A vulnerability in the web-based management interface of Cisco IOS XE New Generation Wireless Controller (NGWC) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device.
The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on an affected device by using a web browser and with the privileges of the user.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Fixed Releases
Cisco IOS XE Software
To help customers determine their exposure to vulnerabilities in Cisco IOS XE Software, Cisco provides a tool, the Cisco IOS Software Checker, that identifies any Cisco Security Advisories that impact a specific Cisco IOS XE Software release and the earliest release that fixes the vulnerabilities described in each advisory (“First Fixed”). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities described in all the advisories identified (“Combined First Fixed”).
Customers can use this tool to perform the following tasks:
- Initiate a search by choosing one or more releases from a drop-down menu or uploading a file from a local system for the tool to parse
- Enter the output of the show version command for the tool to parse
- Create a custom search by including all previously published Cisco Security Advisories, a specific advisory, or all advisories in the most recent bundled publication
To determine whether a release is affected by any published Cisco Security Advisory, use the Cisco IOS Software Checker on Cisco.com or enter a Cisco IOS XE Software release—for example, 3.17.0S—in the following field:
-
