HIGH: Accessible Hadoop Report



This report identifies hosts that are running Hadoop and have either the NameNode or DataNode web interfaces running and accessible to the world on the Internet.

At a minimum, this can allow for information-gathering against the target organization.

In other instances, it may allow a threat actor to manipulate the Hadoop instance.

Severity levels are described here.

Track exposed Hadoop instances on our Dashboard.
