## Overview

Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) guest portals could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface.&nbsp;

These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit these vulnerabilities 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 these vulnerabilities, the attacker must have&nbsp;valid administrative credentials.

## Affected

- `identity_services_engine >= 3.0.0, < 3.2`
- `identity_services_engine = 3.2.0`
- `identity_services_engine = 3.3.0`
- `identity_services_engine = 3.4.0`

## Remediation

Upgrade past the affected range:

- `identity_services_engine 3.2`
