spoofing

About this tag
Spoofing vulnerabilities in Microsoft products are a recurring theme on WindowsForum.com, with discussions covering CVE entries for .NET, Office, Azure Cosmos DB, SharePoint Server, Exchange Server, Dynamics 365 Field Service, and Microsoft Teams. These flaws typically involve presentation-layer issues, UI misrepresentation, or improper input validation that allow attackers to impersonate legitimate interfaces or users. Threads emphasize the urgency of applying vendor patches, verifying CVE-to-KB mappings, and implementing layered mitigations. Common advice includes treating vendor advisories as canonical, using interactive MSRC pages for accurate mapping, and assuming realistic risk models for social-engineering-assisted attacks. The tag covers both on-premises and cloud services, with severity ratings ranging from medium to high.
