CVE-2022-45066 Auth

This issue can be exploited by attackers to access and modify data by injecting malicious code through the backend. Users with broken access control rules in place on the site, allowing them to see any of the gallery’s content, are at risk. This is a cross-site scripting vulnerability that can be exploited by attackers to inject malicious code into the site’s backend through the use of client-side scripting. In order for a hacker to exploit this issue, they must be able to insert malicious code into the hosting server’s HTML code. If you are running a firewall or access control system, then you must allow access to the server’s HTML code on port 80. If you are not running any access control system and the server’s HTML code is blocked, then you must reconfigure your firewall or access control rules to allow access to the server’s HTML code on port 80.


The following symptoms would indicate that an attacker is exploiting this vulnerability:
- Site is inaccessible or not responding
- HTML code in the browser is different than the site’s design or content
- Jquery scripts are running on the client side in a different order, leading to unexpected behaviour
- Users with broken access control rules can see any content within the gallery

Solution: Disable User-Friendly Layouts on Site

The site was vulnerable to cross-site scripting due to the fact that it used user-friendly layouts. This means that there is an increased possibility of those with malicious intentions being able to exploit the site and inject malicious code through its backend. The solution for this issue is to disable all user-friendly layouts; otherwise attackers will be able to exploit the vulnerable code.

What is the Cross Site Scripting?

Cross-site scripting (XSS) vulnerabilities occur when a web application is using client-side scripts to generate output, and the input that it receives from users comes from malicious sources. The client-side script can be written in a way that allows attackers to inject malicious code into the HTML of the website, which can then be executed on visitors’ machines.
This type of vulnerability is one of the most dangerous because attackers are able to execute their malicious code without any user interaction. This means that if an attacker can exploit such a vulnerability and gain access to a site’s backend, then they could use this capability to take over and modify anything on it.
