CVE-2022-44069 Zenario CMS 9.3.57186 is vulnerable to Cross Site Scripting (XSS) via the Nest library module.

CVE-2022-44069 Zenario CMS 9.3.57186 is vulnerable to Cross Site Scripting (XSS) via the Nest library module.

XSS is a vulnerability in which malicious code is injected into otherwise innocuous web applications, causing a host of security issues. In order to exploit a XSS vulnerability, a hacker must send a message to a vulnerable application that accepts input. For example, if a site shows a list of stock prices, and the user can input the price of a product they wish to purchase. An attacker must find a way to send malicious code to the application so that it can accept the input, and cause the application to do something it wasn’t designed to do. The best way to exploit a XSS vulnerability is to send an email to the hacker. In this example, the hacker would send an email to the website that displayed the list of prices. The hacker would then send a message to the website that displayed the list of prices that has malicious code within it. The hacker would need to find a website that hosts a list of stock prices.

What is XSS?

XSS is an acronym that stands for Cross-Site Scripting. The "cross site" part of the acronym means that the malicious code actually runs on a different website than the one displaying the list of prices. With XSS, hackers can inject malicious code into otherwise innocuous websites and content.
For example, consider a regular website that hosts information about movies. In this scenario, if a hacker wanted to send a message to the website's visitor saying "I'm going to infect you," they would need to find a way to send that message via email as well as crack their way in and insert their malicious code into the movies webpage.
The best way to exploit a XSS vulnerability is by sending an email message with malicious code in it. With XSS vulnerabilities, hackers must send an email to the vulnerable website or app so that it can accept input from them and redirect it somewhere else where they can execute their command.

How to Find XSS Vulnerabilities

The best way to find XSS vulnerabilities is by using a tool like Burp Suite. Using a tool like this, you can simulate how someone would send an email message the website. This will help you find any vulnerabilities that are present in the website before they become exploited.
This is a very important lesson because it teaches you how to protect your website from malicious code injection and other vulnerabilities associated with XSS. It also teaches you how to avoid being hacked as well!

How do I know if my website is vulnerable to XSS?

If you have a website that accepts input, and that input can be changed by an attacker, then your website could be vulnerable to XSS.
XSS is a vulnerability in which malicious code is injected into otherwise innocuous web applications, causing a host of security issues. In order to exploit a XSS vulnerability, a hacker must send a message to a vulnerable application that accepts input. For example, if a site shows an online form with fields for username, password and email address and the user can input their username and password but not their email address. An attacker must find a way to send malicious code to the application so that it can accept the input, and cause the application to do something it wasn’t designed to do. The best way to exploit this vulnerability is by sending an email with malicious code within it. In this example, the hacker would send an email with malicious code that exploits the vulnerabilities of your website when it displays an online form with fields for username, password and email address.
