CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

DESCRIPTION:
Santiago Cortes has reported a vulnerability in Sugar Sales, which
can be exploited by malicious people to compromise a vulnerable
system.

Input passed to the "moduleDefaultFile" array is not properly
sanitised, before it is used to include files. This can be exploited
to include arbitrary files from external and local resources.

Example:
http://[victim]/index.php?module=Home&moduleDefaultFile[Home]=[file]

Successful exploitation requires that "register_globals" is enabled.

SOLUTION:
Set "register_globals" to "Off".

Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
