Descriptions

In Stormshield Network Security (SNS) before 3.7.25, 3.8.x through 3.11.x before 3.11.13, 4.x before 4.2.10, and 4.3.x before 4.3.5, a flood of connections to the SSLVPN service might lead to saturation of the loopback interface. This could result in the blocking of almost all network traffic, making the firewall unreachable. An attacker could exploit this via forged and properly timed traffic to cause a denial of service.

En Stormshield Network Security (SNS) antes de la versión 3.7.25, de la 3.8.x a la 3.11.x antes de la 3.11.13, de la 4.x antes de la 4.2.10 y de la 4.3.x antes de la 4.3.5, una avalancha de conexiones al servicio SSLVPN podría provocar la saturación de la interfaz de loopback. Esto podría resultar en el bloqueo de casi todo el tráfico de red, haciendo que el firewall sea inalcanzable. Un atacante podría explotar esto a través de un tráfico falsificado y debidamente cronometrado para causar una denegación de servicio
