SNMP vulnerability

I have received a letter from Virgin to say that my network may have  an SNMP vulnerability.

Details IP [MOD EDIT: REMOVED]

20th April 2021

I have looked at various posts on this site and believe it is down to my new CCTV which sends me emails if there is an alarm on my system.

How do I resolve this, I don't have a clue from reading previous posts. Help.

Regards Paul

Re: SNMP vulnerability

Hi Jon_GS,

Thanks for replying as I said in my initial request I do not understand computers and need very precise instructions to follow.

Initially I could not access the HUB 3 configuration page but I have now managed to get into the HUB 3 and logged in.

I have accessed the security page and port forwarding and there is one rule for port 161, none for port 162 but I can't find how to delete this rule.

There are no port triggering rules for any port.

I checked the firewall settings and all enabled except Block fragmented IP packets, is this correct?

I would liked to have sent some screen shots to show port forwarding and firewall but this does not seem possible.

Hope this gives you more information.

Regards Bouncer

Re: SNMP vulnerability

Hi Bouncer,

 

Sorry to hear this is causing you a bit of trouble - I'll be honest, I had to ask @DJ_Shadow1966 for some advice on this one.

 

What you will need to do, is disable the UPnP which can be found under 'Advanced Settings' on the left. Then you will need to select 'Apply changes'.

 

Once you have disabled it, please reboot the hub and keep the hub switched off for at least 30 seconds.

 

I hope that helps - if you are still stuck anyway just give us a shout and we'll be more than happy to help further.

 

Kind regards,

 

Beth

Re: SNMP vulnerability

Thanks Mike and Beth for you help.

Have followed your instruction and everything appears to still be working.

Will have to see if I get any further SNMP vulnerability messages from Virgin.
