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
Implementation of the Simple Network Management Protocol (SNMP) operating on the Brocade 6547 (FC5022) embedded switch blade, makes internal script calls to system.sh from within the SNMP binary. An authenticated attacker could perform command or parameter injection on SNMP operations that are only enabled on the Brocade 6547 (FC5022) embedded switch. This injection could allow the authenticated attacker to issue commands as Root.

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 confidence

The SNMP implementation on Brocade 6547 (FC5022) embedded switch blades makes internal script calls to system.sh from within the SNMP binary. An authenticated attacker can inject commands or parameters through SNMP operations, achieving arbitrary command execution as root.

MitigationApply vendor-provided firmware patches when available; until then, restrict SNMP access to trusted IPs only, disable unnecessary SNMP operations, and monitor for anomalous SNMP activity.

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. Identify the device model
    Check the switch model via console, CLI (show chassis or show version), or management interface. Look for Brocade 6547 or FC5022 in the hardware inventory.
    Affected if Device is a Brocade 6547 or FC5022 embedded switch blade
  2. Check the Fabric OS version
    Execute 'version' or 'show firmware' via CLI to retrieve the Broadcom Fabric Operating System version. Compare against the affected range of < 8.2.3e1.
    Affected if Fabric OS version is lower than 8.2.3e1
  3. Verify if SNMP is enabled
    Run 'snmpconfig --show' or check SNMP settings via the management interface. Look for SNMPv1/v2c or SNMPv3 status.
    Affected if SNMP is enabled and accessible
  4. Review SNMP community strings and access controls
    Execute 'snmpconfig' to list community strings and access settings. Check if default communities (like public/private) are in use and which IPs are permitted for SNMP access.
    Affected if Default or weak SNMP communities are configured, or SNMP is accessible from untrusted networks
  5. Inspect SNMP MIB structures for anomalies
    Use snmpwalk to query the device and review any custom MIBs or unexpected OID responses that might indicate modified SNMP scripts or configurations.
    Affected if Unexpected OIDs or custom script references appear in SNMP queries

A system is affected if it is a Brocade 6547/FC5022 running Broadcom Fabric OS below version 8.2.3e1 with SNMP enabled and accessible.

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 8.2.3e1 or later
Fixed in 8.2.3e1
Interim mitigation

Apply vendor-provided firmware patches when available; until then, restrict SNMP access to trusted IPs only, disable unnecessary SNMP operations, and monitor for anomalous SNMP activity.

Recommended fix Moderate confidence

Fabric Operating System 8.2.3e1 or later

  1. 1. Identify the current Fabric Operating System version running on the Brocade 6547 (FC5022) embedded switch using 'version' or 'switchnode' command
  2. 2. Navigate to support.broadcom.com and locate the Fabric OS version 8.2.3e1 or later for the FC5022 switch
  3. 3. Download the appropriate firmware upgrade file for your specific hardware model
  4. 4. Follow Broadcom's standard Fabric OS upgrade procedure: typically upload the firmware to the switch using FTP/SCP, then execute 'firmwaredownload' or 'firmwareupgrade' command
  5. 5. Verify the upgrade was successful by checking the new version with 'version' command
  6. 6. Validate that SNMP operations function correctly post-upgrade
