June 2017 by Vigil@nce
This bulletin was written by Vigil@nce : https://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An authenticated attacker can send malicious SNMP packets to a
device running Cisco IOS XE, in order to trigger a denial of
service.
Impacted products: Cisco Catalyst, IOS by Cisco, IOS XE Cisco,
Cisco Router.
Severity: 2/4.
Creation date: 20/04/2017.
Revision date: 10/05/2017.
DESCRIPTION OF THE VULNERABILITY
The Cisco IOS and IOS XE products have a service to manage
received SNMP packets.
However, when malicious SNMP packets are received, a fatal error
then a device reboot occurs.
An authenticated attacker can therefore send malicious SNMP
packets to a device running Cisco IOS XE, in order to trigger a
denial of service.
