CVE-2020-1675
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 · uneditedWhen Security Assertion Markup Language (SAML) authentication is enabled, Juniper Networks Mist Cloud UI might incorrectly process invalid authentication certificates which could allow a malicious network-based user to access unauthorized data. This issue affects all Juniper Networks Mist Cloud UI versions prior to September 2 2020.
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 confidenceIn the Juniper Mist Cloud UI with SAML authentication enabled, the system incorrectly processes invalid authentication certificates, allowing a malicious network-based attacker to bypass proper certificate validation and gain unauthorized access to data.

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.
-
Verify SAML authentication is enabledLog into the Juniper Mist Cloud UI admin console and navigate to Organization > Settings or Authentication settings. Look for SAML/SSO configuration section and confirm SAML authentication is turned ON.Affected if SAML authentication is enabled - this is a prerequisite for the vulnerability to be exploitable.
-
Determine the Mist Cloud UI version or release dateIn the Mist Cloud UI admin console, check the footer or Help/About section for the software version or release date. Alternatively, check your deployment documentation or contact Juniper Mist support to confirm the specific release version deployed.Affected if The installed version or release date is before September 2, 2020.
-
Review SAML certificate validation settingsIn the Mist Cloud UI under SAML configuration, inspect the certificate validation settings. Look for options related to certificate verification, SSL/TLS validation, or certificate checking in the SAML identity provider (IdP) settings.Affected if Certificate validation is disabled, set to optional, or appears misconfigured in the SAML settings.
You are affected if SAML authentication is enabled AND your Mist Cloud UI version predates the September 2 2020 release, regardless of certificate validation settings, since the flaw is in how the system processes invalid certificates.

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 data2020-09-02
Ensure the Mist Cloud UI is updated to the September 2 2020 release or later. Review SAML configuration settings and verify that proper certificate validation is enforced.
