What is CVE-2018-8024?
CVE-2018-8024 is a medium-severity cross-site scripting vulnerability in Mozilla Firefox, published on 12 Jul 2018. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-200
