Critical (9.8) in siemens. EPSS 1.7% chance of exploitation in the next 30 days.
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.
