Category:OWASP CSRFGuard Project
Just when developers are starting to run in circles over Cross Site Scripting, the 'sleeping giant' awakes for yet another web-catastrophe. Cross-Site Request Forgery (CSRF) is an attack whereby the victim is tricked into loading information from or submitting information to a web application for which they are currently authenticated. The problem is that the web application has no means of verifying the integrity of the request. The OWASP CSRFGuard Project attempts to address this issue through the use of unique request tokens.

13:35, 13 June 2008 (EDT) OWASP CSRFGuard 2.2 Beta Released!
In my spare time, I had been working on several minor updates to the OWASP CSRFGuard 2.0 release. Several of these updates address bugs that were identified in the previous release. Currently, I am spending a significant amount of time working on internal Aspect Security projects and have not had enough time to complete the release as I had wanted. One particular area that needs work is the inclusion of automated JUnit test cases. Instead of leaving the source lay untouched on my laptop, I've decided to make it available for people to test. Although this release is officially "Beta", it is very stable and developers are encouraged to consider testing and upgrading to the latest version. The reason for this push is that there are a couple of bugs that were never caught in 2.0. More information regarding the updates to 2.2 Beta can be found here.

Replace it with the download above. The WebContent folder contains several JSP files that were used during testing. One file, "tags.jsp", shows how to use the custom JSP tag to insert the token.
