## Overview

A stored cross-site scripting (XSS) vulnerability may allow an authenticated, high-privilege administrator to store malicious content in a configuration. The content may execute in another authenticated user's browser when that user views or compares the affected configuration. Successful exploitation may allow the attacker to act through the victim's authenticated browser session to access sensitive data, modify configurations, or disrupt managed wireless services.
