I have an ASP.NET Application running on IIS windows 2008R2 Server, everything is working ok however users are able to access the direct files in subfolders. What i am looking for is a way to prevent the users from accessing anything outside of the default document.
I have tried removing the security to the sub folders and files but this leads to an issue that the application cannot gain access to the files in sub folders.
The application pool is running under application pool identity and the folders have the permission only for the application pool identity.
I have also tried many other variations but i cannot seem to remove the access to these files without causing the application not to work.

I have an AspNet App (Blazor) running on IIS server.
I would like to create a txt file on the server, but it doesn't work.
I changed the AppPool identity to a domain user accound and the directories in E: have full permissions for this account.
It works in VisualStudio IIS Express, but not in IIS.
Anyone here who can help me? A permission problem`?
C# Code for creating txt file:
File.WriteAllText(#"E:\Publish\Export\Test.txt", "Hello World");
If you want to save to a specific path, use MapPath (or Server.MapPath) to get the physical path corresponding to the application. Because by default the web server (IIS or local development server) will save to its working directory.
Also you need to make sure the account running IIS has read/write permissions to the directory you need to write to. If you're looking for user accounts, go to "Advanced Settings" under Application Pools and check what's set for "Identity".
I'm working on the Umbraco site (asp.net MVC) hosted on local Windows Server 2016+IIS10.
During regular template modification, I have experienced strange behavior - the site lost all of the assets hosted from local files. All the requests to cases or images were redirected to the login page. A few people reported similar behavior, commonly resolving it by permission checking. So did I - ensured that my pool user has granted full access to the folder and all its descendants. It was, so I removed it and applied it once again. Still no luck. I have copied the website files and created another web app in IIS - this one worked without any glitch.
Later, my co-worker found that the application folder is missing access permission for the local machine "Users" group. When we added it - the site is served without any issues.
The webserver is part of the corporate domain (AD) and the app pool user is a "service user".
Is it normal that it needs both - pool user and local "Users" permission?
Why is so?
It is normal. When the static file and the application are in same machine, the application needs higher permissions to read the static file.
When the application runs in IIS, it will use the identity of the application pool to read static files, and the default identity of the application pool is ApplicationPoolIdentity, with the lowest permissions.
The test in visual studio does not have this problem because IIS express runs the application with the same permissions as the administrator.
I removed applications from IIS. But still the app pool showing the same apps. Due to this i am not able to delete the app pool.
Is there any other way to delete app pool from IIS?
Thanks,
Prasad
If you removed the applications by deleting their folders, simply add the folders back to the drive with the same paths and names. They can be empty. Then refresh IIS and the applications should show there again. Delete the applications in IIS, then you can delete the folders again. Refresh IIS and they should be gone.
So, I've been trying to give my web application read access to files in root/documents folder that I have created. I don't want the public to have access to this folder. Have managed to lock out public users through the documents folder authentication setting by disabling the anonymous authentication setting.
Having much larger problems giving the web app read access to files in that folder. Have added the apppool into the read folder permisions of the documents folder but still getting access denied messages.
Just wondering if there's anything else that may be affecting the applications access to the directory.
Try adding NETWORKSERVICE as a reader to the folder.
On the other hand, you can try using impersonation and give read access to impoersonated user.
Setting the .Net trust level to Medium on a site will ensure that no code can access files outside the application directory.
I have an ASP.Net site that must run in Full Trust. I have configured my website in IIS to use its own Application Pool Identity (IIS Apppool\www.site-name.com).
Currently it is possible for scripts/code in this app to read files outside of the application directory. This occurs because by default, accounts that are a member of the BUILTIN\users group are able to read most files on the system, including c:\ and c:\windows. It appears that Applicaion Pool Identity accounts are also members of BUILTIN\users.
Is it possible to prevent file access outside the website folder while keeping Full Trust?
How about using file/directory ACL to deny your AppPoolIdentity access to needed folders?
