CVE-2018-11770 SUSE CVE security@suse.de SUSE Security Team SUSE CVE-2018-11770 Interim 1 13 2025-02-17T02:46:53Z current 2021-05-30T14:13:49Z 2025-02-17T02:46:53Z cve-database/bin/generate-cvrf-cve.pl 2020-12-27T01:00:00Z CVE-2018-11770 From version 1.3.0 onward, 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. However, 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. This REST API is also used by Mesos, when set up to run in cluster mode (i.e., when also running MesosClusterDispatcher), for job submission. Future versions of Spark will improve documentation on these points, and prohibit setting 'spark.authenticate.secret' when running the REST APIs, to make this clear. Future versions will also disable the REST API by default in the standalone master by changing the default value of 'spark.master.rest.enabled' to 'false'.
