List of CVEs: CVE-2009-4146, CVE-2009-4147
This module exploits a vulnerability in the FreeBSD run-time
link-editor (rtld). The rtld unsetenv()
function fails to
remove LD_*
environment variables if __findenv()
fails.
This can be abused to load arbitrary shared objects using
LD_PRELOAD
, resulting in privileged code execution. This
module has been tested successfully on: FreeBSD 7.2-RELEASE
(amd64); and FreeBSD 8.0-RELEASE (amd64).
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.

msf exploit(rtld_execl_priv_esc) > show targets
... a list of targets ...
msf exploit(rtld_execl_priv_esc) > set TARGET target-id

... show and set options ...
msf exploit(rtld_execl_priv_esc) > set SESSION session-id
msf exploit(rtld_execl_priv_esc) > exploit
Required Options
- SESSION: The session to run this module on.
Knowledge Base
Description
This module exploits a vulnerability in the FreeBSD run-time link-editor (rtld).
The rtld unsetenv()
function fails to remove LD_*
environment variables if __findenv()
fails.
This can be abused to load arbitrary shared objects using
LD_PRELOAD
, resulting in privileged code execution.
Vulnerable Application
This module has been tested successfully on:
- FreeBSD 7.2-RELEASE (amd64)
- FreeBSD 8.0-RELEASE (amd64)
Verification Steps
- Start
msfconsole
- Get a session
use exploit/freebsd/local/rtld_execl_priv_esc
set SESSION <SESSION>
check
run
- You should get a new root session
Options
SESSION
Which session to use, which can be viewed with sessions
