Objet : Port 5357 -- Vista SP1 ???
I have a homemade tripwire type program that alerted me to someone
connecting to port 5357 on my Vista SP1 box.
To my knowledge, I don't think I have this port open.
From a little time on google, it looks like some people are calling
this a potential info leak problem. I'm curious if anyone is going as
far as to manually block the port, and if so, if there are any
negative consequences?
In my opinion, if this is some sort of default vista webserver that
the firewall doesn't touch, it's but a matter of time.....
If I run 'netstat -anb | find "5357"' it doesn't give the owning
process, it says:
"x: Windows Sockets initialization failed: 5
TCP 0.0.0.0:5357 0.0.0.0:0 LISTENING
TCP [::]:5357 [::]:0 LISTENING"
I tried hitting the port on another Vista computer and it looks like
it's some sort of built in webserver????
This is the response:
"C:\>nc 10.10.12.90 5357
?
HTTP/1.1 400 Bad Request

If I try to hit the port with firefox, since it looks like a
webserver, I get this:
"HTTP Error 503. The service is unavailable."
Very different from hitting a port that's blocked.....
I'm curious what everyone else thinks.
