# What is the App_Data Folder useful? #
# App_Data contains application data files including .mdf database files, XML files, and other data store files. #
# The App_Data folder is used by ASP.NET to store an application's local database, such as the database for maintaining membership and role information. #
# The App_Data folder is not public like the other website directories under the Home Directory. #
# Because it's a private directory, the IIS server hides it for security reasons. #
# Now, we will test whether such a directory exists. #
# If the directory exists, we will make it public so that we can define the necessary server functions for running a shell within it. #
# For this we will try to load a special server configuration file. This is a Web.Config file. With this we'll ByPass the directory privacy. #
# So the directory will be public and it will be able to respond to external queries and run a shell. #

" So what can we do if no directory on the site has write permission? "
" If not, we will test for vulnerabilities in the paths of other applications running on the server. "
" Sometimes this can be a mail service related vulnerability, "
" Sometimes also it can be a "Service Permissions" vulnerability. "
" Sometimes also it can be a "Binary Permissions " vulnerability. "
" Sometimes also it can be a "Weak Service Permissions" vulnerability. "
" Sometimes also it can be a "Unquoted Service Path" vulnerability. "
" Our limits are as much as our imagination... "
" *** 0DAY *** "
" Ok. Now we will strengthen our lesson by exemplifying a vulnerability in the SmarterMail service. "
" We saw that the SmarterMail service was installed on our IIS server and we detected a critical security vulnerability in this service. "
" TEST WORK for SmarterMail Service: [ http://mail.pentest.com/interface/root#/login ] "
" Data directory for this SmarterMail: [ C:\Program Files (x86)\SmarterTools\SmarterMail\MRS\App_Data ] "
" As shown above, we can first navigate to the App_Data directory belonging to the SmarterMail service, "
" And then upload our shell file to the server by bypassing it. "
" This way, we will have full control over both the server and the mail service. "
" Shell Path: [ http://mail.pentest.com/App_Data/shell.aspx ] "
