[solved] hddtemp shows open port???

orphius1970 · 2010-01-11 01:45:48

i just ran nmap to test my ports and I get this:

PORT STATE SERVICE VERSION
7634/tcp open hddtemp hddtemp hard drive info server

Is there a way to block this or do I need to worry about it?

Hi rphius1970,

if hddtemp is only listening on localhost, than I would say there is nothing to worry about.

On my system:

# netstat -plnt | grep hddtemp
tcp        0      0 127.0.0.1:7634          0.0.0.0:*               LISTEN      1923/hddtemp

Did you start nmap on the machine that is running hddtemp or did you scan for open ports from a different pc?

If "hddtemp" has root's privileges, then there is a risk of privilege escalation. Surely "hddtemp" does not require a password from incoming connections. A model of attack is as follows: a malicious process on a local machine connects to "hddtemp", using vulnerability in "hddtemp" it gets root's privileges.

set the PARAMS in /etc/conf.d/hddtemp so it only listen to localhost.

PARAMS="-q -l 127.0.0.1"

Andrwe,
I did exactly as you say. scan from my own puter shows the open port, but not from an external scan.
Thankyou!
