Change Log for Mutillidae 2.0.8:

• Added more comments to the code to explain how defenses work
• Added support for the <u></u> tag to the blog. In secure mode Mutillidae will allow this tag but still safely encode output and stop XSS.
• Added JavaScript filtering to prevent single quotes from being entered in blog entries. This give practice bypassing JavaScript "security" and helps the user understand JavaScript cannot provide security.
• Added lots of JS filtering to login.php. Nearly all characters are filtered. Users are encouraged to understand that JavaScript and filtering are useless for security.
• Added autofocus to login.php and add-to-blog.php
• Added more "allowed dangerous HTML tags" to the blog. Until now only the bold HTML tag was supported. Also the output was not HTML5 compliant. For example, if the user entered a bold tag, then a bold tag was output however the bold tag is depreciated. Styles must be used. So Mutillidae allows the user to input a bold tag but will correctly encode this as a sytle upon output. The italic tag is now supported as a dangerous input which is safely output without fear of Cross Site Scripting. These defenses only operate in secure mode of course. In insecure mode, the site allows any input and simply outputs whatever is input without any encoding.
• Changed menu for OWASP A1 - Injection to differentiate between SQL, HTML, and Command Injection. This should make it more clear which pages exhibit vulnerabilities with the specific injecton sub-types. Also added new link for Blind SQL Injection.
• Changed menu for OWASP A2 - Cross Site Scripting to differentiate between XSS coming in via user supplied fields (GET/POST) and values within HTTP Request Headers.
• Added tutorials feature.
• Added SQL Injection Totorial
• Added Cross Site Scripting tutorial
• Added Command Injection tutorial
• Added new feature. Hints can now be at different levels. Each time the user clicks Hints, the level increases by 1 until rolling over.
• Removed the installation instructions from the home page. A new page for instructions is created and linked from the menu.
• Augmented the installation instructions to include running from Samurai, creating a custom ISO, installing to XAMPP, and running in virutal machines.
• Reformatted install instructions and main home page to be compliant with HTML 5

Change Log for Mutillidae 2.0.7:

• Added a new page rene-magritte.php to explore click-jacking. In secure mode, Mutillidae will send the X-FRAME-OPTIONS: DENY header. In modern browsers, this will cause the browser to throw an error rather than allow the page rene-magritte.php to be framed.
• Added a resources link to the main menu. Links are to information or tools that can help with testing Mutillidae.
• Added new class LogHandler to take over logging. Previously logging statements has to be copied to each spot that logging was needed. With the new class, logging requires only one line of code and the logger automatically logs based on the current security level. If in insecure mode, no attempt to stop XSS or SQLi is made. With the new class, many less lines of code are needed and many more places log. With more places logging, there is a much better chance of finding a log exploit and taking advantage (insecure mode). Logging added to pages: add-to-your-blog, dns-lookup, text-file-viewer, source-viewer.php, register.php, redirectandlog.php, and user-info.php
• Added more default users to initial setup to give more targets.

Change Log for Mutillidae 2.0.6:

• Added a new security vulnerability and counteracting secure code. The "business requirements" for the add-new-blog-entry page now require users to be able to enter a bold tag in their blog. In secure mode, Mutillidae allows this functionality while still protecting the users from mallicous injection input.
• A new secret page has been added. There are lots of test scripts that the developers used to hack Mutillidae inside. It will be very hard to guess the name of the file but there are plenty of vulns that will allow users to locate and open the file.

Change Log for Mutillidae 2.0.6:

• Added a new security vulnerability and counteracting secure code. Cookies are unprotected in insecure mode, but in secure mode, the cookies will have the HTTPOnly attribute applied to them. In reality this vulnerability was always in Mutillidae since ignoring the issue opens the vulnerability (the ability for scripts to access the cookie values). The change is acknowleging this issue and adding the defense. Once we get an SSL certificate installed, the next logical step will be to add the "Secure" attribute to cookies in secure mode, but to not add this attribute in insecure mode.
• Added the X-FRAME-OPTIONS: DENY click-jacking defense in secure mode. In insecure mode, the site does nothing and ignores the issue entirely. This defense only works in newer browsers and javascript framebusters are needed to help older browsers.
• Added insecure comments vulnerability and defense. Some developers use HTML or JavaScript comments instead of using the frameworks comments (ASP.NET, Java, PHP, Etc.)
• Rearranged instructions on home page to emphasize the PHP.ini configuration changes that are needed to get rid of errors.
• Rewrote opendb.inc to have error trapping and custom error handling. If there is an error, there will be some diagnistic information available.

Change Log for Mutillidae 2.0.5:

• browser-info.php - Patched a bug which disabled entire page if the whois server is not reachable. Now only that one line will be disabled. Also replaced Windows style file path slashes with Unix style. Either slash will work in Windows but Linux only accepts the Unix style path else throws an error.

Change Log for Mutillidae 2.0.4:

• user-info.php - Added XSS defenses to the output so that users cannot poison their username, password or signature to cause XSS. This only works in secure code.
• register.php - Added XSS defenses to the output so that users cannot poison their username to cause XSS. This only works in secure code.
• header.php - Added link to this changelog. Changed style of upper header to allow more space for logged in user text. In very small screens, the text was overlapping. Also, the size of the mascot image was reduced to give the user more screen space.
• change-log.php - Added new XSS vulnerability for users to try.

Change Log for Mutillidae 2.0.3:

• index.php - Added PHP version detection and altered forms caching defenses and server header information defenses to use header_remove() only if the version of PHP is at 5.3 or above. Made version string variable that contains whatever version string is for Mutillidae plus "nice" output. Samurai is going through a PHP version change to 5.3 right now and XAMPP just went through the same change. This code is meant to bridge users caught between versions.
• header.php - Made version output simpler. header.php only outputs the header string.
• footer.php - Added PHP version to footer output in insecure mode. In secure mode, server version is not shown.

Change Log for Mutillidae 2.0.2 Beta:

Whole site

• Made local relative links without leading dot
