I am sorry but I am an extreme newbie at compiling and the like. I recently ran into a problem where I need to compile mod security with DDISABLE_HTACCESS_CONFIG or may find an alternate solution, but I have looked in the mod_Security documentation up and down and cannot find an answer.

I'll explain my dilema, try to keep it short.

I host people on my pc, and in mod_security. You know the sec aduit log? Well in htaccess they can do:

SecAuditEngine On
SecAuditLog "C:\Apache2\www\badfile.php"

Exclamation This is not good. Mad You can inject PHP into the cookies or the GET data and then access the file right in my root directory! Plus people can go around and place sec logs all over the place. Not good........

I do not want to disable htaccess. I like users to be able to add handlers, and deny IPs, use mod rewrite and the like. Plus I tried to encourage some people to use their own sec filters, unfortunately this will be no more but what can be done besides shutting it down from htaccess... I suppose the audit log thing itself can be "removed" from the code but I have no idea how to go about doing this myself. I have been all over the documentation with no solution.

If you do not trust your users (e.g. running in a web hosting environment) then you should never allow them access to ModSecurity. The .htaccess facility is useful for limited administration control decentralisation, keeping ModSecurity configuration with the application code. But it is not meant to be used in situations when the users may want to subvert the configuration. If you are running a hostile environment you should turn off the .htaccess facility completely by custom-compiling ModSecurity with the -DDISABLE_HTACCESS_CONFIG switch.

If anyone could please assit me with a tutorial, or even compile mod security with this I would be very grateful. Or maybe just a solution to the secaduit problem...... I dont know what I can offer in return but I could link your site on my homepage or something when I do the update...

Note: My apache version is the 2.2.x from here.
