CVE-2018-15368

Estado: ModificadaMedia (6.7)—

A vulnerability in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to gain access to the underlying Linux shell of an affected device and execute arbitrary commands with root privileges on the device. The vulnerability is due to the affected software improperly sanitizing command arguments to prevent modifications to the underlying Linux filesystem on a device. An attacker who has privileged EXEC mode (privilege level 15) access to an affected device could exploit this vulnerability on the device by executing CLI commands that contain crafted arguments. A successful exploit could allow the attacker to gain access to the underlying Linux shell of the affected device and execute arbitrary commands with root privileges on the device.

Un atacante que tenga acceso privilegiado en modo EXEC (nivel 15 de privilegios) a un dispositivo afectado podría explotar esta vulnerabilidad en el dispositivo ejecutando comandos CLI que contienen argumentos manipulados. Su explotación con éxito podría permitir que el atacante obtenga acceso al shell Linux subyacente del dispositivo afectado y ejecute comandos arbitrarios con privilegios root en el dispositivo."
