8.8

CVSS v3.1

Official Description

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.

Technical Analysis

CVE-2018-5490 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
