We have only just become aware of this report and will investigate to see whether this also affects Joomla!

Initial thoughts are that since it is specifically referenced as affecting only Mambo 4.6 RC and not earlier versions of Mambo, than it is likely only to affect the latest installment of Mambo. That is the vulnerabiity is possibly due to a change made in Mambo 4.6.

Note however, this is only speculation at this stage. A definiitive answer can only be made with further investigation.

Note that this report has not yet been confirmed by Team Mambo officials as being an actual vulnerability

Had a quick look.
I think your safe when you make the following changes:

open /components/com_weblinks/weblinks.php, find:

Code: Select all

/**
* Saves the record on an edit form submit
* @param database A database connector object
*/
function saveWeblink( $option ) {
	global $mosConfig_mailfrom, $mosConfig_fromname;
	global $database, $my;

	if ($my->gid < 1) {
		mosNotAuth();
		return;
	}

replace it with:

Code: Select all

/**
* Saves the record on an edit form submit
* @param database A database connector object
*/
function saveWeblink( $option ) {
	global $mosConfig_mailfrom, $mosConfig_fromname;
	global $database, $my;

	if ($my->gid < 1) {
		mosNotAuth();
		return;
	}
	
	// security check to see if link exists in a menu
	$link = 'index.php?option=com_weblinks&task=new';
	$query = "SELECT id"
	. "\n FROM #__menu"
	. "\n WHERE link LIKE '%$link%'"
	. "\n AND published = 1"
	;
	$database->setQuery( $query );
	$exists = $database->loadResult();
	if ( !$exists ) {						
		mosNotAuth();
		return;
	}

Than make sure no link exists in your menu to 'index.php?option=com_weblinks&task=new'.
Ofcourse this will not allow users to submit weblinks, but this will do for a lot of websites.

Posted: **Mon Jun 19, 2006 9:48 am**

If you do want to allow users to submit links, you can make the following modification:

Find (in the same file as above):

Code: Select all

// until full edit capabilities are given for weblinks - limit saving to new weblinks only
	$row->id = 0;

Replace with:

Code: Select all

// until full edit capabilities are given for weblinks - limit saving to new weblinks only
	$row->id = 0;

	if(stristr($row->title, 'SELECT') && stristr($row->title, 'FROM') && stristr($row->title, 'WHERE')){
	  echo "<script> alert('Illegal characters in title'); window.history.go(-1); </script>\n";
		exit();
	}

This will pop up an alert if the words 'SELECT', 'FROM' and 'WHERE' are used in the weblink title (which the exploid does).

Note:
I don't know if Joomla is vulerable to the exploid, the code posted above should protect you from the exploid if it should work.

A fix for the Mambo vulnerability has been posted on Mambo Guru http://forum.mamboguru.com/showthread.php?t=264
This patch is for 4.6 RC1 and another for 4.5.3h/4.5.4 is coming. It is possible that the vulnerability affects older versions of Mambo as well.
When the 4.5.3h/4.5.4 patch is posted on the forum it may be useful for Joomla devs to look at (we are not going to be presumptious so wont be posting a fix for 1.0.9

)

Posted: **Mon Jun 19, 2006 3:46 pm**

This security threat is confirmed in the Joomla! codebase and affects all previous versions of Joomla! including 1.0.9

It is being listed as a [HIGH LEVEL] threat as it can lead to the possibility of confidential user password access information being gained.
Note that this vulnerability is only exploitable by sites that have registered or above frontend access to a site. If you have a site that does not have frontend access, you should be safe from this vulnerability.

An official fix is pending and will be released shortly. However, we are currently examining the core to ensure no other similar vulnerability exists elsewhere in the system.

Posted: **Mon Jun 19, 2006 3:51 pm**

Ifnyou have frontend access but NOT the ability to submit weblinks are you vulnerable?

I'm sure Mambo users apprieciate this fix being made available.

However, it should be noted that you cannot access the attachement (or any attachment) on the mamboguru forums unless you are registered on the forums - this may limit the access to the fix.

It may be something you might wish to blog about on the guru site to increase its visiblity - but I understand this may be seen as trouble making

Unfortunately yes you are still vulnerable.

However, if you impelment websmurf's suggestion here:
http://forum.joomla.org/index.php/topic ... #msg366017

This will stop this hole in this instance, where you do not allow weblinks submission.

Sadly, this is the way it has to be

There have been abuses of copyright and until certain parties stop stripping copyright out of code, we are not comfortable with just putting the patches into our file download area. Any Mambo users who don't want to register on the forum (and there are many who don't want to be seen to be there, which is why we allow people to login as hidden users) can email me and I will send you the patches.

This is unfortunate, anway I'm sure there are users who appreciate the effort.

Securityfocus is listing another security issue related to "IncludePath Remote File Include Vulnerability" here: http://www.securityfocus.com/bid/18363/. Not sure if this has been addressed yet or not.

Unfortunately, securityfocus.com doesn't provide much information. If that listing is based on http://www.securityfocus.com/archive/1/436707 (they link it as a reference), then that's not going to work. I would say that's a hoax.

Yes we are aware of this report and as pointed out by [friesengeist] there is so little information it is simply not possible to test the veracity/accuracy of the report.

We have even tried to contact the original reporter via the email listed.

However, at this stage we have to list this report as being UNCONFIRMED and possibly false.

Of course if more information can be provided we will examine the issue again.

this post?

I know that the [mod note: removed] stuff does work, I also confirmed yesterday that Joomla is vulnerable. However, I didn't want to make the details public, so I send them to the core devs per mail.
