  • Reuse security code between WCF and MVC.NET

    - by mrjoltcola
    First the background: I jumped into MVC.NET from the Java MVC world, so my implementation below is possibly cheating, I don't know. I avoided fooling with a custom membership provider and I just implemented the base code needed to authenticate and load roles in my LogOn action. Typically I just need to check roles programatically, and have no use for all of the other membership features, so I didn't originally think I needed a full Membership provider. I have a successful WCF project with a custom authentication and authorization layer that I did at least write per the proper API. I implemented it with custom IPrincipal, UserNamePasswordValidator and IAuthorizationPolicy classes to load from an Oracle database. In my WCF services, I use declarative security: [PrincipalPermission(SecurityAction.Demand, Role="ADMIN")]. The question (on the ASP.NET/MCV.NET side): All my reading indicates I should implement a custom Membership/Roles provider, and use [Authorize(Roles="ADMIN")] on my controller actions. At this point, I don't have a true Membership provider, but I'm using the same User class that implements the IPrincipal interface that works with the WCF security. I plan to share common code between the WCF and ASP.NET modules. So my LogOn action is not using the FormsService (and I assume this is bad). I had commented it out, and just used my "UserService" to access the Oracle db. Note my "TODO" comment below. public ActionResult LogOn(LogOnModel model, string returnUrl) { log.Info("Login attempt by " + model.UserName); if (ModelState.IsValid) { User user = userService.findByUserName(model.UserName); // Commented original MemberShipService code, this is probably bad // if (MembershipService.ValidateUser(model.UserName, model.Password)) if (user != null && user.Authenticate(model.Password) == true) { log.Info("Login success by " + model.UserName); FormsService.SignIn(model.UserName, model.RememberMe); // TODO: Override with Custom identity / roles? user.AddRoles(userService.listRolesByUser(user)); // pull in roles from db if (!String.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } else { log.Info("Login failure by " + model.UserName); ModelState.AddModelError("", "The user name or password provided is incorrect."); } } // If we got this far, something failed, redisplay form return View(model); } So can I make the above work? Can I stick the IPrincipal (User) into the CurrentContext or HttpContext? Can I integrate the custom IPrincipal I've already created without writing a full Membership/Roles Provider? I currently stick the User object into the session and access it from all MVC.NET controllers with "CurrentUser" property which grabs it from the session on demand. But this doesn't work with the [Authorize] attribute; I assume that is because it knows nothing about my custom Principal in the session, and is instead using whatever FormsService.SignIn() produces. I also found that session timeouts screw up the login redirect, the user doesn't get forwarded, instead we get a null exception accessing User from the session, and I assume it is related to my "skipping steps" to get a quick implementation. Thanks.

  • 2 iframes with the same display even if the src are different

    - by JulienH
    Hi, I am using this code: <div class="infobox-pair"> <div class="ibp-left"> <iframe width="105" height="350" frameborder="0" scrolling="no" style="width: 311px; height: 105px;" marginwidth="0" marginheight="0" name="infobox_flight" id="ibp-left-iframe" src="http://mywebpage.com/paris"></iframe> </div> <div class="ibp-right"> <iframe width="105" height="350" frameborder="0" scrolling="no" style="width: 311px; height: 105px;" marginwidth="0" marginheight="0" name="infobox_package" id="ibp-right-iframe" src="http://mywebpage.com/lisbonne"></iframe> </div> That is displaying into the same div two different iframes. When I display the page whatever the browser it happens that I can get the same content for both the iframes even if looking at the source code the iframe are still different (based on their src and id). It doesn't happen 100% of the time, I have to refresh sometimes several times to see it. Do you have any clue ? Thanks in advance

  • Facebook Connect - Security Warning

    - by Skoder
    Hey all, I'm using Facebook connect using FBML tags. Although it works, when I run the site in Internet Explorer, a security warning comes up similar to this: The current webpage is trying to open a site in your Trusted sites list. Do you want to allow this? Current site: http://www.facebook.com Trusted site: http://localhost" My Facebook code involves these two: http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php http://static.ak.connect.facebook.com/js/api_lib/v0.4/XdCommReceiver.js I tried changing them to HTTPS: https://ssl.connect... but the errors still appear. None of my pages use SSL. I've also tried turning facebook-logo='false' but still no luck. Any ideas on how to fix this? Although it's not show-stopping, it doesn't give a good impression to users who may be feel it insecure. Thanks

  • Flash CS4 AS3 Security Sandbox Violation

    - by Jennifer Heidelberg
    Hi, I have build my entire website with flash and embedded several swf objects (slideshows) into it. everything always worked fine when I published it as swf movie. but now that I want to upload my website an error message occurs saying: Error #2044: Unhandled SecurityErrorEvent:. text=Error #2140: Security sandbox violation: file:///mylayout.swf cannot load file:///slideshow_1.swf. Local-with-filesystem and local-with-networking SWF files cannot load each other. I know that it has something to do with the fact that one of the swf is local with filesystem and the other local with networking. but in my publish settings i told it to access local files only. but it didnt help. does anyone have an answer?

  • How to tell whether Code Access Security is allowed in library code

    - by Sander Rijken
    In .NET 4 Code Access Security (CAS) is deprecated. Whenever you call a method that implicitly uses it, it fails with a NotSupportedException, that can be resolved with a configuration switch that makes it fall back to the old behavior. We have a common library that's used in both .NET 3.5 and .NET 4, so we need to be able to tell whether or not we should use the CAS method. For example, in .NET 3.5 I should call: Assembly.Load(string, Evidence); Whereas in .NET 4 I want to call Assembly.Load(string); Calling Load(string, Evidence) throws a NotSupportedException. Of course this works, but I'd like to know if there's a better method: try { asm = Assembly.Load(someString, someEvidence); } catch(NotSupportedException) { asm = Assembly.Load(someString); }

  • How to inherit from DataAnnotations.ValidationAttribute (it appears SecureCritical under Visual Stud

    - by codetuner
    Hi, I have an [AllowPartiallyTrustedCallers] class library containing subtypes of the System.DataAnnotations.ValidationAttribute. The library is used on contract types of WCF services. In .NET 2/3.5, this worked fine. Since .NET 4.0 however, running a client of the service in the Visual Studio debugger results in the exception "Inheritance security rules violated by type: '(my subtype of ValidationAttribute)'. Derived types must either match the security accessibility of the base type or be less accessible." (System.TypeLoadException) The error appears to occure only when all of the following conditions are met: a subclass of ValidationAttribute is in an AllowPartiallyTrustedCallers assembly reflection is used to check for the attribute the Visual Studio hosting process is enabled (checkbox on Project properties, Debug tab) So basically, in Visual Studio.NET 2010: create a new Console project, add a reference to "System.ComponentModel.DataAnnotations" 4.0.0.0, write the following code: . using System; [assembly: System.Security.AllowPartiallyTrustedCallers()] namespace TestingVaidationAttributeSecurity { public class MyValidationAttribute : System.ComponentModel.DataAnnotations.ValidationAttribute { } [MyValidation] public class FooBar { } class Program { static void Main(string[] args) { Console.WriteLine("ValidationAttribute IsCritical: {0}", typeof(System.ComponentModel.DataAnnotations.ValidationAttribute).IsSecurityCritical); FooBar fb = new FooBar(); fb.GetType().GetCustomAttributes(true); Console.WriteLine("Press enter to end."); Console.ReadLine(); } } } Press F5 and you get the exception ! Press Ctrl-F5 (start without debugging), and it all works fine without exception... The strange thing is that the ValidationAttribute will or will not be securitycritical depending on the way you run the program (F5 or Ctrl+F5). As illustrated by the Console.WriteLine in the above code. But then again, this appear to happen with other attributes (and types?) too. Now the questions... Why do I have this behaviour when inheriting from ValidationAttribute, but not when inheriting from System.Attribute ? (Using Reflector I don't find special settings on the ValidationAttribute class or it's assembly) And what can I do to solve this ? How can I keep MyValidationAttribute inheriting from ValidationAttribute in an AllowPartiallyTrustedCallers assembly without marking it SecurityCritical, still using the new .NET 4 level 2 security model and still have it work using the VS.NET debug host (or other hosts) ?? Thanks a lot! Rudi

  • Spring-Security with X509?

    - by jschoen
    I am new to spring-security in general and am a bit confused. The project I am trying to integrate this with uses X509 certificates to identify users for signing in to the application. There are no usernames or passwords. We validate the certificates are good, and that they have been given access to our app. The question is how do I integrate spring in to this to get their roles using the X509 certificates? I have seen this: <http> ... <x509 subject-principal-regex="CN=(.*?)," user-service-ref="userService"/> ... </http> But I don't understand how this works. Will it still require something for a password? Or is the subject all it needs?

  • Jersey, Spring, Tomcat and Security Annotations

    - by jr
    I need to secure a simple jersey RESTful API in a Tomcat 6.0.24 container. I'd like to keep the authentication with Basic Authentication using the tomcat-users.xml file to define the users and roles (this is for now, like I said its small). Now, for authorization I'd like to be able to use the JSR 250 annotations like @RolesAllowed, @PermitAll, @DenyAll, etc. I cannot for the life of me figure out how to wire this all up together. I really don't want to go spring-security route, since I need something very simple at the current time. Can someone point me in the right direction.

  • Visual Studio / Visual Source Safe / Integrated Security / IIS 7

    - by Jason
    Using Visual Source Safe with IIS integration (the working dir is the IIS site) Visual Studio, pointed to the IIS site would load up the Web project. It would be under VSS control (have to check out files, etc). Recently, we had to switch to Integrated Security for our database connections from the web app. This means changing the impersonation of the IIS app pool (and anon authentication) to the impersonated account. Since I did this -- my project loads in Visual Studio, but it acts as if I'm not me, and the files aren't under source control anymore. I'm going to assume it's something with the pass-through from IIS to the VSS (as if you'll remember you had to add IIS_USERS to the VSS list of users). Even trying to add the impersonated account didn't work. Any ideas?

  • Spring security custom principal bean

    - by wuntee
    I have a web application that is set up to use the default ldap server/authentication manager/authentication provider/user service. I have another DAO that already does majority of the work that those do (besides the authenticating a user) using Spring-LDAP. My problem is that I want the principal to be of my own custom bean class. What is the simplest way to do this? Initially I was thinking to create a custom authentication provider, but since the default one does exactly what I want, there doesnt seem to be a need. I am thinking I just need to override whatever object actually returns the Principal bean. Is this possible, and able to be injected into the security ldap authenticator context?

  • security issue of Linux sudo command?

    - by George2
    Hello everyone, 1. I am using Red Hat Enterprise 5 Linux box. I find if a user is in /etc/sudoers file, then if the user run command with sudo, the user will run this command with root privilege (without knowing root password, the user runs sudo only need to input the user's own password in order to run a command with sudo). Is that correct understanding? 2. If yes, then is it a security hole? Since users other than root could run with root privilege? thanks in advance, George

  • Security flaw in this code approach

    - by Alec Smart
    Hello, Am wondering if there would be any security flaw in this approach. I am writing a piece of code which allows users to upload files and another set to download those files. These files can be anything. User uploads the file (any file including .php files), it is renamed to an md5 hash (extension removed) and stored on server. A corresponding mySQL entry is made. The user trying to download the file, uses say download.php to download the file where the md5 file is sent (with the original name). Is there someway in which anyone can exploit the above scenario?

  • Detecting browser capabilities and selective events for mouse and touch

    - by skidding
    I started using touch events for a while now, but I just stumbled upon quite a problem. Until now, I checked if touch capabilities are supported, and applied selective events based on that. Like this: if(document.ontouchmove === undefined){ //apply mouse events }else{ //apply touch events } However, my scripts stopped working in Chrome5 (which is currently beta) on my computer. I researched it a bit, and as I expected, in Chrome5 (as opposed to older Chrome, Firefox, IE, etc.) document.ontouchmove is no longer undefined but null. At first I wanted to submit a bug report, but then I realized: There are devices that have both mouse and touch capabilities, so that might be natural, maybe Chrome now defines it because my OS might support both types of events. So the solutions seems easy: Apply BOTH event types. Right? Well the problem now take place on mobile. In order to be backward compatible and support scripts that only use mouse events, mobile browsers might try to fire them as well (on touch). So then with both mouse and touch events set, a certain handler might be called twice every time. What is the way to approach this? Is there a better way to check and apply selective events, or must I ignore the problems that might occur if browsers fire both touch and mouse events at times?

    When using spring security, specifically with @notation; what is the proper way to access the principal in a Controller? Lets say the following is my controller, but I would like to access the principal in the secure() method somewhere... @Controller public class LoginController { @RequestMapping(value = "/login", method = RequestMethod.GET) public String login(ModelMap map, @RequestParam(value="fail" , required=false) String fail){ map.addAttribute("title", "Login: AD Credentials"); if(fail != null){ map.addAttribute("error", "Invalid credentials"); } return("login"); } @RequestMapping("/secure") @PreAuthorize("isAuthenticated()") public String secure(ModelMap map, String principal){ System.out.println(principal); return("secure"); } }

  • Image Uploading - security issues

    - by TenaciousImpy
    Hi, I'm developing an ASP.NET Web app and would like the user to be able to either upload an image from their local system, or pass in a URL to an image. The image can either be a JPG or PNG. What security issues should I be concerned about doing this? I've seen various ways of embedding code within JPG files. Are there any methods in C# (or external libraries) which can confirm that a file is a JPG/PNG, otherwise throw an error? At the very least, I'm making the directory which holds uploaded images non-browsable and putting a max size limit of 1mb, but I'd like to implement further checks. Thanks for any advice.
