.oO Overview Oo.
CoolForum v 0.5 beta shows PHP content files
Discovered on 2002, September, 16th
CoolForum v 0.5 is a PHP forum. This forum can show content of PHP files.
.oO Details Oo.
This forum contains a file named "avatar.php". This file can show an image
stored in the "logos" directory. Here is the source file of avatar.php :
<? header('Pragma: no-cache');
else if (ereg(".gif",$img))
What this file do ? It's simple : It takes the name of the file as argument,
read it fully, and send back the content to your browser.
The security flaw is that *any* file, in or *out* the logos directory can be
show, bypassing *any* protected directories...
.oO Exploit Oo.
.oO Solution Oo.
The exploit is really easy. The aim is to read the "connect.php" file in the
"secret" directory. "connect.php" contains the informations about the
database connection and "secret" directory is protected by a .htaccess file.
You can do the exploit with any browser by using this syntax :
Of course, replace <Forum_URL> by the vulnerable server.
You will get a blank page. If you edit the source of this web page, you'll
get the jackpot...
The vendor has been informed and has solved the problem.
