Telerik Revisited

Markus Wulftange · Code White

Re-examines CVE-2017-11317 in Telerik UI for ASP.NET and finds it is more than an arbitrary file upload: the rauPostData blob carries an assembly-qualified type name handed to JavaScriptSerializer, giving arbitrary deserialization. Using AssemblyInstaller to load a mixed-mode DLL runs its DllMain, so unauthenticated code execution needs no write access to the web root.
