Apache Spark < 2.4.6 RCE (CVE-2020-9480)

critical Nessus Plugin ID 172445

Language:

Synopsis

The remote host contains a web application that is affected by a remote command execution vulnerability.

Description

In Apache Spark 2.4.5 and earlier, a standalone resource manager's master may be configured to require authentication (spark.authenticate) via a shared secret. When enabled, however, a specially-crafted RPC to the master can succeed in starting an application's resources on the Spark cluster, even without the shared key. This can be leveraged to execute shell commands on the host machine. This does not affect Spark clusters using other resource managers (YARN, Mesos, etc).

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade Apache Spark to 2.4.6, 3.0.0, or later.
