Security :: Getting Error System.Security.SecurityException?
Apr 5, 2010
I'm getting the error
"System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
When trying to access my simply aspx form on our local network. It works fine when debugging using Microsoft Visual studio 2008 however, when I deploy the aspx form on IIS 7.0 I get the error above. The form was working fine until I added a ajax calendar extender. I've also reviewed other posts relating to this one, such as changing<trust level="Full"> with no avail. I have listed a portion of my web.config file below.
<system.web>
<trust level="Full" originUrl=""/>
<compilation debug="false">
<assemblies>
<add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

I am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

I have an ASP.NET application that was working fine on my server up until last night when I installed a bunch of windows updates, now it's throwing this exception : System.Security.SecurityException: Requested registry access is not allowed.Unfortunately there is some things that makes this hard to debug. I added the debug="true" attribute to the web.config file to get the line where the exception is lauched. The line identified in my code is an End If and the code just before seems benign :
<body id="body" runat="server">
<div class="conteneur-confirmation">

Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, ersion=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
it is this bit of code that is causing this
[Code]....
If i comment this out, the PDF builds and no errors are thrown (there is just no image)
I don't understand cause I am am trying to do is read a file.

Here is my code
[Code]....
"fileUpload" is the FileUpload ASP.NET control. The SaveAs method writes the user uploaded file to a specified location on the server. IT WORKS. That tells me that the ASP.NET process has the proper write permission to write to the file.The next line uses an assembly called PdfSharp which you can use to open PDF files and manipulate them. In this case, the line simply opens up the user uploaded file. That is where the error occurs. WTH?
It works on my production machine. It does not work on my local machine. It USED TO. It was never a problem before.So why would it be fine to WRITE to the server, but trying to open a file give an error? Makes no sense. Googling yields a suggestion to put <trust level="Full" originUrl="" /> under <system.web> in web.config. It does not work.

I have a web site that is using windows authentication. 'Enable anonymous access' is unchecked. It works when I call it through Visual Studio but when I put the site on the server I get the following error:
Unable to cast object of type 'System.Security.Principal.GenericPrincipal' to type 'System.Web.Security.RolePrincipal'.
Here is the offending line:
System.Security.Principal.GenericPrincipal genericPrincipal = (System.Security.Principal.GenericPrincipal)HttpContext.Current.User;

I've researched the System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. error.
So far all the suggestions indicate either a custom assembly that needs a permission change (I don't have any custom assemblies) or requires a setting change on the server (I'm not the admin). This is for a ReportViewer app using RDLC files. So my questions are: Are there any other things to try troubleshooting?
I'm a complete newb at attempting to understand (I don't) what I've read on this subject regarding the server admin part. What do I need to tell the server admin to check out and/or change? I've looked at the commonly referenced post on wss_mediumtrust.config (I have no idea what that is). Post link. But with no clue on what the post is talking about I don't know what to ask the admin for.

There seems to be an issue with the "Trust" level when executing within a "Cloud" environment. In order for the following app to work it needs a trust level of at least "Medium." This web app is developed using VB.NET 3.5, and Visual Studio 2008. The app works perfectly on my local sever but when deployed/published to the "Cloud" it returns the error: System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I have added all 4 required values, ConsumerKey, ConsumerSecret, OAuthToken, and OAuthTokenSecret to the web.config file in the "appSettings" section of the "configuration"
[Code]....
If found that by going to [URL] and signing into the account that is using the application, then go to the "Settings" page, go to the bottom of the page and click on the "API" menu option. Once the API page appears you will clik on the button "2", Register An App. On the right side on the new page, you will see a button "View Your Applications." If you have previously registered your app, click this button, If not fill out the appliction for a new app. Now at the View your Applications page, select the app you want to get the authorization keys for where is says "Edit Details". Now click on the button to the right that says, "Application Detail." Here you will find your Consumer Key and your Consumer Secret Key. On the right side of this page you will see the menu option "My Access Token", click it and you will find your oauth_token and your oauth_token_secret keys! Not that you have all the keys, put them in the "appSettings" section of the web.config file. Add "Dim twConn As New TwitterVB2.TwitterAPI" at the top of the page.
I then created a subroutine where I pass in the Tweet:
[Code]....
This code works great in an enviornment that allows at least a "Medium" trust level. However it appears that many of the "new" hosting envrionments such as "Cloud Hosting" and others do not allow this trust level automatically!However if the trust level is less than "Medium" on your host you will likely receive the error message: "Twitter Returned: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed." If anyone has found a fix for this "Trust Level"

I am recently trying to set enough permissions to let web application write entries in System's "Event Log" .The following are the lines of code i added in web.config files:
<securityPolicy >
<trustLevel name="Full" policyFile="internal" />
<trustLevel name="CustomMedium" policyFile="customWeb_mediumtrust.config"/>
</securityPolicy >
<trust level="CustomMedium" originUrl=""/>
And here goes the html markups inside of customWeb_mediumtrust.config:
<configuration>
<mscorlib>
<security>
<policy>
<PolicyLevel Version="1">
<SecurityClasses>
<SecurityClass name="EventLogPermission"
Description="System.Diagnostics.EventLogPermission,System,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089"/>
</SecurityClasses>
<PermissionSet version="1" Name="ASP.NET">
<IPermission Version="1">
<Machine name="." access="Write"/>
</IPermission>
</PermissionSet>
</PolicyLevel>>
</policy>
</security>
</mscorlib>
<appSettings></appSettings>
<connectionStrings/>
</configuration>
The problem at the moment is that web.config generates the error "invalid syntax" if i include the line: <trust level="CustomMedium" originUrl=""/>. In case i remove the line , site compiles successfully. Did i go wrong any where with the above codes.

I have developed a ASP.NET C# web page which connects to remote conmputer command prompt using PSEXEC.exe and executes some command where the output of the command will get copied to the page. It works fine in the VS 2005 IDE.
If the page is accessed via IIS from IE, the task PSEXEC.EXE appears in task manager of the server with the system account privilege after the method is triggered but nothing happens.
find my present settings in IIS and others:
1. APP Pool Identity to Local System (Predefined) and also to a configurable admin account.
2. <processModel userName="SYSTEM" password="AutoGenerate" /> in Machine.Config file
Also I've tried impersonasation in web.config file to an admin account.

I'm a lowly DBA.I am supporting a web app that allows users to upload images (among other documents). The system is deployed and working and not having issues with the uploads. However, I upgraded my development box recently and since then I have been encountering an "access denied" issue. Initially I thought it was a simple security issue but now it seems it is more complex.

I've had a look through the forums but I couln't find a concrete answer - I found some things that point me in the right direction but I would like to just ask for some clarification.My requirements are as follows:I have an external system, with an API that allows me to log in a user, and returns whether or not it was successful. This can only be done through the API, it can not be done with a direct DB connection.I want to create a site that can only be accessed by someone who has a login to this external system. Through the site they will only be able to log-in, there will be no possibility to change password etc, this is all done in the external system by an admin.I like the ASP membership system, and the way it works with anonymous and member views and would like to continue to use it. My question is, how do I do this? Do I create a custom membership provider that overrides all the methods of the usual membership provider? And how will the fact that all I actually want to do is allow the user to login affect things? There will be no ability to change details etc.

I have a Win7 Pro laptop that I do my development on and it is in Domain1.I have a Win2003 server that has a shared folder on it and it is in Domain2. I have an impersonation routine in my code that allows IO to occur between my laptop and the server, it works.When I move the code to my Win2003 hosted servers the impersonation does not authenticate to the shared folder.Is there some kind of domain policy, IIS or Windows 2003 setting that prevents impersonation from occurring (there no impersonation in my web.config, only in code)? I saw in the security faq something about running the -ga command in order to grant the
permissions. What is this referring to exactly?

I need to convert a web site using traditional ASP.Net login,membership/role with SQL to a custom system. I need to use a third party (CAS) authentication system while still using membership and roles to control access to content and User.Identity functions.What would be the best way to accomplish this? I use the <deny> and <allow> user throughout the site to control page access.

I am the web developer at a medical clinic. I have 2 scenarios going on:
First, I have a physicians only component of our employee portal to allow access to only physician shareholders or physician non-shareholders. My structure is built like:
Physicians Only
Administration
Affiliations
Calendars
Compensation
Minutes
The Affiliations folder is only going to be accessible by the physician shareholders. Therefore, I have security roles set for Physicians Only and Affiliations. When I test, the security is set correctly on the folders. However, when I try to login as different people, all with different roles, I have to login with user name and password, twice, before the system allows me in.
Secondly, I have secured areas within the employee portal also. However, when I navigate to them, the system doens't usually prompts me to login. If it does prompt me to login, it too, is on the second try. So how does it know who I am? And more importantly, how do I get the system to actually prompt the user to login with their credentials?
