Descriptions

A vulnerability in the SNORT detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to bypass a file policy that is configured to block the Server Message Block Version 2 (SMB2) protocol. The vulnerability is due to the incorrect detection of an SMB2 file when the detection is based on the length of the file. An attacker could exploit this vulnerability by sending a crafted SMB2 transfer request through the targeted device. A successful exploit could allow the attacker to bypass filters that are configured to block SMB2 traffic. Cisco Bug IDs: CSCve58398.

Una vulnerabilidad en el motor de detección SNORT de Cisco Firepower System Software podría permitir que un atacante remoto sin autenticar omita una política de archivos que esté configurada para bloquear el protocolo Server Message Block Version 2 (SMB2). La vulnerabilidad se debe a la incorrecta detección de un archivo SMB2 cuando la detección se basa en la longitud del archivo. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición de transferencia de SMB2 manipulada al dispositivo objetivo. Un exploit con éxito podría permitir que el atacante omita filtros que están configurados para bloquear el tráfico SMB2. Cisco Bug IDs: CSCve58398.
