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-200RNA switch family (All versions < V3.2.7). Devices create a new unique key upon factory reset, except when used with C-PLUG.
