The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Test your applicationsThere is no fix version for org.apache.spark:spark-core
. To mitigate the problem, standalone masters, should disable the REST API by setting spark.master.rest.enabled
to false if it is unused, and/or ensure that all network access to the REST API
is restricted to hosts that are trusted to submit jobs. Mesos users can stop the MesosClusterDispatcher
, though that will prevent them from running jobs in cluster mode. Alternatively, they can ensure access to the MesosRestSubmissionServer
is restricted to trusted hosts.
org.apache.spark:spark-core is a fast and general cluster computing system for Big Data.
Affected versions of this package are vulnerable to Insecure Defaults. Apache Spark's standalone master exposes a REST API
for job submission, in addition to the submission mechanism used by spark-submit. In standalone, the config property spark.authenticate.secret
establishes a shared secret for authenticating requests to submit jobs via spark-submit. The REST API
does not use this or any other authentication mechanism, and this is not adequately documented. In this case, a user would be able to run a driver program without authenticating, but not launch executors, using the REST API
.
