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