Re: Account Lockout after X Attempts - SRR60

scottdrynan · ‎2021-01-25

I cannot find out how to set a login lockout after a certain number of attempts. I have been viewing my log files and they are filled with people trying to log in 20 times at least. Since this is a "Pro" model - I know it is for small business, I would think that there is a way to limit that number.

Regards,

Scott

On a system with just one single username, you don't want to have an account lockout. say you are exposing the administration to the wild Internet, and when under say "investigation" by the bad guys over a longer period - you will never be able to login again.

Of course, a feature as offered by fail2ban lockout of sneaking IP addresses would be required in this product class.

The Netgear team in charge (with mostly consumer background) for the Orbi systems does not like to work and talk to me because I'm nasty and often complain about such issues and limitations. @YeZ another infamous 🙈 🙉 🙊 case.

We already implemented the feature to lock out the account for 10~15 minutes after a few repeated failure of incorrect username/password. The # of failures is a system level number that applies to every account, not configurable on each account level.

This is where some DoS can happen (same on the newer Local UI access on the switches btw.), the bad boys are sneaking admin and random or dictionary password attempts over hours or days, and the effective admin (coming from a different IP address typically) remains locked out virtually forever.

How many different accounts can exist on the subject SRR60/SRS60? One! It's just admin. No other administrative user accounts can be added my friend.

As I said several times before - the lockout must be based on the source IP - IPv4 and IPv6 - address, not on the one and only default username.

Is there a reason why you cannot block by IP?

Because the spec were "enhanced" in a wrong direction probably - to some 1995 consumer product implementations of another router maker devices one might guess?

Or (as another community member mentioned these hours ❤️ ) because Hardware Business School profit ideas have been replaced MIT engineering.

Here is my most recent log. Does not look like you are resonably blocking it. I would post the whole thing but I am limited to 20000 char. I cut out the middle 200 lines or so.

The log is in my opinion incomplete, the login form and intrusion protection along with the log is implemented in the wrong sequence. The input form for the admin password does continue to work, and the log entry is created regardless if it's blocked or not. It's an old old bug, nothing new - same "feature" on other products. Even if you enter the correct password, the same remote login failure would be shown. Several NAS vendors had it the same way round by the way.

What is also missing is the ability to put up firewall rules triggered by such abuse attempts.

Last but not least, you should contact the abuse desk for the ip address block - Whois IP 89.144.47.8 -> abuse@ghostnet.de and report. This could be suspicious activity (certainly not allowed), or there is some process or application up there which does call to an user which had your home Internet connection public IP address assigned before.

Sorry for the confusion. What I posted was towards Cloud-based Insight login, not the local login attempts on the router itself.

We will look into this "Remote Login Failure" case in the local logs you posted. Thank you.

@scottdrynan It seems like you have enabled "Remote Management" in the SRK60 local web GUI. In that page, you should be able to block IP by only allowing a specific computer or an IP range.

Afraid to chime in again - that's an other unreal minimalistic consumer remote management restriction from 1995 (and and years before by the then young ZyXEL in the young Internet times, sorry saying. How many users have a fixed single IP (or a public subnet) from where they want to remote manage a device? How does this fit to the mobile admin who want to do remote management 24*365 from where ever he is, on different devices?

Every average "pro" router for the better SOHO or smaller SMB device needs features like a fully configurable firewall in general, with rules for WAN->[V]LAN[1..4], WAN->Device, [V]LAN[1|2|3|4]<->[V]LAN[1|2|3|4] ... and so on (not a crazy LAN->Internet service block - another 1995 consumer router feature). Decent firewalls allow country-, region-, continent- source based firewalls, especially for exposed services.

Needless to say, optional add-on security like an authentication certificate (by user account) - this requires installing it on the client devices for https or ssh access. But wait. before we need support for certificates on the https and ssh, means local generation of a CSR, the ability to import certificates, or user friendly automated certificates like Let's Encrypt, ....

Welcome to the year 2021 my friend.

Same here - also the cloud login must block by IP and username, not killing the real user if an acount or the cloud authentication system is under attack.

Hi @scottdrynan

This IP was reported 55 times. Confidence of Abuse is 100%

https://www.abuseipdb.com/check/89.144.47.8

IP Abuse Reports for 89.144.47.8:

This IP address has been reported a total of 55 times from 30 distinct sources. 89.144.47.8 was first reported on November 25th 2020, and the most recent report was 1 day ago.

So please disable remote management on Orbi Pro.

Thanks,

Raghu

Understood RaghuHR. BUT that is not a small business solution, that is a consumer solution.

You shoudl be able to autoblock after X occurences from a specific IP for a set peiod of time.

@RaghuHR the design approach of using services like AbuseIPDB.com is.

run a live check on every remote access attempt
allow reporting iP to the service from the logs, from pushed login failure notifications with repetition counters
...

It's not about an "offline" check for investigations.
