The PAN-OS management web interface Vulnerability (CVE-2019-1566) – Jan 2019

Preface: Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side scripts into web pages viewed by other users.

Background: A WAF is deployed to protect a specific web application or set of web applications. Generally, the common attacks such as cross-site scripting (XSS) and SQL injection will be under WAF protection. But in reality, XSS is hard to avoid.

The following PAN-OS versions are affected:

PAN-OS 7.1.21 and prior
PAN-OS 8.0.14 and prior
