Affected devices contain a vulnerability that allows an unauthenticated attacker to trigger a denial of service condition. The vulnerability can be triggered if a large amount of DCP reset packets are sent to the device.
A vulnerability has been identified in SCALANCE X-200RNA switch family (All versions < V3.2.7), SCALANCE X-300 switch family (incl. X408 and SIPLUS NET variants) (All versions < V4.1.0). Devices do not create a new unique private key after factory reset. An attacker could leverage this situation to a man-in-the-middle situation and decrypt previously captured traffic.
