Synopsis

The remote device is missing vendor-supplied security patches.

Description

The remote Cisco IOS XE device is missing vendor-supplied security patches, and is configured for Network Address Translation (NAT) and/or Multiprotocol Label Switching (MPLS). It is, therefore, affected by a flaw in the NAT and MPLS services due to improper processing of IPv4 packets. An unauthenticated, remote attacker can exploit this, via a crafted IPv4 package, to cause the device to reboot.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCut96933.
