Just a general warning that there are some nasty security issues with Joomla 1.5. In particular, it's possible to reset the admin password with no special attack code!!
Here's the notification from WHT:

I'm sure there are others but this one seemed particularly nasty to me!
Here's a working and tested mod_security 1.x pattern for this and one other issue:
Code:
# Joomla 1.5 null token password reset exploit - RM/BC 20 Aug 08
SecFilterSelective ARG_task "confirmreset" chain
SecFilterSelective POST_PAYLOAD "token=('|%27)"
# Joomla 1.5 SQL injection - 20 Aug 08
# nb: need case independence, on by default in 1.x!
SecFilterSelective ARGS_VALUES ";.*declare%20.*exec"
The patterns may be a little general, comments appreciated!
ps: there are exploits in the wild for this one!
