Chocolate Chips with Zero-G

Description

Hello W-Team,

Recon has found an old website from OmniFlags. We think there may be an insecure admin portal somewhere. See if there is anything you can find! They never did hire the best developers.

Report back, HQ

Milky Way

We are brought to the moon on this website, with both a navigation bar and a sidebar, though some of the options, such as "CAREERS" and "FLAGS", link to nothing

From the description we know we're looking for an "insecure admin portal", so let's see what we can find. Inspecting the page shows that we are currently on index.html. Let's try searching for the admin page with admin.html

-> This is done by adding the /admin.html path to the URL

We found the login portal

Let's try logging in with any test credential, say "admin" and "admin"

No luck

Inspect element again, and in the Sources tab we can find a script.js. Looking through it, it seems to hold the logic for login. Notably, we find this bit for when the credentials are submitted:

Admin

Looks like it sets the cookie admin to false when we login. If we have submitted our credentials and the admin cookie is false, it redirects us to denied.html

We can go into Application > Storage > Cookies to find the admin cookie, set it to true, then refresh the page to get the flag

Flag
