DESCRIPTION

A vulnerability has been identified in SCALANCE XM408-4C (All versions < V6.5), SCALANCE XM408-4C (L3 int.) (All versions < V6.5), SCALANCE XM408-8C (All versions < V6.5), SCALANCE XM408-8C (L3 int.) (All versions < V6.5), SCALANCE XM416-4C (All versions < V6.5), SCALANCE XM416-4C (L3 int.) (All versions < V6.5), SCALANCE XR524-8C, 1x230V (All versions < V6.5), SCALANCE XR524-8C, 1x230V (L3 int.) (All versions < V6.5), SCALANCE XR524-8C, 24V (All versions < V6.5), SCALANCE XR524-8C, 24V (L3 int.) (All versions < V6.5), SCALANCE XR524-8C, 2x230V (All versions < V6.5), SCALANCE XR524-8C, 2x230V (L3 int.) (All versions < V6.5), SCALANCE XR526-8C, 1x230V (All versions < V6.5), SCALANCE XR526-8C, 1x230V (L3 int.) (All versions < V6.5), SCALANCE XR526-8C, 24V (All versions < V6.5), SCALANCE XR526-8C, 24V (L3 int.) (All versions < V6.5), SCALANCE XR526-8C, 2x230V (All versions < V6.5), SCALANCE XR526-8C, 2x230V (L3 int.) (All versions < V6.5), SCALANCE XR528-6M (All versions < V6.5), SCALANCE XR528-6M (2HR2) (All versions < V6.5), SCALANCE XR528-6M (2HR2, L3 int.) (All versions < V6.5), SCALANCE XR528-6M (L3 int.) (All versions < V6.5), SCALANCE XR552-12M (All versions < V6.5), SCALANCE XR552-12M (2HR2) (All versions < V6.5), SCALANCE XR552-12M (2HR2) (All versions < V6.5), SCALANCE XR552-12M (2HR2, L3 int.) (All versions < V6.5). The OSPF protocol implementation in affected devices fails to verify the checksum and length fields in the OSPF LS Update messages. An unauthenticated remote attacker could exploit this vulnerability to cause interruptions in the network by sending specially crafted OSPF packets. Successful exploitation requires OSPF to be enabled on an affected device. SCALANCE XM-408-4C firmware, scalance xm408-4c l3 firmware, SCALANCE XM-408-8C Multiple Siemens products such as firmware contain vulnerabilities related to insufficient data integrity verification.Service operation interruption (DoS) It may be in a state. SCALANCE X switches are used to connect industrial components such as programmable logic controllers (PLCs) or human-machine interfaces (HMIs)
