What is CVE-2017-7678?
CVE-2017-7678 is a medium-severity cross-site scripting vulnerability in n/a, published on 12 Jul 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-79
