CVE-2008-4254
HighSummary
W kontrolce ActiveX Hierarchical FlexGrid (mshflxgd.ocx) w Microsoft Visual Basic 6.0 oraz Visual FoxPro 8.0 SP1 i 9.0 SP1 i SP2 występują wielokrotne przepełnienia całkowite. Atakujący mogą zdalnie wykonać dowolny kod, manipulując właściwościami Rows i Cols w metodach ExpandAll i CollapseAll, co prowadzi do nieprawidłowego dostępu do zainicjowanych obiektów oraz uszkodzenia 'stanu systemu'.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, umożliwiając atakującym zdalne wykonanie kodu, co może prowadzić do przejęcia kontroli nad systemem. Może to skutkować utratą danych, naruszeniem poufności oraz destabilizacją systemów.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszych wersji, które eliminują tę podatność. Dodatkowo, warto ograniczyć użycie kontrolki ActiveX w aplikacjach oraz monitorować systemy pod kątem nieautoryzowanych działań.

Original NVD description (English source)
Multiple integer overflows in the Hierarchical FlexGrid ActiveX control (mshflxgd.ocx) in Microsoft Visual Basic 6.0 and Visual FoxPro 8.0 SP1 and 9.0 SP1 and SP2 allow remote attackers to execute arbitrary code via crafted (1) Rows and (2) Cols properties to the (a) ExpandAll and (b) CollapseAll methods, related to access of incorrectly initialized objects and corruption of the "system state," aka "Hierarchical FlexGrid Control Memory Corruption Vulnerability."
