Jonathan Ellis commented on CASSANDRA-9889:
-------------------------------------------
I could be missing something, but I'm not a huge fan of adding config switches
that replicate limited pieces of authz functionality. Isn't this config switch
the equivalent of "don't grant EXECUTE TRUSTED to anyone?"
> Disable scripted UDFs by default

> Key: CASSANDRA-9889
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9889
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Robert Stupp
> Assignee: Robert Stupp
> Priority: Minor
> Fix For: 3.0.0 rc1
>
>
> (Follow-up to CASSANDRA-9402)
> TL;DR this ticket is about to add an other config option to enable scripted
> UDFs.
> Securing Java-UDFs is much easier than scripted UDFs.
> The secure execution of scripted UDFs heavily relies on "how secure" a
> particular script provider implementation is. Nashorn is probably pretty good
> at this - but (as discussed offline with [~iamaleksey]) we are not certain.
> This becomes worse with other JSR-223 providers (which need to be installed
> by the user anyway).
> E.g.:
> {noformat}
> # Enables use of scripted UDFs.
> # Java UDFs are always enabled, if enable_user_defined_functions is true.
> # Enable this option to be able to use UDFs with "language javascript" or any
> custom JSR-223 provider.
> enable_scripted_user_defined_functions: false
> {noformat}
> TBH: I would feel more comfortable to have this one. But we should review
> this along with enable_user_defined_functions for 4.0.
