## Overview

A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to conduct an XSS attack against a user of the interface.

This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. 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. To exploit this vulnerability, the attacker must have Admin privileges on an affected device.

## Affected

- `identity_services_engine = 2.7.0`
- `identity_services_engine = 3.0.0`
- `identity_services_engine = 3.1.0`
- `identity_services_engine = 3.2.0`
- `identity_services_engine = 3.3.0`
