Vulnerability from certfr_avis - Published: 2011-12-13 - Updated: 2011-12-13

Deux vulnérabilités, permettant à un utilisateur malintentionné d'effectuer un déni de service à distance et de porter atteinte à la confidentialité de certaines données, sont présentes dans Asterisk.

Description

Deux vulnérabilités ont été découvertes dans Asterisk.

La première, AST-2011-013, permet à une personne malintentionée d'énumérer les noms d'utilisateur. Cette vulnérabilité est causée par une mauvaise configuration du NAT.

La seconde, AST-2011-014, permet à un utilisateur malintentionné de causer un déni de service à distance, lorsque l'option automon est activée dans le fichier features.conf, grâce à l'envoi d'une suite de paquets SIP.

Solution

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

AST-2011-013 concerne :

Asterisk Open Source 1.6.2.x toutes versions ;
Asterisk Open Source 1.8.x toutes versions.

AST-2011-014 concerne :

Asterisk Open Source toutes versions.

CVE-2011-4597 (GCVE-0-2011-4597)

Vulnerability from cvelistv5 – Published: 2011-12-15 02:00 – Updated: 2024-08-07 00:09

Summary

The SIP over UDP implementation in Asterisk Open Source 1.4.x before 1.4.43, 1.6.x before 1.6.2.21, and 1.8.x before 1.8.7.2 uses different port numbers for responses to invalid requests depending on whether a SIP username exists, which allows remote attackers to enumerate usernames via a series of requests.

Severity ?

No CVSS data available.
