How to Run

Here is how to run the Samba < 2.2.8a / 3.0.0 Multiple Remote Overflows as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Gain a shell remotely plugin family.
On the right side table select Samba < 2.2.8a / 3.0.0 Multiple Remote Overflows plugin ID 11523.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl samba_trans2open_overflow.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a samba_trans2open_overflow.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - samba_trans2open_overflow.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state samba_trans2open_overflow.nasl -t <IP/HOST>

Go back to menu.
