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
In Brocade SANnav, before Brocade SANnav v2.3.0, syslog traffic received clear text. This could allow an unauthenticated, remote attacker to capture sensitive information.

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 SANnav versions before v2.3.0, syslog traffic is transmitted in clear text without encryption. This allows any network attacker with packet capture capabilities to intercept and read sensitive operational data, authentication tokens, and system events being logged.

MitigationUpgrade to Brocade SANnav v2.3.0 or later, which encrypts syslog traffic. Alternatively, if upgrade is not immediately feasible, ensure syslog traffic traverses isolated/trusted network segments to reduce exposure to attackers.

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 installed Brocade SANnav version
    Log into the SANnav management interface and navigate to the About or System Information section to view the current software version. Alternatively, use the SANnav CLI command 'show version' if available.
    Affected if The installed version is below 2.3.0 (e.g., 2.2.x, 2.1.x, etc.)
  2. Verify if syslog export is configured
    Access SANnav's syslog settings through the web interface under Administration > Syslog or through the configuration panel. Check whether any syslog destinations are defined.
    Affected if Syslog destinations are configured and enabled, exposing traffic to the network
  3. Inspect syslog configuration for encryption settings
    In the SANnav syslog configuration panel, look for options related to TLS, SSL, secure transport, or encryption. Determine if the configured syslog transport uses TCP with TLS/SSL or unencrypted UDP/TCP.
    Affected if Syslog is configured without TLS/SSL encryption (using plain UDP or unencrypted TCP)

You are affected if your SANnav version is below 2.3.0 AND you have syslog export enabled with unencrypted transport, exposing sensitive operational data on your network.

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.

dbcve · scoped
Upgrade available Upgrade to 2.3.0 or later
Fixed in 2.3.0
Interim mitigation

Upgrade to Brocade SANnav v2.3.0 or later, which encrypts syslog traffic. Alternatively, if upgrade is not immediately feasible, ensure syslog traffic traverses isolated/trusted network segments to reduce exposure to attackers.

Recommended fix High confidence

Brocade SANnav v2.3.0

  1. 1. Log in to the Brocade SANnav management interface as an administrator
  2. 2. Navigate to the Administration or Settings section
  3. 3. Check the current SANnav version to confirm it is below 2.3.0
  4. 4. Download the SANnav v2.3.0 (or latest available) upgrade package from the Broadcom support portal at support.broadcom.com
  5. 5. Review the upgrade documentation and release notes for any prerequisites
  6. 6. Create a backup of the current SANnav configuration
  7. 7. Follow the documented upgrade procedure to apply the v2.3.0 update
  8. 8. After upgrade, verify syslog is configured to use encrypted transport (TLS/SSL) rather than plaintext
Caveat Review release notes for any configuration or compatibility changes between your current version and v2.3.0
