- Solaris 2.5 x86 aspppd (semi-exploitable-hole)
-
- Although initialy when I first saw this hole I thought "noone is realy
- vunerable", but after seeing how badly aspppd handled my modem line
- getting dropped (Solaris doesnt down the interface, so you have to either
- restart aspppd, or do it manualy), I figured some people running scripts
- that restart aspppd might be.
-
- Its relatively simple, in /tmp/ lies .asppp.fifo which is world r/w if
- aspppd isnt running you simply ln -s /.rhosts /tmp/.asppp.fifo, when root
- executes aspppd, /.rhosts is opened r/w as a fifo, the second aspppd dies
- /.rhosts becomes a normal file world r/w.
-
- aspppd isnt setuid, so it must be run by root and later killed for any of
- this to work. Not likely, but if your like me and have a small script to
- keep up your link, (not anymore) your probably vunerable.
