Hi,
Code:

<?php
//instruction de comptabilisation de telechargement
//Utilisation
$fichier = "telechargement/".$_GET['fichier'];
$nom_fichier = $_GET['fichier'];

// téléchargement du fichier
header('Content-disposition: attachment; filename='.$nom_fichier);
header('Content-Type: application/force-download');
header('Content-Transfer-Encoding: fichier');
header('Content-Length: '.filesize($fichier));
//header('Pragma: no-cache');
//header('Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0');
header('Expires: 0');
readfile($fichier);
?>

I could download everything I want including php pages, but can I do somthing more interessant? example, in the first header line? $nom_fichier can it be replaced by any injection, my ultime aim is to hack this website Wink

What you have here is called Remote File Disclosure.
You can reveal the contents of all files on target server

1. IF current UID/GID and file/dir permissions will let you read the file
2. IF target file resides on same logical disk
3. IF php safe_mode/open_basedir does not interfere

So your mission is to escalate your privileges.
By the way - what is your ultimate goal? To mess with
specific website on hosting server or you want server itself?
In first case you can try to find configuration files containing
possible usernames and password hashes for database and/or
web applications. This may give you a way to get administrator rights
for web app and next goal can be php shell.
One more thing - scan target server for open TCP ports and look for
port 3306 (mysql). This may be handy later ...
And - as you can reveal source code of php scripts, then search
for more useful security vulnerabilities - Remote Command Execution, etc.

Badrh0 salam.

I see that you're trying again.
Perhaps you have to think more than more before to continue.
See you later.

badro4u salam

you wrote this :

"Assalamou 3alaykoum
Merci beacoup monsieur le directeur, ça me fait plaisir, dans d'autres forums on m'aurait envoyé balader si j'avais fais cette demande, thanx.
J'ai une question tout de même, cela prendra-t-il longtemps avant que ce site n'apparaisse sous Google quand je fait la recherche "badrh0" ??? ou alors pouvez vous faire quelquechose contre ça Monsieur le directeur ? Merci"

Apparemment tu laisses beaucoup de traces "higgs_b0s0n"

"http://www.ibndz.com"

Essayes d'être un peu intelligent et trouve un autre moyen.

Nassiha lillah.

Bof ! Tu crois que c'est le scoop du siecle de découvrire que badrh0 = higgs_b0s0n = badro4u ??!!! une simple recherche sur Google te donne ça! et laisse moi te dire quelquechose, j'avais même fait une bétise en laissant trainer mon vrai nom sur le net (avant que je commence a hacker) si tu es si fort que ça donne le moi :p et personne ne s'est donné la peine de le vérifier...
Quant au site ibndz c'était une bétise de débutant de ma part Smile et j'ai tant bien que mal éssayer de la réparer, mais t'inquittes je sais beaucoup plus de choses à présent Wink ...
Amicalement

Salam alikoum.

Le problème, c'est ce que peuvent savoir les autres sur toi et non pas moi.
Moi avec modestie je répond que je te connais pas Wink
La modestie est une KHISSLA rare chez les gens.
Sinon ton nom et le reste, je ne veux pas te le donner car sur le Net et tu sais pourquoi. Ou alors je vais te le communiquer d'une manière où tu dois faire bouger un peu tes neuronnes sous forme d'un Hash et c'est à toi de jouer.
Le savoir et les astuces sont devenus la propriété de tout le monde comme ils disent EL AWLAMA. Ne sommes pas dans un village où tout le monde connait tout le monde. Il reste l'art de se faire tout petit tout en étant grand.

Salam

Waraxe, plexi Shai-tan Twisted Evil autant de pseudo qui disent long sur le comportement.

Shai-tan est fier de l'être et il le sait surtout quand je lui ai expliqué ce que veut dire son pseudo.

D'ailleurs on sait qu'il y'a des gens qui peuvent se rallier avec ShaiTan pour arriver à leurs fins. Chez d'autres gens ça s'appelle LA TAKIYA.
