Impact

Vantage6 currently provides an initial user with username root and password root. This is not ideal for the following reasons:
  • Attackers know that almost all vantage6 servers have a user with username root that probably has admin rights
  • The initial password is very weak and it is possible that administrators forget to reset it.

Patches

No

Workarounds

It is possible to delete the root user after it has been used to create other users

References

We could consider doing this like [mongodb](https://hub.docker.com/ /mongo)

Additional info

Luis uses the following patch to mitigate it:
