Vigil@nce - Cisco ISR: denial of service via VPN

May 2013 by Vigil@nce

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

SYNTHESIS OF THE VULNERABILITY

An authenticated attacker can open several VPN tunnels on Cisco
Aggregation Services Router Route Processor 2, in order to trigger
a denial of service.

 Impacted products: IOS
 Severity: 1/4
 Creation date: 13/05/2013

DESCRIPTION OF THE VULNERABILITY

An authenticated user can display encryption statistics.

However, if several tunnels are open, this operation stops the
Route Processor.

An authenticated attacker can therefore open several VPN tunnels
on Cisco Aggregation Services Router Route Processor 2, in order
to trigger a denial of service.
