Vigil@nce - Cisco IOS, IOS XE: denial of service via BGP

September 2016 by Vigil@nce

This bulletin was written by Vigil@nce : https://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

An attacker can send crafted BGP packets to a Cisco IOS or IOS XE
equipment, in order to trigger a denial of service.

Impacted products: IOS by Cisco, IOS XE Cisco, Cisco Router.

Severity: 2/4.

Creation date: 18/07/2016.

DESCRIPTION OF THE VULNERABILITY

The Cisco IOS or IOS XE product offers the BGP protocol to
exchange network routes with neighbour routers.

However, in certain cases an implementation error generates a
fatal error via BGP.

An attacker can therefore send crafted BGP packets to a Cisco IOS
or IOS XE equipment, in order to trigger a denial of service.
