## Overview

A vulnerability in the web-based management interface of Cisco Catalyst Center could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected device.

This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of the web-based management interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

## Affected

- `catalyst_center < 2.3.7.10`

## Remediation

Upgrade past the affected range:

- `catalyst_center 2.3.7.10`
