## Overview

Multiple vulnerabilities in the WebVPN service of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the WebVPN portal of an affected device. The vulnerabilities exist because the software insufficiently validates user-supplied input on an affected device. An attacker could exploit these vulnerabilities by persuading a user of the 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. An attacker would need administrator privileges on the device to exploit these vulnerabilities.

## Affected

- `adaptive_security_appliance_software < 9.4.4.34`
- `adaptive_security_appliance_software >= 9.5, < 9.6.4.25`
- `adaptive_security_appliance_software >= 9.7, < 9.8.4`
- `adaptive_security_appliance_software >= 9.9, < 9.9.2.50`
- `adaptive_security_appliance_software >= 9.10, < 9.10.1.17`
- `secure_firewall_threat_defense >= 6.2.1, < 6.2.3.12`
- `secure_firewall_threat_defense >= 6.3.0, < 6.3.0.3`

## Remediation

Upgrade past the affected range:

- `adaptive_security_appliance_software 9.10.1.17`
- `secure_firewall_threat_defense 6.3.0.3`
