TITLE

SCALANCE X-200 and SCALANCE X-200IRT Out-of-bounds write vulnerability in switch family

Trust: 0.8

sources: JVNDB: JVNDB-2020-015534

DESCRIPTION

A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.5), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0), SCALANCE X-300 switch family (incl. X408 and SIPLUS NET variants) (All versions < V4.1.0). The webserver of the affected devices contains a vulnerability that may lead to a heap overflow condition. An attacker could cause this condition on the webserver by sending specially crafted requests. This could stop the webserver temporarily. SCALANCE X-200 and SCALANCE X-200IRT An out-of-bounds write vulnerability exists in the switch family.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. SCALANCE X is a switch used to connect industrial components, such as programmable logic controllers (plc) or human machine interfaces (HMIs)
