Vulnerability from certfr_avis - Published: 2009-12-09 - Updated: 2009-12-09
De multiples vulnérabilités ont été découvertes dans le service d'authentification Internet de Microsoft. L'exploitation de ces vulnérabilités permet entre autres d'exécuter du code arbitraire à distance.
Description
Deux vulnérabilités ont été découvertes dans le service d'authentification Internet de Microsoft :
- la première résulte d'une mauvaise implémentation du protocole d'authentification PAEP et permet l'exécution de code arbitraire à distance ;
- la seconde résulte d'une mauvaise gestion des requêtes d'authentification MS-CHAP v2 et permet à un utilisateur mal intentionné d'avoir accès à des ressources d'un utilisateur privilégié.

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.
