CVE-2024-29951
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 SANnav before v2.3.1 and v2.3.0a uses the SHA-1 hash in internal SSH ports that are not open to remote connection.
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 confidenceBrocade SANnav versions prior to 2.3.1 and 2.3.0a utilize the cryptographically weak SHA-1 hashing algorithm for internal SSH port communications. Since these SSH ports are not exposed to remote connections, the attack vector is limited to internal network adversaries who could potentially exploit SHA-1's known collision vulnerabilities.

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 if Brocade SANnav is installedCheck for SANnav installation directory (typically /opt/brocade/sannav or C:\Program Files\Brocade\SANnav) or look for the sannav service in your system's service listAffected if SANnav is installed and running on the system
-
Determine the installed SANnav versionRun 'sannav --version' from the installation bin directory, or check the version file typically located at <install_dir>/sannav/app/version.properties, or access the SANnav web UI and check About/Version informationAffected if The installed version is lower than 2.3.0a (such as 2.2.x, 2.1.x, or earlier releases)
-
Confirm SANnav services are runningCheck if the SANnav internal services are active by querying running processes (look for java or sannav-related processes) or by checking if the management interface is accessible internallyAffected if SANnav services are running and internal SSH communications are active
A system is affected if Brocade SANnav is installed with a version prior to 2.3.0a and the SANnav services are running, enabling internal SSH communications that use the weak SHA-1 hashing algorithm.

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 · scoped2.3.0a
Upgrade Brocade SANnav to version 2.3.1 or 2.3.0a to remediate the weak SHA-1 hashing in internal SSH ports.
SANnav v2.3.1 or later
- 1. Back up the current SANnav configuration and database
- 2. Download the SANnav v2.3.1 or later installer from Broadcom support portal (support.broadcom.com)
- 3. Stop all SANnav services using the management interface or CLI
- 4. Install the SANnav v2.3.1+ upgrade following the standard upgrade procedure
- 5. Verify the SSH configuration no longer uses SHA-1 hash for internal ports
- 6. Restart SANnav services and confirm normal operation
