Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4, 4.5, and 4.5.1 does not properly determine whether it is safe to execute a method, which allows remote attackers to execute arbitrary code via (1) a crafted web site or (2) a crafted .NET Framework application that exposes a COM server endpoint, aka "Type Traversal Vulnerability."

Security readout for executives and security teams

CVE-2014-0257 is a Microsoft .NET Framework flaw that could let a remote attacker run code through a crafted website or a crafted .NET application exposing a COM server endpoint. The affected versions are old, but legacy Windows systems may still carry business risk. Exposure is most likely on legacy Windows hosts running the listed .NET Framework versions, especially browser-facing workflows or applications exposing COM server endpoints through .NET. Treat as high priority for legacy system remediation. The main business concern is remote code execution on outdated Windows/.NET assets, not a confirmed current exploitation campaign from the supplied evidence. Mitigation focus: Apply Microsoft MS14-009 security updates for affected .NET Framework versions.; Retire or isolate systems requiring unsupported .NET Framework versions.; Review vendor guidance before relying on compensating controls..
