Detecting MongoDB instances with no authentication enabled


By default, MongoDB instances do not have access control enabled. Users and roles must be manually configured and authentication enabled in order to protect databases in the instance. Therefore, it is very common to find exposed MongoDB databases that require no authentication.

This recipe describes how to use Nmap to list databases in MongoDB.

How to do it...

To list MongoDB databases, enter the following command:

$ nmap -p27017 --script mongodb-databases <target>

The databases will be shown in the script output section:

   PORT      STATE SERVICE 
   27017/tcp open  mongodb 
   |_mongodb-brute: No authentication needed

How it works...

We launch the NSE script mongodb-databases if a MongoDB server is found running on port 27017 (-p 27017 --script mongodb-databases). By default, MongoDB does not have authentication enabled. If the administrators haven't configured users and roles, the databases will be accessible to anyone.
