Security Exception Over Reading/writing Files On Medium Trust?

Nov 21, 2010

I'm working on a project in ASP.Net, and it requires reading/writing to files on my server. I'm hosted at GoDaddy, and they swear they've got me at Medium Trust. When I try to read or write files that are in my own domain, I get Security Exceptions. I've tried multiple ways of opening/saving the files and they all return security errors. Here's the most recent error and offending line of code (I didn't save them all, they're all pretty much the same thing):

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed.

PngBitmapEncoder pbe = new PngBitmapEncoder();
pbe.Frames.Add(BitmapFrame.Create(new Uri("ornament.png", UriKind.Relative))); <-- Error

I've also gotten the error when trying to read/write using FileStream, Bitmap.Save and new Bitmap("ornament.png"). Could there be a problem with my Web.config? Is read/write supposed to be blocked by medium trust? This is a time-sensitive project and this is a brick wall for me. The deadline is end of business day tomorrow and GoDaddy isn't responding.

NInject Work In Medium Trust Hosting?

Apr 11, 2010

I'm doing shared hosting with GoDaddy and I developed a sample ASP.NET MVC app using Castle Windsor and unfortunately, it didn't work in a medium trust setting. Specifically, I got this error: "[SecurityException: That assembly does not allow partially trusted callers"... etc. GoDaddy is sadly not flexible in their trust policy.

I'm not tied to Windsor and would like to try another one that will work under Medium Trust. I'd actually like to use NInject, but I've read people having mixed success. The only one I've read that works with no problem is Microsoft's Unity.My question is, does NInject work in medium trust? If not, what are my options?

Security :: Compile Assembly In Medium Trust

I have an unsigned custom assembly, that has been deployed to the bin folder of my website. Trying to access a page that explicitly serializes a list using LOSFormatter produces the following exception:

I contacted my Hosting provider, and this was the reply:

This error is coming because your DLL Imbibe.DNN is developed in Full trust. We don't support full trust on shared server. You need to re-compile it again under medium trust. Now, what I am not aware of any option for compiling an assembly for medium trust. Can anybody here please desrible, how do I compile an assembly specifically for medium trust? I added the AllowPartiallyTrustedCallers attribute to the assembly manifest, but it did not resolve the problem.

Security :: CreateUserWizard In Medium Trust Environment?

Feb 22, 2010

We just moved our site (still in development) to a new hosting company, on a medium trust shared environment. We setup the databases, aspnet_users tables etc, but now our page that handles new people signing up doesn't work. It contains a simple standard <asp:CreateUserWizard> control. However, this page is not working since the move (the rest of our pages are working). We get this compiler error:

Request for ConfigurationPermission failed while attempting to access configuration section 'system.web/machineKey'. To allow all callers to access the data for this section, set section attribute 'requirePermission' equal 'false' in the configuration file where this section is declared.

Apparently the hosting company is using the default medium trust .NET settings. We have no idea how to get around this since we've always developed on full trust dedicated server environments. Is it simply a fact that the <asp:CreateUserWizard> control does not work in medium trust, or is there a way?

Security :: Change .Net App To TRUST=MEDIUM On Shared Server?

Mar 5, 2010

I've developed a dot net website that runs fine on my localhost. When I upload it to my ISP on a shared hosted site, I receive the following: "Required permissions cannot be acquired." I've been informed that I need to change my website to medium trust. Can someone get me started in the right direction on how this is done? When I add <trust level="Medium" originUrl="" /> to the web.config it won't BUILD on my local host and when I add it to the web.config on the shared site, it gives me"This configuration section cannot be used at this path. This happens when the site administrator has locked access to this section using <location allowOverride="false"> from an inherited configuration file."

Security :: IIS Error: Changing The Application's Trust Level In The Configuration File

May 15, 2010

Error Description while browsing the website under IIS "The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file." Initially I deleted the virtual directory, created again, set the permission to anonymous, set the browse and execute permissions, no solution. Then after doing many trials, I found out the basic problem reading the error "not allowed by the security policy". In web configuration file if we set the security policy to Fully Trusted, then problem solved and application working fine. or Set the trust level to the main configuration file in he "C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config"

C# - Can GhostScript Run In Medium Trust

Apr 23, 2010

I am using GhostScript to generate some thumbnails of PDF pages in an ASP.NET application. I have it wrapped in this library called GhostScriptSharp that just uses DllImport to call methods in the GhostScript DLL.It looks like this wont work on a medium trust hosting environment, either because of the fact that it is calling unmanaged code, or that it looks like the library is creating files all over the place (outside my virtual directory). I ran Process Monitor and saw it trying to Read, QueryNameInformationFile, CreateFile and QueryStandardInformationFile in places like:

C:WINDOWSsystem32HalftoneDefault
or
C:gsgs8.63libHalftoneDefault
or
C:gsfontHalftoneDefault

Any ideas about whether this is "fixable" to run in medium trust? If I can't use GhostScript, is there another free/open source library that WILL work in Medium trust?

MySQL Run Under Medium Trust?

Jan 22, 2010

I am trying to get a simple prototype using ASP.NET S#arp-architecture (Sharp architecture) to run on a shared hosting site. This site runs in medium trust, which appears to give problems with this framework. At first I went off on a wild goose chase with the mySQL.data.dll, but the latest version already supports partially trusted callers. The only way I found up until now is this blogpost, which basically describes re-compiling everything from the ground up, starting with the various Castle components. Is this the only way to get this to work, and more importantly, does this actually work?

I have had some good experiences with S#arp-architecture, and since I only have a few days to build this prototype, I figured S#arp-architecture would be a good match. So, my options are to stick with SA, or on the other end of the spectrum to hand-roll an MVC/NH/mySQL application.
