If we click on the Buy button, a cookie get's generated containing the basket list. (like JWT)
We can decode the cookie at the following website.
There isn't any kind of algorithm involved in generating the cookies. That means we can modify the cookie and can even make it malicious.
The website looks like a node application, so i will insert a node command to process. The cookie loads its content at /basket
We get Remote Code Execution, so let's try to list the files in the working directory.
require('fs').readdirSync('.').toString()
require('fs').readFileSync('flag.txt')
And we get the flag.
