CERTA-2009-AVI-324
Vulnerability from certfr_avis - Published: 2009-08-12 - Updated: 2009-08-12
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.
- Windows Vista et Vista SP1, versions x64 comprises ;
- Windows Server 2008 pour architectures 32 bits, x64 et Itanium.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
