Vulnerability from certfr_avis

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).

Summary

Asterisk Open Source 1.2.x before 1.2.26 and 1.4.x before 1.4.16, and Business Edition B.x.x before B.2.3.6 and C.x.x before C.1.0-beta8, when using database-based registrations ("realtime") and host-based authentication, does not check the IP address when the username is correct and there is no password, which allows remote attackers to bypass authentication using a valid username.
