http://secunia.com/advisories/15893/

CRITICAL:

SOFTWARE:
EasyPHPCalendar 6.x

DESCRIPTION:
Mafia_Boy has reported a vulnerability in EasyPHPCalendar, which can
be exploited by malicious people to compromise a vulnerable system.

Input passed to the "serverPath" parameter 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 reported in version 6.1.5 and prior. Other
versions may also be affected.

SOLUTION:
Set "register_globals" to "Off".

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