According to its self-reported version, the Cisco IOS software running on the remote device is affected by a denial of service vulnerability in its Layer 2 Tunneling Protocol (L2TP) parsing function due to insufficient validation of L2TP packets. An unauthenticated, remote attacker can exploit this issue, via a specially crafted L2TP packet, to cause the device to reload.

Note that this issue only affects devices if the L2TP feature is enabled and the device is configured as an L2TP Version 2 (L2TPv2) or L2TP Version 3 (L2TPv3) endpoint. By default, the L2TP feature is not enabled.
