A very serious bug has been found in _all_ versions of Pligg. We have a patch available here. We advise you to apply this immediately.

For 9.0, 9.1, 9.5 versions
1) upload the upgrade_login.php into your root Pligg folder. Not the install folder. Then open the file in your browser. If you have *any* errors, let us know as many details as you can so we can help you fix it.

2) upload the appropriate login.php file. Rename your existing /login.php file to /login.php.bak, rename the new one you just uploaded to /login.php. Please note, this is NOT the /libs/login.php file.

3) If you can login / logout without any problems, then delete the .bak file.

We expect to release a beta 9.5.1 (security update) before the end of the month to fix this and a few other bugs we found.

Thanks.

ps: if you want to manually edit your login file, look here.

What exactly was the problem, and how bad of a risk is it to not apply this update?

(These questions should be addressed in all Security updates if possible)

Pls check here Pligg Security Vulnerability - Password Change Request, there was a security hole which had the risk of site takeover - but thankfully Ash got it fixed sooner.

Pls take some additional precautions also as outlined in that thread to protect your site better.

One point I'd like to share is the note to change /login.php to /login.php.bak

I wouldn't leave any .bak extension files of any kind on a server. I've seen those exploited by hackers before.

Good point, update my instructions, thanks

What about earlier versions of Pligg? I am running a modified 8.2.

For 8.2 follow the same instructions but use these files.

Okay, I did as instructed but when I brought up the upgrade_0.8.2.php file in my browser nothing is displayed but a blank white page. I am using FireFox. Is that what is supposed to happen? I was expecting at least a "patch applied" message.

I just replaced the file. Please try it again. thanks

Just thought I would throw this out there. As a Pligg community lets not throw this up on DIGG or any other information source that will attract hackers attention . If I am totally wrong I apologize
