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.
