CVE-2018-8024 Apache Spark XSS vulnerability in UI

Severity: Medium

Vendor: The Apache Software Foundation

Versions Affected:
Spark versions through 2.1.2
Spark 2.2.0 through 2.2.1
Spark 2.3.0

Description:
In Apache Spark up to and including 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.

Mitigation:
1.x, 2.0.x, and 2.1.x users should upgrade to 2.1.3 or newer
2.2.x users should upgrade to 2.2.2 or newer
2.3.x users should upgrade to 2.3.1 or newer
