Vigil@nce - Cisco ASR 5500: denial of service via BGP
December 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A remote and unauthenticated attacker can forge BGP packets for
Cisco ASR 5500, in order to trigger a denial of service.
Impacted products: Cisco ASR.
Severity: 2/4.
Creation date: 29/10/2015.
DESCRIPTION OF THE VULNERABILITY
The Cisco ASR product offers a BGP implementation for route
learning.
However, a lack of control of headers forces a restart of the BGP
process.
A remote and unauthenticated attacker can therefore forge BGP
packets for Cisco ASR 5500, in order to trigger a denial of
service.
