What the CVE records say

CVE-2023-45287 — Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels.

Impact

Successful exploitation of this vulnerability could lead to disclosure of sensitive information.

What to do

Check the affected products listed above against the official advisory's affected-versions table — that is where the exact ONTAP 9 release, ONTAP tool, or management product versions are named.
If affected and a fixed release exists, plan the upgrade — see the ONTAP upgrade runbook.
If exploitation is listed as "active", treat remediation as urgent and review exposure (management LIFs, ONTAP S3, SnapMirror endpoints).
