CVE-2021-34752

Estado: AplazadaMedia (6.7)—

This vulnerability is due to insufficient validation of user-supplied command arguments. An attacker could exploit this vulnerability by submitting crafted input to the affected commands. A successful exploit could allow the attacker to execute commands with root privileges on the underlying operating system. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Detalles técnicos trazas, registros y código del informe original
A vulnerability in the CLI of Cisco FTD Software could allow an authenticated, local attacker with administrative privileges to execute arbitrary commands with root privileges on the underlying operating system of an affected device.

Esta vulnerabilidad se debe a una validación insuficiente de los argumentos de los comandos proporcionados por el usuario. Un atacante podría aprovechar esta vulnerabilidad enviando una entrada diseñada a los comandos afectados.
