About this tag
The mitm tag on WindowsForum.com covers man-in-the-middle (MITM) attack scenarios, primarily focusing on Windows security vulnerabilities and certificate validation flaws. Discussions include CVE-2025-55229, a Windows certificate spoofing vulnerability that enables MITM attacks over a network, and CVE-2025-1001 affecting RadiAnt DICOM Viewer, which could be exploited for machine-in-the-middle attacks. Older content addresses HTTPS interception weakening TLS security, WPAD name collision risks, and Microsoft security updates for .NET Framework and Schannel that mitigate MITM spoofing. The tag is relevant for IT administrators and security professionals managing Windows environments, with emphasis on certificate handling, TLS configuration, and applying security patches to prevent MITM attacks.
