Apache Spark Remote Code Execution Vulnerability (CVE-2020-9480)

Jun 28, 2020 GMT+08:00

I. Overview

Apache Spark has recently released a security report, which disclosed a remote code execution vulnerability (CVE-2020-9480) in Apache Spark 2.4.5 and earlier versions. According to the security report, a standalone resource manager's master may be configured to require authentication 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.

If you are an Apache Spark user, check your system and implement timely security hardening.
