CVE-2019-16209
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 · uneditedA vulnerability, in The ReportsTrustManager class of Brocade SANnav versions before v2.0, could allow an attacker to perform a man-in-the-middle attack against Secure Sockets Layer(SSL)connections.
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 · moderate confidenceThis is an SSL/TLS certificate validation vulnerability in Brocade SANnav's ReportsTrustManager class. The improper implementation allows an attacker to intercept SSL connections, potentially enabling man-in-the-middle attacks by not properly validating server certificates.

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 SANnav installation versionLocate the installed Brocade SANnav version through the product's web interface (typically shown in the login page footer or under Help > About), or check the version file on the SANnav server if accessible via CLIAffected if The installed version is any version prior to 2.0 (e.g., 1.x, 1.2.x, 1.3.x, 1.4.x, 1.5.x, 1.6.x, 1.7.x)
-
Confirm Reports module is activeIn the SANnav web interface, navigate to the Reports section or check if the Reports feature has been configured and is accessible to usersAffected if Reports functionality is enabled and in use, as the vulnerability exists in the ReportsTrustManager class
-
Check SSL certificate validation behaviorUse a network capture tool (such as Wireshark) to inspect SSL/TLS traffic when accessing SANnav Reports, or attempt a man-in-the-middle test with an invalid server certificate to observe whether the connection is acceptedAffected if The system accepts SSL connections to the Reports endpoint even when presented with an invalid, expired, or self-signed certificate that should be rejected
-
Review TrustManager configurationIf server-side access is available, examine the Java runtime configuration or application logs for the ReportsTrustManager class implementation and its certificate validation logicAffected if The ReportsTrustManager class lacks proper certificate chain validation, hostname verification, or uses a permissive trust store configuration
You are affected if your Brocade SANnav installation is any version prior to 2.0 and the Reports feature is enabled, as the ReportsTrustManager class does not properly validate SSL/TLS server 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 data2.0
Upgrade to Brocade SANnav version 2.0 or later, which contains the corrected certificate validation logic in the ReportsTrustManager class.
