Updating wp-ban to include bad URLs

Posted: Sunday, September 6th, 2009 at 12:52 amUpdated: Friday, September 11th, 2009 at 8:20 am

I’ve posted _PHPLIB[libdir] Cross Site Scripting Exploit Explained a while back. Now I’m getting tired of these bozos trying to hack my system in vain, wasting my bandwith and driving up fake page views on my StatPress. So I decided to patch wp-ban to include what I considered bad URLs.

Since I’ll be using wp-ban, it should go without saying that you need WordPress. The changes that I made was for wp-ban 1.50, the current version at the time of this writing.

So first, install wp-ban 1.50 by following this direction. My recommendation is for you to have wp-ban configured, up and running first.

Updating wp-ban to include bad URL ban

The easy way

I’ve made a patch file that you can directly apply to your existing wp-ban folder. Here’s the step:

  1. Make sure you have wp-ban 1.50. If you have something lower, please upgrade to wp-ban 1.50 first. If yours is higher, you can try the manual way on page 2 or leave me a note as I’ll need to update the patch to work on version > 1.50.
  2. Backup BACKUP BACKUP your existing wp-ban directory.
    user@www:~/wp-content/plugins$ cp -R wp-ban wp-ban.bak
    
  3. Before we apply the patch, let’s disable wp-ban. On wp-admin, navigate to Plugins -> Installed. Click on deactivate link on wp-ban.
  4. Download wp-ban bad URL patch file. Save it under wp-content/plugins/wp-ban directory.
  5. OPTIONAL. If your system doesn’t have patch program yet, do install it by running the command below (on Debian based systems)
    user@www:~$ sudo apt-get install patch
    
  6. Patch your existing wp-ban installation to have bad URL functionality.
    user@www:~/wp-content/plugins/wp-ban$ sudo patch -p1 -i \
    > wp-ban.1.50.bad-urls.patch
    patching file ban-options.php
    patching file wp-ban.php
    
  7. Reactivate wp-ban
  8. On wp-admin navigate to Settings -> Ban. You should see all your previous settings plus one new row for settings of bad URLs.
  9. My recommendation is to add the following 3 lines on Banned Ban URLs section.
    • includedir=http://
    • _SERVER[DOCUMENT_ROOT]=http://
    • _PHPLIB[libdir]=http://
    • _phplib%5Blibdir%5D=http://
    • WN_BASEDIR=http://
    • _server[document_root]=http://

    If you find any other URL patterns worth mentioning, please do me a favor and add them on the comments field. Thank you.

  10. Test your newly pimped out wp-ban. If it doesn’t work, restore the backup. (You DID make a backup, didn’t you?)

If for some reasons the easy way doesn’t work for you or you have wp-ban other than version 1.50, go on to the next page. We’ll have to do it the hard way.

    AWESOME!! Thanks for the work. I\’ve been getting nailed by some Koreans constantly trying the SERVER[DOCUMENT_ROOT] over and over again. Even though I\’ve banned them by IP, WP-Ban isn\’t banning them. Hopefully this will take care of them. If not, I\’ll just have to htaccess them.
