List of CVEs: CVE-2015-1862, CVE-2015-3315
This module attempts to gain root privileges on Linux
systems with a vulnerable version of Automatic Bug Reporting
Tool (ABRT) configured as the crash handler. A race
condition allows local users to change ownership of
arbitrary files (CVE-2015-3315). This module uses a symlink
attack on /var/tmp/abrt/*/maps
to change the ownership of
/etc/passwd
, then adds a new user with UID=0 GID=0 to gain
root privileges. Winning the race could take a few minutes.
This module has been tested successfully on: abrt
2.1.11-12.el7 on RHEL 7.0 x86_64; abrt 2.1.5-1.fc19 on
Fedora Desktop 19 x86_64; abrt 2.2.1-1.fc19 on Fedora
Desktop 19 x86_64; abrt 2.2.2-2.fc20 on Fedora Desktop 20
x86_64; abrt 2.3.0-3.fc21 on Fedora Desktop 21 x86_64.
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 > use exploit/linux/local/abrt_raceabrt_priv_esc
msf exploit(abrt_raceabrt_priv_esc) > show targets
... a list of targets ...
msf exploit(abrt_raceabrt_priv_esc) > set TARGET target-id
msf exploit(abrt_raceabrt_priv_esc) > show options
... show and set options ...
msf exploit(abrt_raceabrt_priv_esc) > set SESSION session-id
msf exploit(abrt_raceabrt_priv_esc) > exploit
Required Options
- SESSION: The session to run this module on.
Knowledge Base
Description
This module attempts to gain root privileges on Linux systems with a vulnerable version of Automatic Bug Reporting Tool (ABRT) configured as the crash handler.
Vulnerable Application
A race condition allows local users to change ownership of arbitrary
files (CVE-2015-3315). This module uses a symlink attack on
/var/tmp/abrt/*/maps
to change the ownership of /etc/passwd
,
then adds a new user with UID=0 GID=0 to gain root privileges.
Winning the race could take a few minutes.
This module has been tested successfully on:
- abrt 2.1.11-12.el7 on RHEL 7.0 x86_64
- abrt 2.1.5-1.fc19 on Fedora Desktop 19 x86_64
- abrt 2.2.1-1.fc19 on Fedora Desktop 19 x86_64
- abrt 2.2.2-2.fc20 on Fedora Desktop 20 x86_64
- abrt 2.3.0-3.fc21 on Fedora Desktop 21 x86_64
Verification Steps
- Start
msfconsole
- Get a session
- Do:
use exploit/linux/local/abrt_raceabrt_priv_esc
- Do:
set SESSION [SESSION]
- Do:
check
- Do:
run
- You should get a new root session
Options
USERNAME
Username for the new UID=0 user (default: random)
SESSION
Which session to use, which can be viewed with sessions
WritableDir
A writable directory file system path. (default: /tmp
)
Scenarios
