CVE-2008-4552
HighSummary
Funkcja good_client w nfs-utils w wersji 1.0.9 oraz prawdopodobnie innych wersjach przed 1.1.3 wywołuje funkcję hosts_ctl w niewłaściwej kolejności argumentów. To powoduje, że TCP Wrappers ignoruje netgroupy, co pozwala zdalnym atakującym na obejście zamierzonych ograniczeń dostępu.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do zasobów, co może prowadzić do wycieku danych lub innych poważnych incydentów bezpieczeństwa.
Recommendation
Zaleca się aktualizację nfs-utils do wersji 1.1.3 lub nowszej, aby usunąć tę podatność oraz wprowadzenie dodatkowych środków zabezpieczających w celu ochrony przed nieautoryzowanym dostępem.

Original NVD description (English source)
The good_client function in nfs-utils 1.0.9, and possibly other versions before 1.1.3, invokes the hosts_ctl function with the wrong order of arguments, which causes TCP Wrappers to ignore netgroups and allows remote attackers to bypass intended access restrictions.
