Vulnerability from certfr_avis

Une vulnérabilité dans la mise en œuvre de Kerberos sous Microsoft Windows permet à un utilisateur malintentionné d'élever ses privilèges.

Description

Une vulnérabilité est présente dans la mise en œuvre de Kerberos sous Microsoft Windows. Elle est due à la possibilité d'utiliser un algorithme de chiffrement obsolète lors de communications entre clients et serveur. La faiblesse du chiffrement peut alors permettre à un utilisateur malintentionné authentifié sur le domaine d'élever ses privilèges.
