CVE-2012-6438
high · 7.5The device does not properly validate the data being sent to the buffer. An attacker can send a malformed CIP packet to Port 2222/TCP, Port 2222/UDP, Port 44818/TCP, or Port 44818/UDP, which creates a buffer overflow and causes the NIC to crash. Successful exploitation of this vulnerability could cause loss of availability and a disruption in communications with other connected devices.
