Summary17322: Need different time and count for lock out access for token VS admin user
Description

Since Brute-force attack with tokens to enter survey is possible : https://bugs.limesurvey.org/view.php?id=15239

We use same settings for lock out token and klock out admin.

But

  1. Way of give access is totally different : username+userpass VS random character
  2. Right after access is totally different : whole DB and data with admin, only a single user data with token
Steps To Reproduce

?

Additional Information

token : bot access : 1 seconds after 3 try is the best
admin : 10 minutes is really better

A fix for "Brute-force attack with tokens to enter survey" is already provided and there is a delay when the token is entered incorrectly several times.
Or maybe I misunderstand the fix you want to provide?

We use same time for Admin user and token user. BUT : it's a totally different attack.

yes : there are a Brute force : but it use the same time and try than admin user.

Admin user brute force attack can use

  • "social attack" : birthday, childrens name
  • other powned password for same user
  • password rainbow table

Token user can only be automatic caracters : randomly chooisen

Else : the right give are really more dangerous

  • Admin user : All database of all user of all survey
  • token user : one user information on one survey

The 1st issue is to use the same system for a totally different concept. If you can not understand this : i can not explain more.

I understand this absolutely fine but this sounds like a feature request and not a bug. Please create a PR and I will take it up from there

I'm using 3.x version behind a reverse proxy and behind kubernetes.
The feature is blacklisting the proxy's address. If you're simply using $_SERVER['REMOTE_HOST'] that's not enough.
You should have care of the address $_SERVER['HTTP_X_FORWARDED_FOR'] also.
My blocked IP is the kubernetes service.

Indeed, Denis.

HTTP_X_FORWARDED_FOR can be a comma separated list of IPv4 addresses.
The least forwarded should be on the left.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For

Maybe I can post a patch on this. Do you accept github Pull requests?

More, on this, I would say the IP address can be easily faked with crafted http requests from an attacker. I wouldn't pay so much attention on this.
