Hi,
I see there are updated modules for your Data ontap version, is that what you are looking for?
occore-5.2.1 came with Java Runtime Environment (JRE) 6.0 update 45, which I believe is the vulnerability you mentioned.
OCUM-7mode:

The following upgrades have been performed in 5.2.4 to fix security vulnerabilities in the Core Package:
Apache® HTTP server 2.4.37
Java Runtime Environment (JRE) 8.0 update 181
Jetty 9.4.12
NetApp Management console will be within the OnCommand console, so should be newer version bundled with 5.2.4.
VASA:

For any other component compatibility, use the matrix site, just in case you want to be 100% sure:
