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

high Nessus Plugin ID 99687

Language:

Synopsis

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

Description

According to its self-reported version, the Cisco IOS 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 IOS devices.

Solution

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