A flaw was found in RPC request using gfs2_create_req in glusterfs server. An authenticated attacker could use this flaw to create arbitrary files and execute arbitrary code on glusterfs server nodes.

Mitigation

To limit exposure of gluster server nodes :

1. gluster server should be on LAN and not reachable from public networks.
2. Use gluster auth.allow and auth.reject.
3. Use TLS certificates to authenticate gluster clients.

caveat: This does not protect from attacks by authenticated gluster clients.
