Security :: Authenticate Users By Request.UrlReferrer?

Sep 25, 2010

I am working on an app where users are only allowed access if they click through from certain URLs. I.e. I need to authenticate by using the referral url and I am using
Request.UrlReferrer to achieve this.

I am guessing that the Request.UrlReferrer can be tampered with by malicious users to gain access...

C# - Use Request.UrlReferrer When Determining Referrals?

Sep 9, 2010

I came upon an interesting discussion with my team around the use of HttpRequest.UrlReferrer and wanted to solicit feedback from the community. According to the W3C spec:

The Referer[sic] request-header field allows the client to specify, for the server's benefit, the address (URI) of the resource from which the Request-URI was obtained (the"referrer", although the header field is misspelled.) The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. It also allows obsolete or mistyped links to be traced for maintenance. The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard.as input from the user keyboard.

The Request.UrlReferrer object does the work of converting referral strings that contain well formed URIs to an object with properties on every request. According to our logs there are requests that come in that contain invalid data in the referral such as:

localhost
app:/BeamBackTest.swf
app:/multtiple.swf
app:/AFriendFeed.swf
ALToolBar
app:/index.html
mhtml:file://C:Documents+and+SettingsUserDesktoporacleWhat+is+a+View+in+Oracle+-+Stack+Overflow.mht

Using Request.UrlReferrer would mean the above cases would be NULL. Is it better to discard the invalid data based on the W3C spec by using Request.UrlReferrer or preserve it by using Request.ServerVariables["HTTP_REFERER"] even though the data may be interesting, but potentially useless.

Configuration :: Migrating The Request.UrlReferrer.ToString() To The Web.config File

Jan 10, 2011

I have the following code in 'main.cs' file where I am checking for a condition

protected void Page_Load(object sender, EventArgs e)
{
if (Request.Form.Get("task") != null && Request.Form.Get("postToURL") != null &&
Request.UrlReferrer.ToString().Substring(0, 31).Equals("http://cs.astra.co.in:4040"))
{
ASCIIEncoding encoding = new ASCIIEncoding();
<SO ON>

Instead of checking for the URL [URL] in 'main.cs', Can I check for the same condition in the 'web.config' file ? If so, How can I do that ?? Is there any way to transfer the part -- Request.UrlReferrer.ToString().Substring(0, 31).Equals[URL] -- into the 'web.config' !!

Use SharePoint To Authenticate Users On Separately Hosted Website?

Oct 27, 2010

The behaviour I would like is for a user to be able to visit a custom built website and if they are already authenticated against sharepoint for the custom website to know who they are and give them various rights. If they are not recognised by sharepoint then I would like them to login to sharepoint and be directed back to the custom website. Sharepoint picks its users and groups up from Active Directory. I don't know much about the internals of the server, but the custom one will be in a separate domain (I think) though I have full control over the custom and moderate control over the SP infrastructure.

Using Active Directory To Authenticate Users In WWW Facing Website

Mar 13, 2010

I'm looking at starting a new web app which needs to be secure (if for no other reason than that we'll need PCI (Payment Card Industry) accreditation at some point). From previous experience working with PCI (on a domain), the preferred method is to use integrated windows authentication which is then passed all the way through the app to the database using kerberos (so the NT user has permissions in the DB). This allows for better auditing as well as object-level permissions (ie an end user can't read the credit card table). There are advantages in that even if someone compromises the webserver, they won't be able to glean any/much additional information from the database. Also, the webserver isn't storing any database credentials (beyond perhaps a simple anonymous user with very few permissions for simple website config)

So, now I'm looking at the new web app which will be on the public internet. One suggestion is to have a Active Directory server and create windows accounts on the AD for each user of the site. These users will then be placed into the appropriate NT groups to decide which DB permissions they should have (and which pages they can access). ASP.Net already provides the AD membership provider and role provider so this should be fairly simple to implement. There are a number of questions around this - Scalability, reliability, etc... and I was wondering if there is anyone out there with experience of this approach or, even better, some good reasons why to do it / not to do it.

Authenticate Users Using DotNetOpenAuth With An Active Directory Provider?

Dec 4, 2010

I am trying to integrate authentication for a cloud-based application with an Active Directory forest behind my cilent's firewall.

I am a Python developer from the open-source world... needless to say, .NET is not my forte and I'm not familiar with authentication technologies provided by IIS/WIF/etc.

I have installed DotNetOpenAuth and gotten the sample MVC OpenID provider working with the included ReadOnlyXmlMembershipProvider.

I have scoured Google for a sample config/implementation or any documentation at all that describes the appropriate membership provider to use. The only thing I have found are hints - "It's included out of the box," or "create a .NET app that authenticates off of AD and expose OpenID."

How can I query off my client's AD? Is there a provider included with DNoA?
