CVE-2012-0163

Status: ModifiedHigh (9.3)—💥 Exploit

Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 does not properly validate function parameters, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka ".NET Framework Parameter Validation Vulnerability."

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
