A nessus scan was ran on our 6500 that has 2 ssl modules and the followig ports showed open. Can these be disabled, are there any vulnerablilities? What are they used for?
2001,2002 and 2003 are used to display debug messages.
The other ports also have a use to display engineering data.
You can't really attack the SSLM on those ports, but you should normally block all traffic going to the SSLM management interfaces except SSH/Telnet.
