Re: Exploit of rpc.cmsd

[jhall () IEG COM (John Hall)]

I had both a Solaris V2.5.1 (fully patched as of March 20) and a
Solaris V2.7 (fully patched as of April 10) broken into.  Both had
CDE and were running rpc.cmsd.  I know the breakin was either
due to rpc.cmsd or rpc.rstatd.  Note the breakin occured using
high numbered ports.

In any case, I haven't had any trouble since turning off rpc.rstatd
and rpc.cmsd.
