Hi there I am developing a web app and I am using Spring Security. In the app the user can change his/her details (username, password and some other fields). I am using a custom User Details Class for this and my Spring Security configuration is the default (keep in mind no cache method is declared, so I suppose NullUserCache is used). All the user records come from DataBase using JDBC Connector (MySQL).
Now when a user changes his/her info or/and username-password those changes update the corresponding columns in DataBase. So now the DB is updated. Because I have not implemented setters in my Custom User Details Class, I force the user to logout log out automatically. But now he/she can login using both the new username and the old one.
Suppose now that the user changed something on the other fields (for example if the age was changed from 20 to 21). When user logins using the new username I can see 21. If user logins using the old username I can see 20!.
I guess Spring Security now creates a new User (during login) which didn't exist and the old one is never removed!
So after reading many posts in the web and trying the corresponding solutions I 'm still unable to fix that.
What I have used (in the controller that is responsible for account editing):
if (authenticate != null){
new SecurityContextLogoutHandler().logout(request, response, authenticate);
}
SecurityContextHolder.getContext().setAuthentication(null);
SecurityContextHolder.clearContext();
What I understand and believe is that Spring Security holds somewhere (I thought User Cache) the username, maybe along with the password and now it sees the old username as a different User. The only way to prevent this from happening is to restart the app. After restarting the user only logins using the new username.
Is there any way I can remove that "user"-username? Any suggestion would be usefull, I am really confused and the only case close to mine was this but his problem was with the oracle connector using connection cache..
UPDATE problem tracked down to a problem inside loadbyusername method..read more on the 14th comment below :)
Happy coding!
I finally found the source of that problem..black hole closed. Credits #Jebil and #Robin Winch for their help!
Well everything worked as it should except the fact that the HashMap on the rensposible for the login DAO, was never cleared..so after every successful login attempt the HashMap returned was appended and so after every username update, it contained both old and new values..solution was simple..before accessing the DB HashMap should be cleared!
Happy dividing by 0 :P

this question has been posed in many flavours, but no one fits my needs.
I'm working on a partially complete Razor project; the original developer has left our office, and he wasn't much concerned about securing password fields, as he left all of them in clear.
These passowrd fields authorize several aspects (Ftp primary and secondary access, Ftp on AS400 and mail sending), so nothing related with login/submit forms. When I changed these fields from text to password, they revert to blank fields, regardless the content of the View Model, and this should be the correct behaviour, as per the numerous answers I've seen googlin around.
My problem is this: the user needs to know at least if a password has been configured (seeing a string of * or any other mask character the browser use), so I need to show him that value to let him know if the service is configured, and the best would be to let him also reveal the password to check if it's correct. The option to not update the particular field in the DB if it's left blank is not an option.
This site works only on Intranet, so there is no concern about hackers monitoring the connection or similar.
I've tried all (I think) the possible combinations, including building the input element manually through html, using the #Html.TextFor and #Html.PasswordFor helpers, decorating the corrisponding member in the view model with [DataType(DataType.Password)]. The data is binded when the page is loaded, so no ajax calls help me retrieving data.
I'm relatively new to Razor, as my last two projects are entirely in PHP.
Thanks for any suggestions.
Ok, no other solution found than issuing an ajax call to a dedicated HttpGet controller method to retrieve only the password fiels, then populating the dedicated fields when the controller returns the object containing all the password I need.
How can I show the decrypted user password in an edit form?
I am using DefaultPasswordHasher for Hashing passwords while registration of users using this:
protected function _setPassword($password) {
return (new DefaultPasswordHasher)->hash($password);
}
It works well and the password is encrypted...
But when I used user table in view page and edit page it shows the encrypted password. So how can I decrypt the password in the controller and when edit page it also decrypt and store in database in CakePHP 3.x?
Simple answer is: You can't
The whole point of hashing is that you cannot reverse engineer the password. So that when your database is hacked or leaked no harm can be done with the passwords.
Any website showing you your own password has a severe security problem and I would not use it.
There is also no point in showing the encrypted password. Editing a password is not needed, you just overwrite the old one (when they can still provide their old one ofc), and if one of your user forget their own password you should provide them with a recovery system using their email for example.
I am new with Node js.I create a application with express framework and mysql database.i did add user and login.That's working fine but now am trying to reset my password with one time url.please help me.
This question doesn't contains any code snippets, any specific logical flow. If you are able to post some code, the you will be getting more accurate answer. Anyway I will try to provide a broad logic.
From your question, I understood that you know how to use expressjs routing, connecting to mysql from expressjs etc.
So for resetting password, you need to send a link with a unique token to the user when user clicks on a forgot password/reset password link. Store this tocken in a separate mysql table with a created time stamp. When user clicks this url which send to his emailid, check with the token entry in db table and make sure it is not expired, and show the user a reset password interface. After resetting, remove the token stored in the db table.
Here is the problem: I have a KB Called APP1 that will execute an WebService of an Identity Provider (centralizes all the logins/sessions for different applications) that will return true if there is a logged user in current WebSession that has been granted to access the Application or false otherwise. When I create an web panel at the same KB as the Identity Provider, it works just fine, I get TRUE when there's a logged user, and FALSE when there's not. But when I call it from APP1 it always returns false, I believe that the problem is because the WebSession won't work properly when called through an WS. Any ideas of how to solve it?
My first advice is to try using GAM Single Sign on (X Evolution 3)
WebServices should be Stateless. I think that using the Database instead of WebSession could do the job.
Nonetheless, in order to call a restful WebService you will have to do something more complex as dealing with CookieContainers as stated in the following link.
Consider this solution:
User tries to access App1
There's no web session (App1 doesn't know who is connecting)
App1 redirects User to an IdentityProvider's special login page
If User is not logged, it provides credentials and logs in
IdentityProvider has a session for the user (it knows who is connecting), then it redirects to the referer, appending to the url an encrypted userid parameter.
App1 decodes the parameter, now it knows who is connecting.
App1 saves the userid to the web session, now the user is authenticated
App1 and IdentityProvider must share an encryption key.
Consider that if the encryption key gets compromised or cracked anyone can impersonate another user.
Depending in how secure you want your system to be, you should study other security issues:
every time the user connects it's encrypted login is the same an it shows in the url, it can be easily solved adding a nonce or salt.
The system could be abused generating multiple requests until it gets a valid encrypted userid. It can be mitigated using a large Salt and/or blocking multiple attempts from the same source.
Note that this isn't a tested protocol and I didn't study the security in depth. I got some inspiration from OpenId, but this is a simplified protocol and I could be missing security holes.
First Project: Spring3, Security3, Hibernate, MYSQL - How to install user tracking into database
I am working on my first project with Spring3, Security3, Hibernate, MYSQL.
I have the system working great I use Spring3 and Security3 goign to MySQL for the login and
using Spring3 MVC, Hibernate and MYSQL for system data.
I have a number of questions. Once I login does Spring Security save the user object somewhere that I can have
Hibrernate access it. I want Hibernate to put the user name or role into each insert to the database so as
I do my searches the system knows to only show data for that user and only that user?
this somes like it should be easy. Spring should be saving the user somewhere the hibernate can access.
please help me out
Once the user is authenticated, you can access the user's authentication session details:
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
SecurityContext will allow you to grab the Authentication object, and from that you can retrieve the principal (an object representing the authenticated user), roles, etc. You could inspect this information and determine what data should be stored/displayed for each user.
If you can add a request filter or interceptor (the vocabulary may vary between frameworks), you could probably make these security checks abstract/generic enough to be applied across your entire web app (instead of adding a few lines of code to every resource method you're attempting to secure). Either way, SecurityContext should get you closer to what you want.
