CRITICAL: Highly critical

IMPACT: System access

WHERE: >From remote

SOFTWARE: Coppermine 1.x (component for Mambo) -- http://secunia.com/product/11551/

DESCRIPTION: k1tk4t has discovered a vulnerability in the Coppermine component for Mambo, which can be exploited by malicious people to compromise a vulnerable system.

Input passed to the "mosConfig_absolute_path" parameter in components/com_cpg/cpg.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from external and local resources. Successful exploitation requires that "register_globals" is enabled. The vulnerability has been confirmed in version 1.0. Other versions may also be affected.

SOLUTION: Edit the source code to ensure that input is properly verified.
Set "register_globals" to "Off".
