Hello,
I heard that a new phpnuke vulnerability has been discovered, which allows the attacker to embed malicious JavaScript code in the private messages that execute XSS attack. So that when the admin opens the message, he will send his cookie with the encoded password.
I'm running phpnuke 5.4. I want this bug to be fixed, and make my web site much secure for guests. I checked the phpnuke website, but, I couldn't find anything that deals with this. Any suggestions?
I have not heard nor did find anything about this vulnerability. Do you have any source or more information ?
The latest vulnerability for PHP-Nuke I found was (not related to what you tell):Quote:

And closest vulnerability I found (similiar but not the same?):Quote:
CAN-2002-0483
Summary: index.php for PHP-Nuke 5.4 and earlier allows remote attackers to determine the physical pathname of the web server when the file parameter is set to index.php, which triggers an error message that leaks the pathname.

Severity: Low
And another similiar vulnerability:Quote:
CAN-2001-0911
Summary: PHP-Nuke 5.1 stores user and administrator passwords in a base-64 encoded cookie, which could allow remote attackers to gain privileges by stealing or sniffing the cookie and decoding it.

Severity: High
Can it be some of these older vulnerabilities you have heard about ?Quote:
CVE-2001-0001

Thanks a lot micael,
This is my source:

My site is still vulnerable, and I want this bug to be fixed, but it seems to me that they don't supply a patch for fixing this issue.
This is exactly what I've heard about:

Are you sure that the latest version of PHP-Nuke 5.6 still are vulnerable ?
The release date of PHP-Nuke 5.6 is 04-Jun-2002 and the vulnerability from 21-November-2001 and they are speaking about PHP-Nuke 5.1. Since this was (is?) a high severity vulnerability would I be surpriced if they not have fixed it during this time.
This is quoted from the article you provided the link to. Its a old article acording to the date and this may already been fixed? Anyway I did some more investigations and found a similiar article were they did describe cookie password and a possible solution.Quote:

Aurélien Cabezon a découvert une vulnérabilité sur PhpNuke qui permet, en utilisant aussi une vulnérabilité récente d'Internet Explorer de dérober le login/passwd admin d'un site sous phpnuke Ã* son proprietaire.
My advice send a e-mail to [email protected] and ask status of this and upgrade to PHP-Nuke 5.6 and PHP 4.2.2 if you not already are using it :).Quote:

Simple answer, PHP Nuke support PHP3 and PHP4 unless the admin want to used session then its need PHPLIB which is troublesome in most cases. Unlike PHP4 which support Sessions, however some people still using PHP 3.0.x which will not being able to do it.
Again I like the idea, and maybe you should start a new addon which can be hosted on our CVS at http://sourceforge.net/projects/nukeaddon/
Hope to see you there. You can also email me at [email protected] if you need to talk more detail.

Yea 5.6 is vulnerable too.
I would suggest to upgrade to 5.6 just because its latest (besides 6beta) and then go to http://www.phpnuke.org/modules.php?n...download&cid=9 and select
