ace of hearts

Port 20011

We had a image gallery here with 4 user galleries.

Sarah’s gallery John’s gallery Ripley’s gallery Ash’s gallery

John’s gallery was not accessible, set to private.

When querying any other gallery, we could see the URL changing like so:

http://172.17.15.117:20011/gallery?galleryUrl=/admin

I tried to call the admin gallery through local-host and got access to the admin panel, where I just had to untick a box for making John’s gallery public.

http://172.17.15.117:20011/gallery?galleryUrl=http://127.0.0.1:20011/admin

He had this flag inside:

Yay an Ace!!! — Starry-Lord
