DMA[2005-0818a] - 'Apple OSX dsidentity privilege abuse'

Description:
After roughly one hour of beating on the freshly released OSX 10.4 I found that /usr/sbin/dsidentity
allows any user on the system to add accounts to Directory Services. Passwords can easily be set at
the time of account creation, and the newly created account can be used to login to the OSX gui. Due
to the lack of shell the account is limited in nature, however once you have logged into the gui
accessing a shell is trivial.

To add an account simply use the following command line and then you can now login as RickJames with the
password isapimp.

CrunkJuice:~ kevinfinisterre$ /usr/sbin/dsidentity -a RickJames -s isapimp -v

After logging in as RickJames open Safari and type file:///bin in the address bar. Double click on bash.
Ignore the warning about not being authorized, and then click cancel when asked to close the application.
Voila Now you have a working bash shell as RickJames.

To remove an account from Directory Services use the following.
CrunkJuice:~ kevinfinisterre$ /usr/sbin/dsidentity -r CharlieMurphy -v

If you rally want to piss off someone's Directory Services try the following.
CrunkJuice:~ kevinfinisterre$ /usr/sbin/dsidentity -a `perl -e 'print "A" x 29000'`
(lather, rinse, repeat)

Work Around:
Install 2005-007 update or just rm -rf /usr/sbin/dsidentity
