blueman set_dhcp_handler D-Bus Privilege Escalation

Description

This module attempts to gain root privileges by exploiting a Python code injection vulnerability in blueman versions prior to 2.0.3. The `org.blueman.Mechanism.EnableNetwork` D-Bus interface exposes the `set_dhcp_handler` function which uses user input in a call to `eval`, without sanitization, resulting in arbitrary code execution as root. This module has been tested successfully with blueman version 1.23 on Debian 8 Jessie (x64).

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
