Description Siddharth Sharma 2018-06-20 14:08:08 UTC
A flaw was found in the way ceph mon handles user requests. Any authenticated ceph user having read access to ceph can delete, and corrupt snapshot images. 

This would require user to have read access and for that user must have key for authentication. It would only affect snapshots and images. So attacker with read access will only be able to corrupt data of snapshot images and rest of the ceph cluster should work as it is. Affect on integrity would be low and availability part can be controlled by mitigation using 'mon_allow_pool_delete = false' in ceph.conf to disable deletion of pools

Comment 1 Siddharth Sharma 2018-06-20 14:08:11 UTC
Mitigation:

Use  mon_allow_pool_delete = false in ceph.conf to disable deletion of pools


~]$ for p in `rados lspools`
do
   ceph osd pool set $p nodelete true
done

caveat: This mitigation does not protect against  attacker from corrupting snapshot images
