112.0. "y" by SPRITE::OSMAN () Thu Apr 18 1985 16:05

Here's a hack that seems to be a minor security hole.
I'll illustrate it by a technical riddle:

Q:	Without knowing any passwords on node STAR::, how could you find
	out the logical name definition for SYS$SYSTEM on STAR:: ?

A:
	$ MAIL NL: STAR::SYS$SYSTEM

Try it !

I call it "minor", because I can't think of any mischief one can do merely
by knowing the definition of logical names.

On the other hand, if some logical name happened to point to a world-readable
directory, then perhaps . . .

The command 
	DIR nodename::
will give you the diskname of the DECnert default account.
I use the command as the shortest way I know to see if a
node is reachable.

    I don't think that you have discovered an unitended hole.

    The DECnet account has always been intended as a 'porthole'
    by which folks on the Net can look at a system.  Managing
    the access rights of the DECNET account is a critical bit of
    system management.
