CVE-2019-16204
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 · uneditedBrocade Fabric OS Versions before v7.4.2f, v8.2.2a, v8.1.2j and v8.2.1d could expose external passwords, common secrets or authentication keys used between the switch and an external server.
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 confidenceBrocade Fabric OS versions before v7.4.2f, v8.2.2a, v8.1.2j and v8.2.1d contain a vulnerability that could expose external passwords, secrets, or authentication keys used for communication between the switch and external servers.

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 the installed Fabric OS versionRun the command `version` or `firmwareShow` on the switch CLI to retrieve the current firmware versionAffected if The version displayed is before v7.4.2f, or falls in the ranges v8.1.2 to v8.1.2j, v8.2.1 to v8.2.1d, or v8.2.2 to v8.2.2a
-
Compare version against affected rangesMap your installed version to the following vulnerable ranges: < 7.4.2f; >= 8.1.2 and < 8.1.2j; >= 8.2.1 and < 8.2.1d; >= 8.2.2 and < 8.2.2aAffected if Your version matches any of these ranges
-
Identify external server configurationsReview switch configuration for entries defining external servers such as backup servers, syslog servers, LDAP/AAA authentication servers, or fabric-wide management interfacesAffected if Any external server entries with associated credentials, secrets, or keys exist in the configuration
-
Inspect credential storage mechanismsExamine configuration files or the output of `configShow` for parameters related to remote authentication, backup paths, or API keys used for external communicationAffected if Plaintext or weakly protected passwords, secrets, or authentication keys are visible in the configuration data
You are affected if your Fabric OS version falls within the vulnerable version ranges AND the switch is configured to communicate with external servers using stored credentials or secrets.

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.
