RCE by uploading a web.config
Where an IIS upload filter blocks executable extensions such as .asp and .aspx, uploading a web.config instead is allowed. That file registers an ISAPI handler for .config and removes the request-filtering entries that hide it, so the uploaded config executes the ASP embedded in its own comments, yielding remote code execution as nt authority system.
