[ 1. What is this?
This is very nice CMS, You should try it! ;)

[ 2. What is the type of vulnerability?

When admin add 'the same content' twicely, then he will see an error similar to this:
"Duplicate entry 'c9ujq(...)63rscpi5' for key 'PRIMARY' SQL=INSERT INTO `qcd3p_session` (`session_id`, `client_id`, `time`) VALUES ('c9u(...)i5', 1, '1338(...)88')"

So now 'attacker' can find out what is the prefix of Your Joomla installation.
In other way, this bug is available only from admin. ;)

[ 3. Where is bug :)
http://joomla/administrator/index.php?option=com_installer&view=update&task=%2bunion%2bselect%2bnull--.ajax

* Why 'with friends' - because I added to my localhost Joomla installation so
many extensions (to tests;)), so vulnerable could be else part of CMS too (for example:
similar bug I found in latest VirtueMart 2.0.2. Check out at my blog. *
