This cache has been archived.

SmooveTalker: Yep. The bulldozers have claimed the cache. It was only about 100' from the safety of the tree protection zone, but it is time for this one to retire.

Geocache Description:

This cache is not located at the published coordinates.

This is a puzzle. You will need to solve the puzzle to obtain the coordinates of the cache.

This puzzle is the first in a potential series of puzzles involving computer security. For each of these puzzles, I will provide a link to a webpage (or other resource) that suffers from a security vulnerability. It will be up to you to exploit that vulnerability to obtain the coordinates of the cache.

In addition to a link to the vulnerable resource, I will provide guidance to you regarding the nature of the vulnerability. It is very important that you do not stray far from the intended attack vector. If you have any doubts, at any time or for any reason, please contact me before proceeding.

The security vulnerability will never be placed on the cache page itself. After you have looked at the information on the cache page, please follow the provided link and direct your efforts on that resource. You should never attempt to discover or exploit security vulnerabilities in geocaching.com or any resource other than the ones provided explicitly for the purposes of these puzzles.

Please contact me if you are ever unsure of the intended attack vector. I will let you know if you are on the right track. This game is intended to be fun and educational, but it is important that we play within the boundaries. You are ultimately responsible for your own actions.

Depending on the response to this puzzle, I will create others in the series. Without further ado, please click on the picture below to link to your first challenge.
