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

[raphael.huck () free fr]

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));
