Here is the patch. Storing the password in SHA1 salted from and generating new salt (better than MD5 without salt).

EDIT: uploaded improved patch

WOW! What?

Out of the box FUDforum stores passwords as plain text??

Ok looking in the DB for my forum (v3.0.3) the passwords are hashes of some sort and there is a salt column in the users table....but it is NULL for everyone.

So the devs of FUDforum provised a salt table but haven't implemented it and your patch actually uses salt for each user?
Can this patch be applied to an already running forum? How to the existing passwords get along with this patch?

EDIT : FUDforum does not store passwords in plain text.

FUDforum supports 2 authentication models: straight MD5 hashing of password, or SHA1 hashing of (password concatenated with SHA1 hash of salt). If the salt is present, FUD assumes SHA1, otherwise plain MD5.

The fud_update_user and fud_add_user functions (which are intended for integration, and are not directly called by FUDforum) were simply wrongly coded and stored passwords in plaintext (thus login would not work, since it expects an hash). I just made sure that they use the most secure form possible, although it is slightly more expensive (two hashes for every authentication instead of one).

Umm so this patch is not needed for systems without funcitonal issues and hashed passwords?

It seems my forum is not using salt, so I would like it to. Do I wait for the next update??

Indeed, it is not needed on a functional forum. It is needed only if you want to manipulate user data via the API.

I have not yet a full understanding of the inner workings of FUD, but one of the things I wish to do is have the salt be used by default. Look forward to it in one of the upcoming versions.
