Official Description
NetApp Clustered Data ONTAP 8.3.x before 8.3.2P12 allows remote authenticated users to execute arbitrary code on the storage controller via unspecified vectors.
Technical Analysis
CVE-2017-12421 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.
