CVE-2020-9480: Apache Spark RCE vulnerability in auth-enabled standalone master

Severity: Important Vendor: The Apache Software Foundation Versions Affected: Apache Spark 2.4.5 and earlier 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). Mitigation: Users should update to Spark 2.4.6 or 3.0.0. Where possible, network access to the cluster machines should be restricted to trusted hosts only.
