PHP Session File Hacks

Thursday, June 24th, 2010

What they say about kung-fu is true..

It can be attained by anyone through hard work over time. You can become as good as the amount of work you put in. Here’s a short look at a basic technique that I use. Simply reverse engineering the source code and taking notes along the way…

static void php_session_send_cookie(TSRMLS_D)
  if (SG(headers_sent)) {
          if (output_start_filename) {
                  php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot send session cookie - headers already sent by (output started at %s:%d)",
                          output_start_filename, output_start_lineno);
          } else {
                  php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot send session cookie - headers already sent");
          }
          return;
  }
 
  /* URL encode session_name and id because they might be user supplied */
  e_session_name = php_url_encode(PS(session_name), strlen(PS(session_name)), NULL);

Advanced WordPress wp-config.php Tweaks

Wednesday, March 3rd, 2010

The bottom line for this article is that I want to make WordPress as fast, secure, and easy to install, run, and manage because I am using it more and more for client production sites, I will work for days in order to solve an issue so that I never have to spend time on that issue again. Time is money in this industry and that is ultimately (time) what there is to gain by tweaking WordPress.

Note: I spent no time on readability, this is primarily a read the code and figure it out article.. This is for advanced users looking for a reference or discussion and for those of you looking to advance. Feedback would be great if you make it that far..

Custom bash_profile for Advanced Shell Users

Monday, November 23rd, 2009

Looking for some advanced uses for the shell? Here is ~~some of~~ my best. The shell is where 70% of my work takes place, and I have at least one terminal open almost 100% of the time, for viewing tailing color-coded logs, and of course for the SSH Tunnels that I use to route various networking through, like my email. So I decided that to standardize and create a bash_profile containing the most time-saving and helpful functions that I could use on all the various hosting environments would really be some sweet sugar, so here is my constant Work-in-progress.

It works for all shells I encounter, including BackTrack, Debian, Knoppix, Arch Linux, etc. Also works for many hosting environments I use including DreamHost, HostGator, WiredTree, and pretty much any linux VPS.

I also rely on this heavily from within shell scripts I write to access all the functions and stuff in this .bash_profile, and to do that I just do like:

#!/bin/bash
 
source ~/.bash_profile &>/dev/nulll
 
pm "PM is a function to output nice messages with color"
yn "Are you enjoying the shell" && pm "Thats great!" || pm "Perhaps you're better suited for DOS"
yn "Show Calendar" && aa_calendar
yn "Show Fortune" && aa_fortune

Firefox Add-ons for Web Developers

Sunday, October 18th, 2009

Advanced Web Development by AskApache is a Firefox Collection I created since I’m always trying new Addons out and using multiple computers and I wanted a quick and easy way to install my favorite’s and keep a running list. Firebug, YSlow, LastPass, and Web Developer are the only ones I always use regularly.

I like the idea of the last.fm but it’s not as powerful as the site, which is awesome. Lately listening to Kings of Leon Radio…

Protecting Files with Advanced Mod_Rewrite Anti-Hotlinking

Wednesday, September 16th, 2009

If you have files on your site that you don’t want indexed by malicious search engines, grabbed and leeched by malicious spammers, or stolen and made available elsewhere, you can use mod_rewrite to drastically reduce or totally reduce that activity.

mod_rewrite Fix for Caching Updated Files

Sunday, August 30th, 2009

Web Developers sometimes use file.ext?v=004 as a version control system to force visitors to use updated files. This is terrible. Instead link to apache-003.css and set it to be cached forever. When you change the file you just change the links to apache-004.css. That eliminates millions of bandwidth and resource robbing If-Modified-Since requests. You only need Apache with mod_rewrite, and 1-10 minutes!

An AskApache Plugin Upgrade to Rule them All

Wednesday, July 29th, 2009

So my blog as been rather quiet for almost a year now, and very few updates if any have been released for my Password Protection PLugin, my Google 404 Plugin, and definately not for my AskApache CrazyCache plugin, which I will be releasing last… So for all of you who’ve helped me out by sending me suggestions and notifying me of errors and sticking with it… Just wanted to say sorry about that, and thanks for all the great ideas.. Well, I’ve been sticking with it as well believe it our not. I manage to get free days once in a while, and then its time to jam.

AskApache Debug Viewer Plugin for WordPress

Sunday, April 5th, 2009

The story behind this plugin is sorta wack, but in a good way :). While doing tons of security research on permissions, authorization, access, etc.. for the Password Protection plugin (still being worked on), I needed to have unheard of debugging capabilities while working on the plugin on the various websites, webhosts, and test servers that I use to test in different environments. So I hacked together a bunch of php code that helped me debug, actually I pretty much went overkill and tried to get as much debugging info as programmatically possible, and it ended up being so much code that I took it out of my Password Protection code and made it its own plugin.

Advanced Htaccess Demo/Example using Cookies, Headers, Rewrites

Tuesday, March 31st, 2009

Whoa pretty sweet huh? Bet you’ve never seen that before! As I explain the htaccess code that achieves this, keep in mind this is merely one simple application for this code. It’s much more advanced than your basic htaccess trick, notice how this htaccess acts like a php script, very unusual.. I really wanted to share this trick after I created it for one of my clients because this is the tip of the iceberg. Another use would be to display an alternate style sheet depending on a users theme preference. The coolest thing about this example IMHO is that it uses multiple advanced .htaccess ideas in order for it to work, most htaccess code on the net is very singular. This code uses mod_headers to set the Content-Disposition header for forcing a download and uses mod_rewrite to do the rest.

The Ultimate Htaccess

Saturday, January 10th, 2009

Skip this – still under edit

I discovered these tips and tricks mostly while working as a network security penetration specialist hired to find security holes in web hosting environments. Shared hosting is the most common and cheapest form of web-hosting where multiple customers are placed on a single machine and “share” the resources (CPU/RAM/SPACE). The machines are configured to basically ONLY do HTTP and FTP. No shells or any interactive logins, no ssh, just FTP access. That is when I started examining htaccess files in great detail and learned about the incredible untapped power of htaccess. For 99% of the worlds best Apache admins, they don’t use .htaccess much, if AT ALL. It’s much easier, safer, and faster to configure Apache using the httpd.conf file instead. However, this file is almost never readable on shared-hosts, and I’ve never seen it writable. So the only avenue left for those on shared-hosting was and is the .htaccess file, and holy freaking fiber-optics.. it’s almost as powerful as httpd.conf itself!

Most all .htaccess code works in the httpd.conf file, but not all httpd.conf code works in .htaccess files, around 50%. So all the best Apache admins and programmers never used .htaccess files. There was no incentive for those with access to httpd.conf to use htaccess, and the gap grew. It’s common to see “computer gurus” on forums and mailing lists rail against all uses and users of .htaccess files, smugly announcing the well known problems with .htaccess files compared with httpd.conf – I wonder if these “gurus” know the history of the htaccess file, like it’s use in the earliest versions of the HTTP Server- NCSA’s HTTPd, which BTW, became known as Apache HTTP. So you could easily say that htaccess files predates Apache itself.

Once I discovered what .htaccess files could do towards helping me enumerate and exploit security vulnerabilities even on big shared-hosts I focused all my research into .htaccess files, meaning I was reading the venerable Apache HTTP Source code 24/7! I compiled every released version of the Apache Web Server, ever, even NCSA’s, and focused on enumerating the most powerful htaccess directives. Good times! Because my focus was on protocol/file/network vulnerabilites instead of web dev I built up a nice toolbox of htaccess tricks to do unusual things. When I switched over to webdev in 2005 I started using htaccess for websites, not research. I documented most of my favorites and rewrote the htaccess guide for webdevelopers. After some great encouragement on various forums and nets I decided to start a blog to share my work with everyone, AskApache.com was registered, I published my guide, and it was quickly plagiarized and scraped all over the net. Information is freedom, and freedom is information, so this blog has the least restrictive copyright for you. Feel free to modify, copy, republish, sell, or use anything on this site ;)

Advanced .htaccess Tricks for Securing Sites

Friday, December 19th, 2008

This is all new, experimental, and very very cool. It literally uses .htaccess techniques to create several virtual “locked gates” that require a specific key to unlock, in a specific order that cannot be bypassed. It uses whitelisting .htaccess tricks to specify exactly what is allowed, instead of trying to specify everything that isn’t allowed. Also, by setting specific cookies/tokens after successfully passing through a gate, we can then require the exact cookie/token from the previous gate, which stops an attacker from skipping or bypassing gates.

.htaccess Plugin Blocks Spam, Hackers, and Password Protects Blog

Saturday, November 22nd, 2008

Well what can I say, other than this is sooo DOPE! Here is a list of the modules this plugin (version 4.7 unreleased) will automatically detect. I compiled the list myself using every module included with any default Apache installation for ALL the versions listed below, 1.3 to 2.2+

Want to know something else I’m including in this plugin? For each and every module that is detected, this plugin can then detect ALL of the modules .htaccess Directives! For instance, RewriteRule, AccessFileName, AddHandler, etc.. are each a directive belonging to a module that is allowed to be used from within .htaccess files.

Talk about sick.. these tricks have the diamond disease!
