TL-SG1016DE TCP port 0 open

Model :

Hardware Version :

Firmware Version :

ISP :

I just audited my network and the following error came up:

TCP port 0 is open on the remote host. This is highly suspicious as this TCP port is reserved and should not be used. This might be a backdoor (REx).

So why is port 0 open on the switch? How can I close it?






























Device Description TL-SG1016DE
MAC Address 60:e3:xxxxxxxx
IP Address 10.0.0.182
Subnet Mask 255.255.0.0
Default Gateway 10.0.0.2

I'm using v1.0. So it seems it is fixed in newer models.

Can I expect a firmware update which resolves this issue?

I do not know, In my opinion, you can contact with tp-link. But according to my experience,it is difficult.after all, this is V1.0, the old version.
If this is not critical issue,they will not release firmware.
