Summary

A vulnerability has been identified in RFID 181EIP (All versions), RUGGEDCOM Win (V4.4, V4.5, V5.0, and V5.1), SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.3), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.4.1), SCALANCE X-200RNA switch family (All versions < V3.2.6), SCALANCE X-300 switch family (incl. SIPLUS NET variants) (All versions < V4.1.3), SCALANCE X408 (All versions < V4.1.3), SCALANCE X414 (All versions), SIMATIC RF182C (All versions). Unprivileged remote attackers located in the same local network segment (OSI Layer 2) could gain remote code execution on the affected products by sending a specially crafted DHCP response to a client's DHCP request.
