Cisco IOS XE EnergyWise DoS (cisco-sa-20170419-energywise)

high Nessus Plugin ID 99688


The remote device is missing a vendor-supplied security patch.


According to its self-reported version, the Cisco IOS XE software running on the remote device is affected by multiple buffer overflow conditions due to improper parsing of EnergyWise packets. An unauthenticated, remote attacker can exploit these, by sending specially crafted IPv4 EnergyWise packets to the device, to cause a denial of service condition. Note that IPv6 packets cannot be used to exploit these issues and that the EnergyWise feature is not enabled by default on Cisco XE devices.


Upgrade to the relevant fixed version referenced in Cisco Security Advisory cisco-sa-20170419-energywise.
