Vulnerability from certfr_avis - Published: 2007-12-24 - Updated: 2007-12-24

Une vulnérabilité dans Asterisk permet de contourner le mécanisme d'authentification.

Description

Une vulnérabilité a été découverte dans Asterisk. Lorsque l'enregistrement des utilisateurs s'appuie sur la base de données et que l'authentification se base sur les machines, Asterisk ne vérifie pas l'adresse IP source si le nom d'utilisateur est valide et s'il n'a pas de mot de passe. L'exploitation de cette vulnérabilité permet de contourner le mécanisme d'authentification.

Solution

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