CERTA-2009-AVI-324

Vulnerability from certfr_avis

Une vulnérabilité dans ASP.NET permet à un utilisateur malveillant de réaliser un déni de service à distance.

Description

Le composant Microsoft .NET Framework de Microsoft Windows ne gère pas correctement les files de requêtes quand Internet Information Services 7.0 (IIS) est installé et que ASP.NET est configuré pour utiliser le mode « intégré » et non le mode « classique ». Un attaquant peut créer des requêtes HTTP anonymes spécialement conçues pour épuiser les ressources du serveur Web vulnérable.

Les versions Vista Starter et Familiale Basique ne sont pas concernées car elles ne supportent pas IIS 7.

Solution

Se référer au bulletin de sécurité MS09-036 de Microsoft pour l'obtention des correctifs (cf. section Documentation).

Plateformes :

Microsoft .NET Framework 2.0 SP1 et SP2 ;
Microsoft .NET Framework 3.5 et 3.5 SP1.

sur systèmes d'exploitation :

Windows Vista et Vista SP1, versions x64 comprises ;
Windows Server 2008 pour architectures 32 bits, x64 et Itanium.

Summary

ASP.NET in Microsoft .NET Framework 2.0 SP1 and SP2 and 3.5 Gold and SP1, when ASP 2.0 is used in integrated mode on IIS 7.0, does not properly manage request scheduling, which allows remote attackers to cause a denial of service (daemon outage) via a series of crafted HTTP requests, aka "Remote Unauthenticated Denial of Service in ASP.NET Vulnerability."
