Wrong server nginx config with plesk11.5

[Azurel]

Hello. I have plesk11.5 and found a big security bug in my script because plesk11 do a strange behavior:

[REMOTE_ADDR] => 95.*.*.*
[SERVER_PORT] => 80
[SERVER_ADDR] => 91.*.*.*
[SERVER_NAME] => domain.com
[SERVER_SOFTWARE] => Apache

[REMOTE_ADDR] => 2003:67:4b4b:*
[SERVER_PORT] => 80
[SERVER_ADDR] => 127.0.0.1
[SERVER_NAME] => domain.com
[SERVER_SOFTWARE] => Apache

You can see... visitors with IPv4 get the correct Server-IPv4, BUT visitors with IPv6 get localhost 127.0.0.1
Thats fatal for me. I check in php ($_SERVER['SERVER_ADDR']=='127.0.0.1' for Offline development. Now all IPv6 users get critical outputs since months!

I have take a look and found this in /etc/nginx/plesk.config.d/server.conf

server {
listen 91.*.*.*:80 default_server ;

location / {
proxy_pass http://91.*.*.*:7080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

server {
listen [2a01:*:0:1]:80 default_server ipv6only=on;

location / {
proxy_pass http://127.0.0.1:7080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

Why is this 127.0.0.1 and not "proxy_pass http://91.*.*.*:7080;" or better "proxy_pass http://[2a01:*:0:1]:7080;"!?

I found another thing with this bug => https://talk.plesk.com/threads/how-permission-correctly-in-vhost.328891/#post-769949

How I can set the ipv6 permanently, instead of 127.0.0.1?

I think this problem is addressed in the following KB - http://kb.odin.com/en/122612. Does this solve your issue?

I have report this "bug" to hosteurope and they have make changed for me

wir haben die Änderung in

"/usr/local/psa/admin/conf/templates/custom/nginx.php"

vorgenommen und die Nginx-Konfiguration mit

"plesk sbin nginxmng -d && plesk sbin nginxmng -e"

neu geschrieben.

Die Änderungen sind nun permanent.

Can anybody tell me, that bug is in plesk12 for /etc/nginx/plesk.config.d/server.conf too? (see start posting) Thanks!
