Shai Erera commented on SOLR-6736:
----------------------------------

bq. I'm tempted to just restrict this to support just upload of a configset 
because we have not yet assessed the security implications of these and the 
implications of changing config of a running collection

[~noble.paul], I've read the discussion on SOLR-5287 and was wondering if you 
can explain why limiting this API to only uploading a configset addresses any 
of the security vulnerabilities? The configset may include anything that I 
want, including XSLT files which may be able to hamper the system, correct?

Is it only because we cannot associate a configset with a collection when we 
issue a {{/collections?action=CREATE}} command that you consider it safe? I.e. 
the configset will exist in ZK, but not really used? If so, why enabling this 
at all?

> Managing Solr configuration files on zookeeper becomes cumbersome while using 
> solr in cloud mode, especially while trying out changes in the 
> configurations. 
> It will be great if there is a request handler that can provide an API to 
> manage the configurations similar to the collections handler that would allow 
> actions like uploading new configurations, linking them to a collection, 
> deleting configurations, etc.
> example : 
> {code}
> #use the following command to upload a new configset called mynewconf. This 
> will fail if there is alredy a conf called 'mynewconf'. The file could be a 
> jar , zip or a tar file which contains all the files for the this conf.
> curl -X POST -H 'Content-Type: application/octet-stream' --data-binary 
> @testconf.zip 
> http://localhost:8983/solr/admin/configs/mynewconf?sig=<the-signature>
> {code}
> A GET to http://localhost:8983/solr/admin/configs will give a list of configs 
> available
> A GET to http://localhost:8983/solr/admin/configs/mynewconf would give the 
> list of files in mynewconf
