Cisco Security Advisory: Cisco IOS XE Software Web User Interface Denial of Service Vulnerability
Advisory ID: cisco-sa-20170322-webui
For Public Release: 2017 March 22 16:00 GMT
Last Updated: 2017 March 22 16:00 GMT
CVE ID(s): CVE-2017-3856
CVSS Score v(3): 8.6 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
A vulnerability in the web user interface of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload.
The vulnerability is due to insufficient resource handling by the affected software when the web user interface is under a high load. An attacker could exploit this vulnerability by sending a high number of requests to the web user interface of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.
To exploit this vulnerability, the attacker must have access to the management interface of the affected software, which is typically connected to a restricted management network.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
