Sun Solaris, OpenSolaris If you've got Solaris with telnet running, you could be in for a big surprise. There is a fairly trivial Solaris telnet 0-day exploit in the wild [.pdf]. "This was posted to Full-Disclosure. Remote root exploit in the Solaris 10/11 telnet daemon. It doesn't require any skill, any exploit knowledge, and can be scripted for mass attacks. Basically if you pass a '-fusername' as an argument to the –l option you get full access to the OS as the user specified. In my example I do it as bin but it worked for regular users, just not for root. This combined with a reliable local privilege escalation exploit would be devastating. Expect mass scanning and possibly the widespread exploitation of this vulnerability."

Ummm no it's not. You have the option of turning it on during install but that is most definately not the same as being on by default.

Only starting with recent revisions. Solaris 10 u1 and previous versions enabled telnet by default.

u2 and previous previous versions. u3 is the first release with the "secure by default" option.
