CVE-2008-4110
HighSummary
Przepełnienie bufora w kontrolce ActiveX SQLVDIRLib.SQLVDirControl w pliku sqlvdir.dll w Microsoft SQL Server 2000 umożliwia zdalnym atakującym spowodowanie awarii przeglądarki lub potencjalne wykonanie dowolnego kodu poprzez długi URL w drugim argumencie metody Connect.
Risk Assessment
Ryzyko dla organizacji polega na możliwości zdalnego wywołania awarii usługi lub wykonania nieautoryzowanego kodu, co może prowadzić do utraty dostępności lub bezpieczeństwa systemu. Jednak w wielu środowiskach problem ten nie stanowi zagrożenia, ponieważ kontrolka nie jest oznaczona jako bezpieczna do skryptowania.
Recommendation
Zaleca się monitorowanie i aktualizację środowiska SQL Server 2000 oraz rozważenie ograniczenia dostępu do kontrolki ActiveX w przeglądarkach. Warto również rozważyć zastosowanie nowszych wersji SQL Server, które nie mają tej podatności.

Original NVD description (English source)
Buffer overflow in the SQLVDIRLib.SQLVDirControl ActiveX control in Tools\Binn\sqlvdir.dll in Microsoft SQL Server 2000 (aka SQL Server 8.0) allows remote attackers to cause a denial of service (browser crash) or possibly execute arbitrary code via a long URL in the second argument to the Connect method. NOTE: this issue is not a vulnerability in many environments, since the control is not marked as safe for scripting and would not execute with default Internet Explorer settings.
