Question 1

What is XSS and why is it dangerous?

Accepted Answer

What is XSS and why is it dangerous?

Cross-Site Scripting (XSS) is a type of security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. These scripts can steal information like passwords and cookies, deface websites, or redirect users to malicious sites. XSS exploits the trust a user has for a particular site, making it particularly dangerous as it can lead to unauthorized access and data breaches.

Question 2

How did the vulnerability in Exclusive Addons for Elementor occur?

Accepted Answer

How did the vulnerability in Exclusive Addons for Elementor occur?

The vulnerability in the Exclusive Addons for Elementor plugin was due to insufficient input sanitization and output escaping within the plugin’s InfoBox feature. This oversight allowed authenticated users with contributor-level access to inject arbitrary JavaScript code via the 'animating mask style' parameter. Such vulnerabilities highlight the importance of rigorous input validation in software development to prevent malicious data from being processed.

Question 3

What does 'authenticated (Contributor+) Stored Cross-Site Scripting' mean?

Accepted Answer

What does 'authenticated (Contributor+) Stored Cross-Site Scripting' mean?

Authenticated Stored Cross-Site Scripting (XSS) means that the XSS attack can be performed by users who are logged into the site, starting from the contributor level upwards. Stored XSS implies that the injected script is saved on the server, such as in a database, and is then presented to users who access the affected page. This type of XSS is particularly harmful as it can persist and affect multiple users over time.
