The vulnerability is due to incorrect detection of modified HTTP packets used in chunked responses. An attacker could exploit this vulnerability by sending crafted HTTP packets through an affected device. A successful exploit could allow the attacker to bypass a configured File Policy for HTTP packets and deliver a malicious payload."},{"lang":"es","value":"Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección de Snort que podría permitir a un atacante remoto no autenticado omitir una Política de Archivos configurada para HTTP. La vulnerabilidad es debido a una detección incorrecta de paquetes HTTP modificados utilizados en respuestas fragmentadas. Un atacante podría explotar esta vulnerabilidad mediante el envío de paquetes HTTP diseñados a través de un
