Background

Apache Spark is an open-source distributed computing system used for big data processing and analytics. The spark-core package is a fundamental component of Apache Spark, providing the core functionality and APIs for Spark applications. This vulnerability affects the spark-core_2.10 and spark-core_2.11 versions of the package.

Vulnerability Detail

The vulnerability in Apache Spark allows an attacker to exploit a user's trust in the server by tricking them into visiting a link that points to a shared Spark cluster. The attacker can submit data, including MHTML, to the Spark master or history server. This data, which may contain a script, is then reflected back to the user and can be executed by MS Windows-based clients. It is important to note that this is not an attack on Spark itself, but rather on the user who may inadvertently execute the script when viewing elements of the Spark web UIs.

How To Fix
