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.

Security readout for executives and security teams

CVE-2017-7678 is a client-side issue in Apache Spark web UIs before 2.2.0. An attacker could trick a trusted user into opening a crafted link tied to a shared Spark cluster, causing content to be reflected in Spark UI pages and potentially run on MS Windows-based clients. Exposure is most likely in organizations still running Apache Spark before 2.2.0, especially shared clusters where users access master or history server web UIs from Windows clients. Treat this as a targeted hygiene issue, not an emergency from the supplied evidence. Prioritize remediation where legacy shared Spark clusters are still used by Windows-based analysts or engineers. Mitigation focus: Upgrade Apache Spark deployments to version 2.2.0 or later.; Restrict Spark master and history server web UI access to trusted networks and users.; Review Apache Spark advisory guidance for any environment-specific remediation notes..
