Improper Handling of Export Policy Rules for SMBv2 and SMBv3 Clients Vulnerability in Clustered Data ONTAP 8.3 Release Candidates

circle-check-alt This advisory should be considered the single source of current, up-to-date, authorized and accurate information from NetApp.

Summary

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 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".
