Re: Gallery <= 1.4.4-pl4 (phpbb_root_path) Remote File Include Vulnerability

Gallery 1.4.4-pl4 and all versions of Gallery 1 more recent than this (I didn't check older versions as they are over 2 years old) are actually not vulnerable to this. The actual code in contrib/phpBB2/ modules.php is: 

   42           $phpbb_root_path = "./";
   43   // connect to phpbb
   44   include_once($phpbb_root_path . 'extension.inc');
   45   include_once($phpbb_root_path . 'common.'.$phpEx);
   46   include_once($phpbb_root_path . 'includes/functions.'.$phpEx);
which defines phpbb_root_path first. Overwriting this through a get parameter would do no good because of line 42, and by default Gallery 1 refuses to install if register_globals is enabled which should prevent the reported problem even if line 42 is not included. 

Source code for reference:

1.4.4-pl4:
