targeted device. A successful exploit could allow the attacker to cause a DoS condition. The attacker must have valid administrative privileges on the device to exploit this vulnerability. Cisco Bug IDs: CSCvf63414, CSCvh51992.

Una vulnerabilidad en determinados comandos de la interfaz de línea de comandos (CLI) para Cisco Identity Services Engine podría permitir que un atacante local autenticado provoque una denegación de servicio (DoS). El dispositivo podría necesitar volver a cargarse manualmente para que se recupere. La vulnerabilidad se debe a una falta de medidas correctas de validación de los valores de entrada del usuario CLI para determinados comandos CLI. Un atacante podría explotar esta vulnerabilidad autenticándose en el dispositivo y enviando un comando CLI malicioso manipulado en el dispositivo objetivo. Su explotación con éxito podría permitir que el atacante provoque una condición de denegación de servicio (DoS). El atacante tiene que tener privilegios de administrador válidos en el dispositivo para explotar esta vulnerabilidad. Cisco Bug IDs: CSCvf63414, CSCvh51992.
