While building out web applications, developers must follow best practices. And sanitizing user input is one of them. Processing unsanitized user input is responsible for many of the discovered vulnerabilities.
In this lab, the web application is vulnerable to a Reflected Cross-Site Scripting attack. A simulator is provided to simulate the attack and the source code of the application can be edited through the provided code editor.
Objective: Patch the source code of the web application to prevent Reflected Cross-Site Scripting.
The attack can be simulated by clicking on "Start Attack" button on the simulator
In the code editor, the code changes can be saved by using the save shortcut key: CTRL+"s"

If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.
Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email firstname.lastname@example.org clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
