[SOLVED]Control webGUI via wget

(1/1)

Hi,

I'm trying to enable/disable a firewall rule via a script on another machine in the LAN here.

Inspired by the docs https://doc.pfsense.org/index.php/Remote_Config_Backup, I have put the following together:


--- Code: ---wget -qO- --keep-session-cookies --save-cookies cookies.txt \
  --no-check-certificate https://192.168.1.1/diag_backup.php \
  | grep "name='__csrf_magic'" | sed 's/.*value="\(.*\)".*/\1/' > csrf.txt
wget -qO- --keep-session-cookies --load-cookies cookies.txt \
  --save-cookies cookies.txt --no-check-certificate \
  --post-data "login=Login&usernamefld=admin&passwordfld=pfsense&__csrf_magic=$(cat csrf.txt)" \
  https://192.168.1.1/firewall_rules.php  | grep "name='__csrf_magic'" \
  | sed 's/.*value="\(.*\)".*/\1/' > csrf2.txt
wget --keep-session-cookies --load-cookies cookies.txt --no-check-certificate \
  --post-data "if=opt1&act=toggle&id=106__csrf_magic=$(head -n 1 csrf2.txt)" \
  https://192.168.1.1/firewall_rules.php
--- End code ---

However, that doesn't quite do the trick, as I'm getting the following in response to the third wget:


--- Code: ---403 Forbidden
2017-12-24 13:58:39 ERROR 403: Forbidden.
--- End code ---

Not sure what the problem is?

The link that works is https://192.168.1.1/firewall_rules.php?if=opt1&act=toggle&id=106

Thanks for any hint!

jimp:
Use the same page in all three requests. Your first command still hits diag_backup.php

highc:
Yes, sorry. That was left over from my various attempts to get it working. Also with firewall_rules.php in the first command, I get error 403.

jimp:
You are also missing a & between the ID and the csrf parameters in the third command.

Plus you'll need to apply changes.

This works:

--- Code: ---wget -qO- --keep-session-cookies --save-cookies cookies.txt \
  --no-check-certificate https://192.168.1.1/firewall_rules.php \
  | grep "name='__csrf_magic'" | sed 's/.*value="\(.*\)".*/\1/' > csrf.txt
wget -qO- --keep-session-cookies --load-cookies cookies.txt \
  --save-cookies cookies.txt --no-check-certificate \
  --post-data "login=Login&usernamefld=admin&passwordfld=pfsense&__csrf_magic=$(cat csrf.txt)" \
  https://192.168.1.1/firewall_rules.php  | grep "name='__csrf_magic'" \
  | sed 's/.*value="\(.*\)".*/\1/' > csrf2.txt
wget -qO- --keep-session-cookies --load-cookies cookies.txt --no-check-certificate \
  --post-data "if=opt1&act=toggle&id=28&__csrf_magic=$(tail -n 1 csrf2.txt)" \
  https://192.168.1.1/firewall_rules.php | grep "name='__csrf_magic'" \
  | sed 's/.*value="\(.*\)".*/\1/' > csrf3.txt
wget -q --keep-session-cookies --load-cookies cookies.txt --no-check-certificate \
  --post-data "apply=Apply%20Changes&__csrf_magic=$(tail -n 1 csrf3.txt)" \
  https://192.168.1.1/firewall_rules.php -O /dev/null

--- End code ---

highc:
Indeed, that works - thank you!

I had thought I'd need to apply changes to the rules by running /etc/rc.filter_configure via ssh, but this is even simpler.
