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
Possible information exposure through log file vulnerability where sensitive fields are recorded in the debug-enabled logs when debugging is turned on in Brocade SANnav before 2.3.0 and 2.2.2a

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

In Brocade SANnav versions prior to 2.3.0 and 2.2.2a, when debugging is enabled, sensitive fields are written to debug log files, potentially exposing credentials, tokens, or other confidential data that could be harvested by attackers with access to those logs.

MitigationUpgrade Brocade SANnav to version 2.3.0 or 2.2.2a, or disable debug logging if upgrading is not immediately feasible.

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 SANnav version
    Locate the installed Brocade SANnav version in the application GUI under 'About' or via the command line interface if available. Compare this version number against the affected ranges: versions prior to 2.2.2a or prior to 2.3.0.
    Affected if The installed version is earlier than 2.2.2a or earlier than 2.3.0.
  2. Verify debug logging status
    Access the SANnav administration console and navigate to the logging or diagnostic settings. Check whether debug or verbose logging is currently enabled for any component or module.
    Affected if Debug logging is turned on in the SANnav configuration.
  3. Locate debug log files
    Browse the SANnav installation directory and standard log locations for files with 'debug' in the name or with the .log extension that were created during debugging sessions.
    Affected if Debug log files exist on the system.
  4. Inspect logs for sensitive data
    Open the debug log files using a text editor or grep command and search for patterns that may indicate exposed credentials, passwords, tokens, API keys, or other confidential fields.
    Affected if Debug logs contain plain-text credentials, tokens, or other sensitive information.

A user is affected if their SANnav version is prior to 2.3.0 or 2.2.2a AND debug logging is enabled, resulting in sensitive data being written to accessible log files.

Upgrade available Upgrade to 2.2.2a or later
Fixed in 2.2.2a
Interim mitigation

Upgrade Brocade SANnav to version 2.3.0 or 2.2.2a, or disable debug logging if upgrading is not immediately feasible.

Recommended fix Moderate confidence

SANnav version 2.2.2a or later (latest stable release)

  1. 1. Identify the current Brocade SANnav version by navigating to the SANnav web interface and checking the 'About' section or using the SANnav management console.
  2. 2. If the current version is earlier than 2.2.2a, download the latest SANnav version 2.2.2a or later from the Broadcom support portal at support.broadcom.com.
  3. 3. Review the SANnav upgrade documentation and release notes for version 2.2.2a to understand upgrade prerequisites and procedures.
  4. 4. Create a full backup of the current SANnav configuration and database before initiating the upgrade.
  5. 5. Follow the documented upgrade procedure to upgrade to SANnav version 2.2.2a or the latest stable release.
  6. 6. After upgrade completion, verify the new version is installed by checking the 'About' section in the SANnav interface.
  7. 7. Ensure debugging is only enabled when necessary and review log configurations to prevent sensitive information exposure.
Caveat Review release notes for any configuration or feature changes between current version and 2.2.2a; test upgrade in non-production environment first
