Cisco Small Business 220 Series Smart Plus Switches Web Interface Cross-Site Request Forgery Vulnerability

A vulnerability in the web-based management interface of Cisco Small Business 220 Series Smart Plus (Sx220) Switches 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 an affected device. 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 a targeted device via a web browser and with the privileges of the user.

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