Vulnerability from certfr_avis - Published: 2012-02-03 - Updated: 2012-02-03

De multiples vulnérabilités dans Drupal permettent de contourner des restrictions d'accès à des fichiers, de modifier des informations d'utilisateur et d'injecter illégitimement des requêtes par rebond.

Description

De multiples vulnérabilités ont été découvertes dans Drupal :

  • OpenId ne vérifie pas si certains attributs sont signés, ce qui permet de modifier les informations des utilisateurs (CVE-2012-0825) ;
  • des injections de requêtes illégitimes par rebond sont possibles via le module Aggregator. Dans certains cas, l'exploitation de cette vulnérabilité permet de réaliser un déni de service (CVE-2012-0826) ;
  • sous certaines conditions, des utilisateurs peuvent télécharger indûment des fichiers via le module File. Ce problème n'affecte que les versions 7.x de Drupal (CVE-2012-0827).

Solution

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
