### [BK for Mayor of Oak Tree View](http://xs-sniper.com/blog/2007/09/20/bk-for-mayor-of-oak-tree-view/)

I’m excited about ***[Google Docs](http://docs.google.com)***…. although there is NO WAY you could convince me to upload my sensitive documents to a Google Server, I’m still very interested in seeing how Google’s Engineers tackle the security issues with online document sharing. Security for online collaboration tools is TOUGH, every online collaboration tool I’ve ever assessed has had major issues.

 So I made my way to docs.google.com to see what the hype is all about. I found the link for “***[Watch a Video](http://www.youtube.com/watch?v=eRqUE6IHTEA)***” on the login page. I like Google’s videos and this one did not disappoint. About half way through the video (1:60), I saw something that made me put my beer down… a link to a Google Document.

[![Link to Google Doc](http://xs-sniper.com/blog/wp-content/uploads/2007/09/link-to-google-doc.jpg)](http://xs-sniper.com/blog/wp-content/uploads/2007/09/link-to-google-doc.jpg)

Being the curious sort, I entered the ***[link](http://docs.google.com/Doc?id=dgkcctbn_50d5nhbc&invite=d5xj2f8)*** into my browser address bar. I was surprised to see the following document:

[![Oak Tree View](http://xs-sniper.com/blog/wp-content/uploads/2007/09/oaktree-view.thumbnail.jpg)](http://xs-sniper.com/blog/wp-content/uploads/2007/09/oaktree-view.jpg)

Now, being able to view someone else’s document is pretty bad… but this is a demo… maybe they WANT everyone to see this document… that’s understandable. So what happened next REALLY surprised me… I clicked on the “Edit this page” link, entered my creds… and lo and behold… I had full rights to edit/modify the Oak Tree View newsletter!

[![Full Edit Rights](http://xs-sniper.com/blog/wp-content/uploads/2007/09/edit-email-masked.thumbnail.jpg)](http://xs-sniper.com/blog/wp-content/uploads/2007/09/edit-email-masked.jpg)

I was planning on using the Oak Tree View newsletter to launch my campaign for Mayor of Oak Tree View, but I decided against modifying the page, as I’m not interested in pwning Sam’s pretty little newsletter. I’m sure she’s not interested in what I have to say about Oak Tree View….

[![Access Control?](http://xs-sniper.com/blog/wp-content/uploads/2007/09/access-control.jpg)](http://xs-sniper.com/blog/wp-content/uploads/2007/09/access-control.jpg)
