A Potentially Dangerous Request.Form Value Was Detected

Jun 23, 2010

On a windows 2008 web server, I get the following error whenever posting a form containing html tags in textboxes:

A potentially dangerous Request.Form value was detected from the client (widget$txtText="

This is a common error and you fix it by either doing Page ValidateRequest = false or in the web.config with pages validaterequest = false. However, on this specific server, it completely ignores the validaterequest = false and throws this exception anyway. Has anyone seen this behavior before and know what else I can do to prevent this error? I've seen it in 2 web apps now on the same server, it's really weird.

Unable To Submit Form With Html Characters - Potentially Dangerous Request Detected

Oct 12, 2010

I have a form that a user fills out and can input html or other text into a textarea. I have the validaterequest attribute set to false on the page. However, when I submit the form with any html characters it bombs saying that it detected the potentially dangerous request field and to make validaterequest=false. I've already done this so I'm not sure why it's not working. I've done this many times before and never had this problem. Anyone run into this before and if so, is there a fix? I don't want to update my web.config and apply it site wide.

A Potentially Dangerous Request.Form Value Was Detected / Can't Set ValidateRequest="false"

Aug 16, 2010

I'm using a php script to http post some xml files to a .net URL.

When I submit I get the response:

A potentially dangerous Request.Form
value was detected from the client
(<?xml version="...UTF-8"?> <!DOCTYPE
cXML SYSTE...").

Description: Request Validation has detected a potentially dangerous client input value, and
processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

As I'm not using .NET I can't set ValidateRequest="false" in web.config.

Do I need to sanitize my xml before submitiing? How can I do this?

C# - List Of Input Values Which Will Cause The "A Potentially Dangerous Request.Form Value Was Detected" Error

May 3, 2010

I know the < and > characters will cause this error, but what other characters/inputs will cause this error?

I'm testing for this error in the Global.asax, and reridrecting to an error page where I want to list all possible values which cause this error, so the user can go back to their page and get rid of them.

I've done some googling, but all I see so far are the < and > characters...surely there are more out there.

C# - Auto Encoding Text Inputs - Error "A Potentially Dangerous Request.Form Value Was Detected"

Nov 23, 2010

To prevent my application from crashing with the error "A potentially dangerous Request.Form value was detected...", I just turned page validation off. I want to revisit this and solve it correctly. Is there a good strategy for this? If people are entering '<' and '>', I think the only way to save their data is to encode it via Javacript. I have tried catching it in the code-behind, but it becomes too late. I am thinking of inheriting the textbox and auto encode/decode the input with client scripts. I also have to think of all the angle brackets that are already saved in my database.

No Querystring Logged In IIS Log On "A Potentially Dangerous Request.QueryString Value Detected"

Mar 5, 2010

I'm intermittently seeing this exception being thrown:

A potentially dangerous Request.QueryString value detected

However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.

How could this be? Are "dangerous" query strings being stripped from the log or something?

Web Forms :: Getting The "Potentially Dangerous Request Form..." Error Even With ValidateRequest Set To False?

Jun 25, 2010

I have an app that was originally running fine in ASP.Net 3.5, using the ValidateRequest set to false to allow HTML to be saved from a rich text box. However, after converting the app to 4.0, I am getting the Potentially Dangerous message, even though both the page and web.config have the value set to false.

I went into the page and created a PagesSection object and checked its value and then set the value to false. Everytime the page is hit (postback or new) the value is always returned as true, until I set it to false. Not sure why it is reverting to true.

C# - Are Conditions For Raising "potentially Dangerous Request.Form Value" Errors Dependent On .NET Configuration And Version?

Jul 7, 2010

I'm testing a Tiny_MCE plugin for BlogEngine.NET extension I wrote earlier and I keep receiving the following error message whenever I use my own extension or the extremely popular SyntaxHighlighter extension which both have similar behaviors and both implement Tiny_MCE plugins:

Url :
'http://localhost/admin/Pages/Add_entry.aspx'
Raw Url : /admin/Pages/Add_entry.aspx[code]...

My question is thus: although I receive this error on my local environment (IIS 7.5 ASP.NET 4.0 Integrated App Pool) I receive no error whatsoever on my live environment (IIS 7.5 ASP.NET 3.5 SP1/ 3.0 / 2.0.) Additionally whenever I test the extension using debug mode in Visual Studio 2010 and run the site off of a separate instance I don't receive this error.I'm almost certain that the fact that this issue only occurs on my localhost IIS instance indicates that it's a configuration issue or a behavior specific to ASP.NET 4.0, but I don't know what exactly.

Web Forms :: Get The Error "A potentially Danger Request.Form Value Was Detected From The Client (txtCodeExtract=" Etc")

Sep 28, 2010

I am writing a database to store code extracts which will make our life easier at work, I have a text box which retrieves HTML characters, I have no problems in displaying them, however if I click the edit button to amend text I get the error "A potentially danger Request.Form value was detected from the client (txtCodeExtract=" etc").

I have added ValidateRequest="False" to the main form however, when I now click the edit button the textbox wipes out all the text.

I have tried using the Server.HTMLEncode(txtCodeExtracts.Text); or Decode and HttpUtility.HTMLEncode or Decode but the textbox still clears.
This is a web app using Visual Studio 2008

Why Using A URL Containing A Colon Considered As A Potentially Dangerous Request

Jul 27, 2010

(probably a bot) sent a request with the following URL to my ASP.NET 4.0 web forms application (running on IIS 7.0):http://ipaddress-of-my-applications-domain/bla1.bla2.bla3.bla4.bla5:)This caused an System.Web.HttpException. I received a logging email from ASP.NET HealthMonitoring I had configured, telling me:A potentially dangerous Request.Path value was detected from the client (:).

System.Web.HttpRequest.ValidateInputIfRequiredByConfig()
System.Web.HttpApplication.PipelineStepManager.ValidateHelper(HttpContext context)

Why is a colon in the URL "potentially dangerous"? What dangerous things can be done with such a URL? Do I have any security hole here I am not aware of?

Security :: Potentially Dangerous Request When Packing Session State?

Mar 31, 2010

I'm writing a product management system for a website. As an administrator defines product details, those details are stored in the Session so that fields remain populated as the user navigates across multiple pages. One of these fields is a "RichTextBox" that allows the user to define a product description with rich text.

Attempting to pack the contents of this rich text box into a Session variable raises the following Server Error:

A potentially dangerous Request.Form value was detected from the client (ctl00_ContentPlaceHolder1_RichTextBox1_tbxRichContent="<b>asdf</b>").

The offending line of code is as follows:

Session["NewProductDescription"] = HttpUtility.HtmlEncode(RichTextBox1.Text);

I thought HtmlEncoding would solve the problem, but it did not.

HttpHandlers / Modules :: Hanging Request.Form Collection Values / Request.Form Collection Is Readonly

Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.

Get Request.Form.Item By Matching Request.Form.Key?

Jul 6, 2010

My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.

How can I get the regular key name working?

Visual example from the immediate window:

I want to use:

? request.Form.Item("stationIdea")

but it won't work because the key is:

ctl00$content_innovation_body$stationIdea

as retrieved by

? request.Form.Keys("4")

so only this works:

? request.Form("ctl00$content_innovation_body$stationIdea")
