CVE-2019-12693

A vulnerability in the Secure Copy (SCP) feature of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to the use of an incorrect data type for a length variable. An attacker could exploit this vulnerability by initiating the transfer of a large file to an affected device via SCP. To exploit this vulnerability, the attacker would need to have valid privilege level 15 credentials on the affected device. A successful exploit could allow the attacker to cause the length variable to roll over, which could cause the affected device to crash.

Una vulnerabilidad en la funcionalidad Secure Copy (SCP) del Software Cisco Adaptive Security Appliance (ASA), podría permitir a un atacante remoto autenticado causar una condición de denegación de servicio (DoS). La vulnerabilidad es debido al uso de un tipo de datos incorrecto para una variable de longitud. Un atacante podría explotar esta vulnerabilidad mediante el inicio de la transferencia de un archivo grande a un dispositivo afectado por medio de SCP. Para explotar esta vulnerabilidad, el atacante necesitaría tener credenciales válidas de nivel de privilegio 15 sobre el dispositivo afectado. Una explotación con éxito podría permitir que el atacante haga que la variable de longitud se desplace, lo que podría causar que el dispositivo afectado se bloquee.
