Summary
A vulnerability has been identified in SIMATIC CP 442-1 RNA (All versions < V1.5.18), SIMATIC CP 443-1 RNA (All versions < V1.5.18). The affected devices improperly handles excessive ARP broadcast requests. This could allow an attacker to create a denial of service condition by performing ARP storming attacks, which can cause the device to reboot.
