What is port 8443 for ?


What is port 8443 for ?

With firmware v12.0.13.8, i've noticed a new port in use, 8443/tcp .

My HTTPS is on 443.


The port 8443 accepts weak ciphers, such as SHA1 and is vulnerable to sweet32 (CVE of 2016 ...).


Browsing the URL directly on port 8443, a popup appears (i'm trying admin account). It works.


Then i see this message in red:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data



I have other M4300 with older firmwares, and they do not show this vulnerability, not this 8443 port active.


Exporting config file , it does not mention this port number 8443


What is this for ?

How to remove it ?

The M4300 series switch does host the REST API service using the https protocol on port 8443 afaik. @LaurentMa please.

Is there a resolution to this problem? I'm seeing the same "64-bit block cipher 3DES vulnerable to the SWEET32 attack (CVE-2016-2183)" vulnerability on my M4300 for port 8443.


Can I disable a feature to resolve this?

Hello @NZ74 


i raised again a ticket to Netgear support shortly after seeing newest firmware not fixing any vuln



Netgear support responded me "the fix is being released in March."

I'll try it shortly after being released and will respond back here, hopefully with good news.
