For the last few years, we have been using subversion to manage our source code and move code live. One thing we overlooked was the fact that the .svn directories were exposed on our web server. Thanks to Ehraz and Umraz Ahmed ( #securityexe and #umrazahmed on twitter) for reporting this problem to us.

As a solution, we made a couple of configuration changes:

- prevented access to the directories via a "<Directory>" directive,
- added respective rules to our web application firewall.

For the last couple of months DRG (the Dragon Research Group) has posted some interesting security challenges. The last one, for December, is currently online so if you want to test your security skills – and post the solutions for the public benefit, do not miss the current challenge available at
Those of you who like playing CTFs will enjoy this. Other (older) challenges are still online too, so if you have some time off here’s a nice way to spend those cold nights (or warm – depending where in the world you are).
… and remember, the devil is in the details ;-)
