MAJOR SECURITY FLAW IN ROUTERS
This isn't well known by the general public, there's a major security flaw in routers that have UPnP (universal plug and play) enabled.
Ideally UPnP should be turned off. To test your routers visit run the test.

Please take this seriously.

Perhaps it is not such a good idea to run the test.

How do we know the provenance of the information given above ?

That's a fair point. I know it's safe but my word don't mean sh*t.

Best bet then is to login into your routers admin and turn off UPnP. Then you'll know you're safe from this flaw.

I've used GRC Shields Up application to test my routers and port security for a number of years. It is a good site IMHO

Same here - it's a very good site.

But how many people actually change there routers login details? I bet 80 percent of people just leave it alone after being installed by the broadband provider.

Most access is USERNAME - User and PASSWORD as password.!

Steve Gibson is T H E man when it comes to these - and other internet security-related - matters.

Here is the result of my setup when tested by him just now...

Really? I have UPnP turned ON, but my firewall prevents it being accessed from outside my network. Shields UP confirms no response.

I ran the test. Router is safe but I'm nearly out of butter and the microwave needs cleaning.

Yes really, if someone is unhappy running the test and to be sure they are not vulnerable then disabling UPnP is a good idea.

But hey each to their own, I'm only trying to make people aware, if they don't give a f*ck about their networks safety!

So.... as I said, I ran the test, it says everything is OK, but I have UPnP turned ON. Hence my question... really?

I have UPnP turned on like Bri and my system passed the test. And like Bri's system my firewall prevented it being accessed from outside my network. What is the problem with UPnP. And does that not just apply to wireless connections? I thought the routers applied different levels of checks to outside of network (i.e Internet), inside eithernet wired connection, wireless device.
