Charles Nelwan has discovered a vulnerability in the a6MamboCredits component for Mambo, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to the "mosConfig_absolute_path" parameter in administrator/components/com_a6mambocredits/admin.a6mambocredits.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 2.0.0 and has also been reported in version 1.0.0. Other versions may also be affected.
Edit the source code to ensure that input is properly verified.
Set "register_globals" to "Off".
