Microsoft has released CVE-2018-8202 (KB4338417, KB4340558 and KB4340559) for a vulnerablility in .Net.
The down effect is I got many “ActiveX component can’t create object” errors. See https://stackoverflow.com/questions/51289285/how-do-i-properly-instantiate-32-bit-com-objects-in-classic-asp-after-installing for more people having this problem and some solutions.
The only fix for our users is to go to IIS > Website > Authentication > Anonymous Authentication > Set to ‘Application Pool Identity’.
Is there any reasens why SolidCP force IIS to use specific authentication insteed of AppPool?
And can i configure SolidCP so all (new) sites are created with AppPool Identity?
