CVE-2019-1833

A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocol parser of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured policies. The vulnerability is due to improper parsing of specific attributes in a TLS packet header. An attacker could exploit this vulnerability by sending malicious TLS messages to the affected system. A successful exploit could allow the attacker to bypass the configured policies for the system, which could allow traffic to flow through without being inspected.

Una vulnerabilidad en Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocol parser of Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autorizado omitir las políticas configuradas. La vulnerabilidad es debido a un análisis incorrecto de atributos específicos en un encabezado de paquete TLS. Un atacante podría explotar esta vulnerabilidad enviando mensajes TLS maliciosos al sistema afectado. Una explotación exito podría permitir al atacante eludir las políticas configuradas para el sistema, lo que podría permitir que el tráfico fluya sin ser inspeccionado.
