CPE [?]: cpe:/a:samba:samba
Synopsis
The remote Samba server is potentially affected by multiple vulnerabilities.
Description
The version of Samba running on the remote host is 4.13.x prior to 4.13.14, 4.14.x prior to 4.14.10, or 4.15.x prior to 4.15.2. It is, therefore, potentially affected by multiple vulnerabilities as referenced in the vendor advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Samba version 4.13.14 / 4.14.10 / 4.15.2 or later.
Public Exploits
Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (GitHub)
Exploit Ease: Exploits (PoCs) are available
Here's the list of publicly known exploits and PoCs for verifying the Samba 4.13.x < 4.13.14 / 4.14.x < 4.14.10 / 4.15.x < 4.15.2 Multiple Vulnerabilities vulnerability:
- GitHub: https://github.com/jirib/notes
[CVE-2020-25717]
Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.
WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.

How to Run
Here is how to run the Samba 4.13.x < 4.13.14 / 4.14.x < 4.14.10 / 4.15.x < 4.15.2 Multiple Vulnerabilities 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 Misc. plugin family.
- On the right side table select Samba 4.13.x < 4.13.14 / 4.14.x < 4.14.10 / 4.15.x < 4.15.2 Multiple Vulnerabilities plugin ID 155620.
- 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_4_15_2.nasl -t <IP/HOST>
