CVE-2018-5490 is a vulnerability of currently unknown severity. 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. EPSS estimates a 0.86% chance of exploitation in the next 30 days.
