CVE-2018-5490: Netapp Clustered Data Ontap

High severity, CVSS 8.8. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Netapp Clustered Data Ontap: before 8.3 (fixed in 8.3)
