CVE-2017-7678 Information

Description

In Apache Spark before 2.2.0 it is possible for an attacker to take advantage of a user’s trust in the server to trick them into visiting a link that points to a shared Spark cluster and submits data including MHTML to the Spark master or history server. This data which could contain a script would then be reflected back to the user and could be evaluated and executed by MS Windows-based clients. It is not an attack on Spark itself but on the user who may then execute the script inadvertently when viewing elements of the Spark web UIs.
