Port 13(daytime protocol),37(time protocol), used to acquire the network time usually is disabled.
The only vulnerabilities that I know is DDoS, but if the person has its firewall configured properly this will not be a problem. And can be detected pretty easy.

But why did you asked this?

Any port that is open on a computer and which the computer is listening for and processing data from it is vulnerable to DDoS. Also google will always be your best friend <3

a bit of googling got me this:
google wrote:
PORT 13 – Information

Port Number: 13
TCP / UDP: TCP
Delivery: Yes
Protocol / Name: daytime
Port Description: Daytime. Returns the time of day in machine language; can return OS version. Provides host time, which can be useful in timing attacks. Also creates a DOS threat when its output is looped echo port (7). Disable this port on all hosts.
Virus / Trojan: No



source = http://www.auditmypc.com/tcp-port-13.asp



I highlighted the key part. In case you still don't understand: this may return the OS version of a computer. something that is very important to a real hacker in the early stages of an attack.
