1761 is port used by the Zenworks Desktop Management Agent. just because its open (which its supposed to be) doesnt mean its vulnerable. patches have been released. of course this does not mean the admin is doing his job.

for a hacker to use this of course he would have to have/gain access to the network. but if this is accomplished they can easily have admin rights on the network so of course your very screwed as opposed to just being plain screwed if the perp just gains access to your network and finds the vuln patched.

you can find exploit code here

this will send shell code to a vulnerable machine and run it which will allow you to operate from/on that machine with the privilages granted by the zenworks server to desktop admins. of course you have to have the metasploit framework installed to use it which makes it somewhat useless to someone hacking in and if you can install it on a network machine you probably dont need it but this does show the danger of this vuln and if it can be coded for metasploit it can be easily be coded to run without it.
