To me that rule is too open ended also and liable to exploit.
I don't know what you mean by an open port, no restriction on use, rather than what something like grc.com shields up would call an open port, one that isn't stealthed. A port that isn't stealthed can effectively announce your presence when port scanned, leaving you liable to more detailed scanning.
What if you allowed access based on uTorrent, program permissions rather than a global rule like this. Perhaps you need to visit a comodo forum.
