Vulnerability from certfr_avis

Plusieurs vulnérabilités dans Microsoft Forefront Unified Access Gateway permettent à une personne distante malintentionnée d'exécuter du code arbitraire, de provoquer un déni de service ou d'effectuer des injections de code indirectes.

Description

Cinq vulnérabilités ont été découvertes dans Microsoft Forefront Unified Access Gateway :

  • trois vulnérabilités permettent d'effectuer des injections de code indirectes (XSS) (CVE-2011-1895, CVE-2011-1896 et CVE-2011-1897) ;
  • une vulnérabilité dans une appliquette Java utilisée par Microsoft Forefront Unified Gateway Access permet à une personne distante malintentionnée d'exécuter du code arbitraire (CVE-2011-1969) ;
  • une vulnérabilité dans la gestion des fichiers de session (cookie) permet de provoquer un déni de service IIS (CVE-2011-2012).
