CVE-2020-8583
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedElement Software versions prior to 12.2 and HCI versions prior to 1.8P1 are susceptible to a vulnerability which could allow an attacker to discover sensitive information by intercepting its transmission within an https session.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an information disclosure vulnerability in Element Software and HCI where sensitive data transmitted within an HTTPS session can be intercepted by an attacker. The flaw suggests improper TLS/cryptographic implementation or leakage of sensitive data despite the use of HTTPS encryption.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify NetApp Element OS versionAccess the Element OS management interface or run the 'Get-ElementClusterInfo' or 'version' command via SSH to the storage cluster. Look for the Element software version number.Affected if Version is 10.0 or higher but lower than 12.2
-
Identify NetApp HCI versionAccess the HCI management node via web UI or run 'mnode inventory' command. Check the HCI version in the deployment details or through the Element interface.Affected if HCI version is 1.8 or earlier
-
Inspect TLS/SSL configurationReview the TLS settings on the Element OS management interface or in the backend configuration files. Look for weak cipher suites, disabled certificate validation, or misconfigured SSL/TLS settings.Affected if Weak ciphers are enabled or certificate validation is disabled/misconfigured
-
Capture and analyze HTTPS trafficUse a network packet capture tool (like Wireshark or tcpdump) on the management network to capture HTTPS traffic to/from the Element OS or HCI system. Inspect the captured traffic for sensitive data visible in plaintext or for signs of TLS stripping.Affected if Sensitive data such as credentials, tokens, or API keys are visible in plaintext within captured HTTPS sessions
-
Check for TLS downgrade or strippingReview HTTP traffic logs and configuration to see if the system supports HTTP-to-HTTPS redirection or if TLS can be bypassed. Verify that HTTPS is enforced for all sensitive communications.Affected if HTTP is allowed or TLS can be stripped/downgraded for sensitive endpoints
You are affected if running NetApp Element OS versions 10.0 through 12.1 or NetApp HCI version 1.8 or earlier with misconfigured TLS settings that allow sensitive data exposure in HTTPS sessions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data12.2
Upgrade Element Software to version 12.2 or later and HCI to version 1.8P1 or later to remediate the vulnerability.
