CVE-2008-3464
HighSummary
Podatność w afd.sys w komponencie Ancillary Function Driver (AFD) w systemach Microsoft Windows XP SP2, SP3 oraz Windows Server 2003 SP1 i SP2 polega na niewłaściwej walidacji danych wejściowych przesyłanych z trybu użytkownika do jądra. Umożliwia to lokalnym użytkownikom uzyskanie podwyższonych uprawnień za pomocą odpowiednio skonstruowanej aplikacji.
Risk Assessment
Ryzyko dla organizacji polega na możliwości uzyskania przez lokalnych użytkowników nieautoryzowanego dostępu do systemu z podwyższonymi uprawnieniami, co może prowadzić do poważnych naruszeń bezpieczeństwa.
Recommendation
Zaleca się aktualizację systemów operacyjnych do najnowszych wersji oraz wdrożenie odpowiednich zabezpieczeń, aby zminimalizować ryzyko wykorzystania tej podatności.

Original NVD description (English source)
afd.sys in the Ancillary Function Driver (AFD) component in Microsoft Windows XP SP2 and SP3 and Windows Server 2003 SP1 and SP2 does not properly validate input sent from user mode to the kernel, which allows local users to gain privileges via a crafted application, as demonstrated using crafted pointers and lengths that bypass intended ProbeForRead and ProbeForWrite restrictions, aka "AFD Kernel Overwrite Vulnerability."
