Cisco Security Advisory: Cisco IOS and IOS XE Software Smart Install Denial of Service Vulnerability
Advisory ID: cisco-sa-20160323-smi
Revision 1.0
For Public Release 2016 March 23 16:00 GMT
+---------------------------------------------------------------------
Summary
=======
The Smart Install client feature in Cisco IOS and IOS XE Software contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to incorrect handling of image list parameters. An attacker could exploit this vulnerability by sending crafted Smart Install packets to TCP port 4786. A successful exploit could cause a Cisco Catalyst switch to reload, resulting in a DoS condition.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability other than disabling Smart Install functionality on the vulnerable device.
