CVE-2011-1978

Estado: ModificadaMedia (4.3)—

Microsoft .NET Framework 2.0 SP2, 3.5.1, and 4 does not properly validate the System.Net.Sockets trust level, which allows remote attackers to obtain sensitive information or trigger arbitrary outbound network traffic via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka "Socket Restriction Bypass Vulnerability."

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
