Doc Text:	[REJECTED CVE] Any host, whether a peer member or not, can use the remote-host command to gain access to the trusted peer group. The remote host can peer probe itself, modify the volume, set up geo-rep to a 3rd party, etc. Network security is not enough. Take, for instance, a storage-as-a-service model where you allow untrusted users to mount volumes. Since they need access to 24007 to retrieve their volume configuration, they can also issue remote-host commands.	Story Points:	---

Joe Julian (joe) reports:

Any host, whether a peer member or not, can use the remote-host command to 
gain access to the trusted peer group.

The remote host can peer probe itself, modify the volume, set up geo-rep to a 
3rd party, etc.

Network security is not enough. Take, for instance, a storage-as-a-service 
model where you allow untrusted users to mount volumes. Since they need access 
to 24007 to retrieve their volume configuration, they can also issue 
remote-host commands.

Comment 3 Kurt Seifried 2015-02-08 23:03:13 UTC

This is by design, the network and hosts used by Gluster must be trusted.
