A vulnerability exists in geoblog version 1 (latest) that allows users to
delete other peoples comments without administration credentials. It works
on blogs too. Users can delete blogs without user credentials.
The reason why is because the listcomments.php and deletecomments.php
files fail to include checks for authenticity.
The following proof of concept is as follows:
www.example.com/blog/admin/listcomment.php?id=16
The ID being the blog ID obtained from the index. Using this we can go
here...
http://www.truegirlonline.net/blog/admin/deletecomment.php?id=16
And delete comments without any admin sosay.
The fix presently would be to add checks for authenticity like the other
files.
if($_SESSION['login'] != "user_valid_and_logged_in") {
header("Location: ../index.php");
}
