Cisco Security Advisory: Cisco IOx Data in Motion Stack Overflow Vulnerability

Advisory ID: cisco-sa-20170322-iox

Revision: 1.0

For Public Release: 2017 March 22 16:00 GMT

Last Updated: 2017 March 22 16:00 GMT

CVE ID(s): CVE-2017-3853

CVSS Score v(3): 9.8 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

+---------------------------------------------------------------------

Summary
=======
A vulnerability in the Data-in-Motion (DMo) process installed with the Cisco IOx \
application environment could allow an unauthenticated, remote attacker to cause a \
stack overflow that could allow remote code execution with root privileges in the \
virtual instance running on an affected device.

The vulnerability is due to insufficient bounds checking in the DMo process. An \
attacker could exploit this vulnerability by sending crafted packets that are \
forwarded to the DMo process for evaluation. The impacts of a successful exploit are \
limited to the scope of the virtual instance and do not impact the router that is \
hosting Cisco IOx.

Cisco has released software updates that address this vulnerability. There are no \
workarounds that address this vulnerability.
