Security :: Password Field Cleared - Security Threat?

Jul 21, 2010

I'm having the problem of my password fields being cleared when a postback occurs on a dropdownlist selection change.

Is it a security threat to fix it with this...

protected void Password_PreRender(object sender, EventArgse)
{
(TextBox)sender).Attributes["value"]
= ((TextBox)sender).Text;
}

Security :: Migrating Existing Cleat Text Users Password To Hashed Password Membership Provider?

Sep 9, 2010

I had been trying to solve this but there is a hidden key i wish someone point me to.

I had a simple membership database with users in first the Membership Provider configured for clear password to retrieve the original password .

Now a new requirement say that the password must be hashed and reset .

I configure the Membership password to hash , and Implemented the Reset Password Module.

My problem is as follow.

If the user is new registered user with the new configuration the password and the security answer is hashed.

also when I go and reset the password it continue to be hashed.

Now I thought that with new configuration if any previous user with clear text configuration , If he use the password Reset module , because my configuration now is hashed , I expected that the new password and security answer will be hashed . what happen is old user continue in clear text even if the configuration is hashed. so If I had new users everything is fine.

old users Membership Provider somehow know they had been stored in clear text and it keep change password and security answer in clear text . If I delete this user and create it , Membership Provider understand that everything will be hashed. I need to know how it know this , I need to migrate users not to delete and recreate users .

Also if there are no solution for that , I wish Microsoft Consider it in future cause it is a real user scenario, that can happen imagine a business system that related to membership user Id , deleting users and recreate them is not a solution .

Security :: Trying To Log In After A Mispelled Password?

Dec 1, 2010

I've implemented the Membership & Roles infrastructure of ASP.Net and it generally works well [in my ASP.Net 3.5 C# project].

However, testing is revealing something rather peculiar:

Start the web appDeliberately enter the wrong passwordTry again, this time with the correct password - fails to loginTry once again with the correct passwrod - login is successful Clearly this can't be the way it's supposed to work! I'm curious whether anyone else has observed this phenomenon, and if so, how did you fix it?

Security :: Cannot Set Password For New Login

Jun 23, 2010

I am having a big problem trying to set the password for a login (MS SQL Server Management Studio).

I can create a new login and specify a password. Hitting "OK" reports no errors. Opening the newly created login shows that windows has automatically changed the original password to something else (I can tell because of the password length).

I have no idea why this is happening and have even tried reinstalling SQL.
