It’s good to have a variety of Operating Systems in your hacking lab at home, it helps you get familiar with them..as to break things, you have to know how they work first.

So get to know Solaris, they have some pretty neat security related software inside their OS and generally are pretty good when it comes to having a secure architecture with stuff like Trusted Extensions and DTrace.

As they say:

How else to explore and discover for yourself the many innovations and features that Solaris 10 has to offer, than by running Solaris 10 yourself?

So go ahead, grab a copy and start hacking.

To obtain a copy of Solaris 10 Media DVD visit the site below and fill up the form.

Solaris is pwned by a similar vulnerability to one discovered on AIX systems in 1994.

Yes people that’s 13 years ago…and Sun are still vulnerable, as reported by SANS.

The following will give you root on a lot of Solaris systems:

telnet -l "-froot" [hostname]

Cool eh?

The Internet Storm Center is urging system administrators to disable or restrict telnet functionality to contain the zero-day vulnerability, which, according to center, affects only the most recent versions of Solaris and OpenSolaris.

Sun executives talk up secure Solaris at just about every turn. However, some simple tinkering with the OS’s telnet user environment variable can give outsiders free reign with no authentication requirements. No special tools are required to exploit the vulnerability. Sans has long urged against the use of reusable clear-text passwords when administering telnet.

A Sun spokesman says the company has been able to verify the vulnerability and is in the process of testing a fix. He also says that by default telnet is disabled in Solaris 10, and users would have to follow a series of steps to enable it and even more to allow it to administer root privileges. Sun has long recommended Solaris SecureShell as a more secure alternative to telnet.

So disable telnet now, if you haven’t already..Yes I know Sun are still teaching people to use telnet in their classes, which I find kind of sad.

Like someone else said, I doubt any of us would even use telnet on an exposed system…but we have all worked for corporations or seen people that would.
