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 · unedited
If Brocade Fabric OS before Fabric OS 9.2.0 configuration settings are not set to encrypt SNMP passwords, then the SNMP privsecret / authsecret fields can be exposed in plaintext. The plaintext passwords can be exposed in a configupload capture or a supportsave capture if encryption of passwords is not enabled. An attacker can use these passwords to fetch values of the supported OIDs via SNMPv3 queries. There are also a limited number of MIB objects that can be modified.

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 confidence

In Brocade Fabric OS versions before 9.2.0, when SNMP password encryption is not enabled in the configuration settings, the SNMPv3 privsecret and authsecret values are stored and transmitted in plaintext. These plaintext credentials are exposed in configupload or supportsave capture files, allowing attackers to retrieve the passwords and use them for SNMPv3 queries to fetch OID values and modify certain MIB objects.

MitigationEnable SNMP password encryption in Fabric OS configuration settings and upgrade to Fabric OS 9.2.0 or later to remediate this vulnerability.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Fabric OS version
    Run 'version' or 'firmwareShow' command on the fabric switch to retrieve the installed Fabric OS version
    Affected if Version is below 9.2.0 (e.g., 9.1.x, 9.0.x, 8.x, etc.)
  2. Verify SNMPv3 configuration
    Run 'snmpConfig --show v3' to display SNMPv3 settings including authsecret and privsecret parameters
    Affected if SNMPv3 is enabled with authsecret and privsecret values configured (these are the credentials at risk)
  3. Check SNMP password encryption status
    Run 'snmpConfig --show encryption' or inspect the configuration for the password encryption setting
    Affected if SNMP password encryption is disabled or not set (this is the vulnerable condition)
  4. Inspect configupload or supportsave files
    Examine any previously generated configupload or supportsave files for plaintext authsecret and privsecret values
    Affected if Plaintext SNMPv3 passwords are present in these files (confirms active exposure)

You are affected if running Fabric OS below 9.2.0 with SNMPv3 configured and password encryption disabled, as plaintext credentials can be retrieved from config files.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

Upgrade available Upgrade to 9.2.0 or later
Fixed in 9.2.0
Interim mitigation

Enable SNMP password encryption in Fabric OS configuration settings and upgrade to Fabric OS 9.2.0 or later to remediate this vulnerability.

Recommended fix High confidence

Fabric OS 9.2.0 or later

  1. 1. Upgrade Brocade Fabric Operating System to version 9.2.0 or later to receive the security fix.
  2. 2. After upgrade, verify SNMP configuration settings enable password encryption using the CLI command: `snmpconfig --set snmpv3` or via Fabric Web tools.
  3. 3. For existing installations that cannot immediately upgrade, ensure SNMP password encryption is enabled in configuration settings before performing configupload or supportsave operations.
