Hello,

I'am trying to learn more about SQL INJECTION by a ASPX (ASP NET) websites.

I already know how to hack/test a PHP site with Sql-Injection.

I tried to do some sql-injection by this URL:

http://www.example.com/app/article.aspx?id=1

When I set ?id=1' The website display a error like this :

Code:
Server Error in '/' Application.

Input string was not in a correct format.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.FormatException: Input string was not in a correct format.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Stack Trace:


[FormatException: Input string was not in a correct format.]
Microsoft.VisualBasic.CompilerServices.DoubleType.Parse(String Value, NumberFormatInfo NumberFormat) +195
Microsoft.VisualBasic.CompilerServices.IntegerType.FromString(String Value) +97

[InvalidCastException: Cast from string "1'" to type 'Integer' is not valid.]
Microsoft.VisualBasic.CompilerServices.IntegerType.FromString(String Value) +212
ASP.article_aspx.__Render__control1(HtmlTextWriter __output, Control parameterContainer) +78
System.Web.UI.Control.RenderChildren(HtmlTextWriter writer) +27
System.Web.UI.Control.Render(HtmlTextWriter writer) +7
System.Web.UI.Control.RenderControl(HtmlTextWriter writer) +243
System.Web.UI.Page.ProcessRequestMain() +1926

Version Information: Microsoft .NET Framework Version:1.1.4322.2407; ASP.NET Version:1.1.4322.2407


After I do that, I set this in the URL ?id=1 order by 1000-- But the website keep display me the same error as above.

Can someone explain to me if this website is vulnerable? and how do I process a sql-injection to this website (to a aspx website).

Thank you ! 8)

There is no SQL Injection here. Script is trying to convert your attack string to integer and fails. Look for other places - for example search functionality.
