machinekey

About this tag
The machinekey tag covers discussions about ASP.NET machine keys, which are cryptographic material used by ASP.NET applications for view state validation, session security, and other purposes. Content highlights threats where attackers steal or exploit exposed machine keys to forge authentication tokens, execute code injection attacks, or achieve remote code execution (RCE) on IIS web servers and SharePoint deployments. Specific vulnerabilities discussed include CVE-2025-4427, CVE-2025-4428, and deserialization chains targeting SharePoint on-premises. The tag also covers patch guidance, indicators of compromise (IOCs), and security best practices for protecting machine keys in enterprise environments running Windows Server and IIS.
