VERIFY ADVISORY:

CRITICAL:
Highly critical

IMPACT:
Security Bypass, System access

WHERE:
>From remote

SOFTWARE:
Sugar Suite 3.x
http://secunia.com/product/6400/
Sugar Suite 4.x
http://secunia.com/product/9921/

DESCRIPTION:
rgod has discovered a vulnerability in Sugar Suite, which can be
exploited by malicious people to bypass certain security restrictions
and compromise a vulnerable system.

The vulnerability is caused due to various scripts in the "modules"
directory incorrectly protecting against direct web access by
checking the global variable "sugarEntry". This can e.g. be exploited
to include arbitrary files from external and local resources by
defining the "sugarEntry" parameter and other parameters.

Successful exploitation requires that "register_globals" is enabled
and that support for ".htaccess" files is not enabled (the included
.htaccess file requires Apache with the mod_alias module).

The vulnerability has been confirmed in version 4.2.0a. Other
versions may also be affected.

SOLUTION:
Set "register_globals" to "Off" or restrict web access to the
"modules" directory.

PROVIDED AND/OR DISCOVERED BY:
rgod
