Summary

Creative Contact Form is a responsive jQuery contact form for the Joomla content-management-system.

OpenVPN comes with example-scripts to update /etc/resolv.conf using "resolvconf" or systemd-resolvconf. I don't use one of them therefore I modified the script so that it simply changes /etc/resolv.conf directly. I placed a variable "IMMUTEABLE" in this script. If IMMUTEABLE is set to 1, this script will change the fileattribute of /etc/resolv.conf to immuteable. In that way it is possible to prevent other programms like dhcp-clients to change /etc/resolv.conf while openvpn is running.

I gave a talk at the BSides 2019 Vienna about PHP Object Injection. Here is the abstract of this talk:
