.htaccess file for vB5x with Exploit patches and Advanced caching.

Recommended Posts

This is an advanced vB5x [URL="http://www.htaccess-guide.com/"].htaccess[/URL] file. (With some modification, it can also be used on all other vB versions.)
This .htaccess file will protect vBulletin 5.x from all currently known [URL="https://vbwarez.net/threads/16930-Fix-for-vb5-1-x-Security-Exploits?highlight=exploit"]exploit attacks[/URL] without the need to alter any PHP or SQL data.
The cache control system is common to Apache servers and reduces page load times by roughly 40% on reload.

It offers -
Apache MOD caching;
Securing all HTAccess and Config files;
Redirecting all HTTP requests to HTTPS;
Enhance image compression and service if DEFLATE is supported;
Browser bug protection;
Advanced cookie control and expiration;
Extensive Header and Font control;
Offsite linking protection;
MIME caching;
PERL exploit defense;
ANSI and Script exploit defense;
Fake User Agent defense.

Note 1: You can not simply copy and paste this code. You must set the [COLOR="#00FF00"]site addresses[/COLOR] to match your own server.

Note 2: vB specific code is now highlighted in [COLOR="#FFA07A"]orange[/COLOR].
Although some of the other code is included in the vB .htaccess file, it is common to most .htaccess files and as such should be included.

Note 3: In order to include more files to be protected from 'hot linking', expand upon this line, [COLOR="#00FFFF"]<FilesMatch "\.(gif|png|swf|jpe?g)$">[/COLOR]
Presently it stops people off site from linking to webpage files, images/photos.
If you want to stop linking to other files, you might try for example-
<FilesMatch "\.(gif|png|swf|jpe?g[COLOR="#00FFFF"]|zip|rar|ace|mp3|mp4|avi[/COLOR])$">

Also, one might want to add ico to the list. Why? Specifically, the favicon.ico file is linked to browsers with bookmarked/favorite sites. Here is the kicker, every time a browser loads a page, it refreshes its favicon.ico files by testing the links, even if not on that website! A small site like this one, with lets say for example 100 users with the site bookmarked, visit an average of 100 other sites per day, THIS site just got hit with 10,000 file hits in one day. For those on metered bandwidth, that can really hurt. In the dialup days it was a site killer. By adding ico to the no-hot-linking code, the ico only loads from this site (and only if the cache needs updating).

Note 4: In order to disable the HTTP to HTTPS routing, locate and remove the code block in [COLOR="#FFFF00"]yellow[/COLOR].

[quote name='windowsguru']nice job Snail you come up with it?[/QUOTE]

Part of it is from the vB5.x installation.
I came up with a lot of it, especially the exploit fixes.
I also obtained many examples from numerous other sources and added them, sorted them, and tested them until it all worked.

This is the one I use on my vB5.1.9 server. Been running for nearly a year under vB5x and it works well.
In reviewing the vB5.2.2 .htaccess file, nothing changed, so the virtual folders and commands are still good.

Ever since people began using the 25 year old exploit attacks on vB's sad code, I have been looking for methods of protecting all forums without the hassle of editing all of their code. The .htaccess file seemed the best method.

It would not take too much to compare a vB 4x .htaccess file and add the new code to it.
In fact, anyone running an Apache server would benefit for much of the code as it will work for all hosting, not only vB.
Simply copy the code over, omitting the vB unique code.
The trick is checking all your code to avoid duplication. While duplication won't cause any crashes, it will use up double the resources and a small amount of additional bandwidth.

I will go back and edit the code to highlight vB specific code.
Okay, the vB specific code is now highlighted in [COLOR="#FFA07A"]orange[/color].
Although some of the other code is included in the vB .htaccess file, it is common to most .htaccess files and as such should be included. Edited by Snail

[quote name='windowsguru']I'm running Apache on my server with IPS 4.1 and would benefit from this as well as long as I change it for IPS.[/QUOTE]

Correct. .htaccess files are not per se' specific to any forum. It just so happens that this one includes code required to run vB5x.
By removing that code block and adding this to your server (and including any IPB specific code) it should work fine.

The one thing that seems to catch people up is that this code is set up to redirect ALL http requests to https.
If you are not running a secure server no pages will be served.
I HIGHLY recommend running on HTTPS these days. It is a tad bit slower and uses additional resources, but it also makes it more difficult for malicious hackers and governments to cause damage.
I will add a new note and highlight the routing code, to be removed for those who wish to remain on HTTP only.

[quote name='windowsguru']I'm running my own home made dedicated server and don't have a clue howto get https going[/QUOTE]

Depending upon what flavor of Apache you are using, Windows/Unix, v1x/v2x, Bare/WAMP/XAMP, et c. your setup will vary slightly.
Fortunately Apache is open source with a LOT of documentation.
The hardest part is in assigning SSL certificates.
I won't get into a how-to here as MANY websites already exist dedicated to instructing the process.
It is simply a matter of security which I recommend. I have highlighted the code block to remove for use on HTTP servers.
