An improper access control vulnerability has been discovered in Apache Spark

In all versions of Apache Spark, its standalone resource manager accepts code to execute on a ‘master’ host, that then runs that code on ‘worker’ hosts. The master itself does not, by design, execute user code. A specially-crafted request to the master can, however, cause the master to execute code too. Note that this does not affect standalone clusters with authentication enabled. While the master host typically has less outbound access to other resources than a worker, the execution of code on the master is nevertheless unexpected.

Note: Brocade SANnav versions v2.2.0, v2.2.1 and v2.2.2 contain the affected open source routines, but these routines are not in the execute path accessible to users. While Brocade SANnav is not vulnerable to this CVE, a security update is being provided in SANnav versions v2.2.2a and v2.3.0 to remove the vulnerable component
