A vulnerability in the implementation of Common Industrial Protocol (CIP) functionality in Cisco Industrial Ethernet 2000 Series Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to a system memory leak. The vulnerability is due to improper handling of malformed CIP packets. An attacker could exploit this vulnerability by sending malformed CIP requests to a targeted device. A successful exploit could allow the attacker to cause a DoS condition on the targeted device due to low system memory. There are no workarounds that address this vulnerability.
