CVE-2012-4777
HighSummary
Funkcja optymalizacji kodu w implementacji refleksji w Microsoft .NET Framework 4 i 4.5 nie egzekwuje poprawnie uprawnień obiektów, co pozwala zdalnym atakującym na wykonanie dowolnego kodu poprzez (1) spreparowaną aplikację XAML w przeglądarce (XBAP) lub (2) spreparowaną aplikację .NET Framework.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, umożliwiając atakującym zdalne wykonywanie kodu, co może prowadzić do utraty danych lub przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację do najnowszej wersji .NET Framework oraz wdrożenie odpowiednich zabezpieczeń, aby ograniczyć możliwość wykorzystania tej podatności.

Original NVD description (English source)
The code-optimization feature in the reflection implementation in Microsoft .NET Framework 4 and 4.5 does not properly enforce object permissions, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP) or (2) a crafted .NET Framework application, aka "WPF Reflection Optimization Vulnerability."
