Cisco Issues Hight Alert on IPv6 Vulnerability, Says It Affects Both Cisco and Other Products

Cisco today released a high-level alert warning about a vulnerability in IPv6 packet processing functions of multiple Cisco products that could allow an unauthenticated, remote attacker to cause an affected device to stop processing IPv6 traffic, leading to a denial of service (DoS) condition on the device.

Cisco states: “The vulnerability is due to insufficient processing logic for crafted IPv6 packets that are sent to an affected device. An attacker could exploit this vulnerability by sending crafted IPv6 Neighbor Discovery packets to an affected device for processing. A successful exploit could allow the attacker to cause the device to stop processing IPv6 traffic, leading to a DoS condition on the device.”

The company has also pointed out that the vulnerability is not Cisco specific and any IPv6 processing unit not capable of dropping such packets early in the processing path or in hardware is affected by this vulnerability.

There are no workarounds that address this vulnerability as of yet and customers are advised to rely on external mitigation techniques.
