Synopsis

The remote web server is affected by a remote code execution vulnerability.

Description

The remote web server is affected by a command injection vulnerability in GNU Bash known as Shellshock. The vulnerability is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system.

How to Run

---

Here is how to run the GNU Bash Environment Variable Handling Code Injection (Shellshock) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

1. Click to start a New Scan.
2. Select Advanced Scan.
3. Navigate to the Plugins tab.
4. On the top right corner click to Disable All plugins.
5. On the left side table select CGI abuses plugin family.
6. On the right side table select GNU Bash Environment Variable Handling Code Injection (Shellshock) plugin ID 77829.
7. Specify the target on the Settings tab and click to Save the scan.
8. 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 bash_cve_2014_6271_rce.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a bash_cve_2014_6271_rce.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - bash_cve_2014_6271_rce.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 bash_cve_2014_6271_rce.nasl -t <IP/HOST>

Go back to menu.
