Cisco Nexus 9000 Series ACI Mode Switch ICMP Record Route Vulnerability

Advisory ID: cisco-sa-20160203-n9knci

Revision 1.0

For Public Release 2016 February 3 16:00 UTC (GMT)

+———————————————————————

Summary
=======

A vulnerability in the ICMP implementation in the Cisco Nexus 9000
Series Application Centric Infrastructure (ACI) Mode Switch could
allow an unauthenticated, remote attacker to cause the switch to
reload, resulting in a denial of service (DoS) condition.

The vulnerability is due to improper handling of an ICMP packet with
the IPv4 Type 7 option for record route. An attacker could exploit
this vulnerability by sending an ICMP packet with the record route
option to an interface on the affected switch. An exploit could allow
the attacker to cause a DoS condition because the switch will reload
each time the ICMP packet is received.

Cisco has released software updates that address this vulnerability.
A workaround that addresses this vulnerability is available.
