CVE-2024-4282
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 OVA before SANnav 2.3.1b enables SHA1 deprecated setting for SSH for port 22.
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 confidenceBrocade SANnav OVA versions prior to 2.3.1b use the deprecated SHA1 hashing algorithm for SSH key exchange on port 22, making cryptographic communications vulnerable to collision attacks and man-in-the-middle exploits.

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.
-
Confirm Brocade SANnav OVA is installedLocate the SANnav installation directory or check system services for Brocade SANnav processesAffected if The product is not present on the system
-
Determine installed SANnav versionCheck the SANnav version information through the management interface or installation filesAffected if The version is identified as lower than 2.3.1b (e.g., 2.3.0, 2.2.x, etc.)
-
Verify SSH service is enabled on port 22Test connectivity to port 22 on the SANnav host using telnet or nc: nc -zv <host> 22Affected if Port 22 is open and accepting SSH connections
-
Inspect SSH key exchange algorithmsUse verbose SSH debugging to list supported key exchange methods: ssh -vvv -o KexAlgorithms=+diffie-hellman-group1-sha1 user@<sannav_host> 2>&1 | grep -i sha1Affected if SHA1-based key exchange algorithms (such as diffie-hellman-group1-sha1) are listed as available or preferred
A user is affected if Brocade SANnav OVA version is below 2.3.1b AND SSH service is enabled on port 22 with SHA1 key exchange algorithms available

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 · scoped2.3.1b
Upgrade Brocade SANnav OVA to version 2.3.1b or later to remove the insecure SHA1 SSH configuration and restore secure cryptographic defaults.
SANnav 2.3.1b or later
- 1. Obtain SANnav version 2.3.1b or later from the Broadcom support portal (support.broadcom.com)
- 2. Create a full backup of the current SANnav configuration and data
- 3. Deploy the new SANnav 2.3.1b OVA as a fresh installation, or follow Broadcom's upgrade procedure to update the existing appliance
- 4. After upgrade, verify that SSH on port 22 no longer uses the deprecated SHA1 algorithm by reviewing the SSH daemon configuration
- 5. Confirm SSH connectivity works properly with stronger cryptographic algorithms (SHA-256 or SHA-512 based key exchange and MACs)
- 6. Validate all SANnav management functions are operational post-upgrade
