Microsoft .NET Framework 2.0 SP2, 3.0 SP2, 3.5, 3.5.1, 4.5.2, 4.6, and 4.6.1 allows man-in-the-middle attackers to obtain sensitive cleartext information via vectors involving injection of cleartext data into the client-server data stream, aka "TLS/SSL Information Disclosure Vulnerability."

Security readout for executives and security teams

CVE-2016-0149 is a Microsoft .NET Framework TLS/SSL information disclosure issue. A network attacker positioned between a client and server could potentially cause sensitive information to be exposed in cleartext. The source bundle does not show active exploitation, but affected legacy .NET versions should be treated as patching debt. Exposure is most likely on Windows systems or applications using the listed .NET Framework versions for TLS/SSL-protected client-server communication. The provided affected-product metadata is incomplete, so inventory should rely on installed .NET versions and Microsoft MS16-065 guidance. Treat this as a moderate confidentiality risk and legacy platform hygiene issue. Prioritize systems handling sensitive data or using old .NET Framework versions, especially where network interception risk is credible. Mitigation focus: Review Microsoft MS16-065 for the relevant .NET Framework security updates.; Patch or retire systems running the listed legacy .NET Framework versions.; Prioritize internet-facing or sensitive client-server applications using .NET TLS/SSL..
