CVE-2018-8024: Apache Spark

Medium severity, CVSS 5.4. EPSS: 5.3% chance of exploitation in the next 30 days.

In Apache Spark 2.1.0 to 2.1.2, 2.2.0 to 2.2.1, and 2.3.0, it's possible for a malicious user to construct a URL pointing to a Spark cluster's UI's job and stage info pages, and if a user can be tricked into accessing the URL, can be used to cause script to execute and expose information from the user's view of the Spark UI. While some browsers like recent versions of Chrome and Safari are able to block this type of attack, current versions of Firefox (and possibly others) do not.

Affected products

• Apache Spark: from 2.1.0, up to and including 2.1.2; from 2.2.0, up to and including 2.2.1; version 2.3.0 only
• Mozilla Firefox: affected versions not specified
