DOM XSS in AngularJS expression with angle brackets and double quotes HTML-encoded

Introduction to DOM XSS in AngularJS expression with angle brackets and double quotes HTML-encoded.

DOM-based Cross-Site Scripting (XSS) is a web security vulnerability in DOM XSS in AngularJS, where untrusted data can be inserted into the DOM. To mitigate this, it is essential to use HTML-encoding to replace special characters with their corresponding HTML entities. Proper web security practices include validating and sanitizing user input, and applying output encoding to user-generated content. By prioritizing web security, adhering to best practices, and employing techniques like input validation, output encoding, and HTML entity encoding, developers can effectively protect against DOM XSS and maintain the security of their AngularJS applications.

Lab Solutions | Practical Work Time DOM XSS in AngularJS

This lab contains a DOM-based cross-site scripting vulnerability in a AngularJS expression within the search functionality.

AngularJS is a popular JavaScript library, which scans the contents of HTML nodes containing the ng-app attribute (also known as an AngularJS directive). When a directive is added to the HTML code, you can execute JavaScript expressions within double curly braces. This technique is useful when angle brackets are being encoded.

To solve this lab, perform a cross-site scripting attack that executes an AngularJS expression and calls the alert function.

Stepwise Solution of the lab DOM XSS in AngularJS

After accessing the lab, You can see there are lots of blogs. Right? Take a look. But actually, in this lab, the scenario won’t be the same as the previous one if you’ve been following our series you will understand what is the thing I’m talking about. 🙂

Let’s search random words to see how is ‘search’ functionality works or is applicable for DOM XSS (Cross-Site scripting)

Well, according to the lab description here we have to execute a payload of AngularJS expression alert function.


Let’s execute it and see what going to happen.

So, we successfully solved the lab.
