A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (Versions < V5.0.0 for CVE-2013-3633 and versions < V4.5.0 for CVE-2013-3634), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.1.0). The implementation of SNMPv3 does not check the user credentials sufficiently. Therefore, an attacker is able to execute SNMP commands without correct credentials.
