What the CVE records say

CVE-2018-5490 — Read-Only export policy rules are not correctly enforced in Clustered Data ONTAP 8.3 Release Candidate versions and therefore may allow more than "read-only" access from authenticated SMBv2 and SMBv3 clients. This behavior has been resolved in the GA release. Customers running prior release candidates (RCs) are requested to update their systems to the NetApp Data ONTAP 8.3 GA release.

Impact

This vulnerability allows write access to “read-only" CIFS data from authenticated SMBv2 and SMBv3 clients which could result in the deletion or manipulation of data that is intended to be "read-only".
