CVE-2022-28622
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 · uneditedA potential security vulnerability has been identified in HPE StoreOnce Software. The SSH server supports weak key exchange algorithms which could lead to remote unauthorized access. HPE has made the following software update to resolve the vulnerability in HPE StoreOnce Software 4.3.2.
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 confidenceHPE StoreOnce Software SSH server implements weak key exchange algorithms (KEX) that could allow an attacker to force the use of compromised cryptographic primitives, potentially enabling remote unauthorized access to the system.

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 HPE StoreOnce 3640 modelIdentify if the system is an HPE StoreOnce 3640 appliance by checking the product model through the system management interface, CLI, or hardware label.Affected if The system is not an HPE StoreOnce 3640 model, as this CVE only affects that specific model.
-
Check installed firmware versionAccess the StoreOnce management interface or use the CLI command to retrieve the current firmware version (typically shown in system info or firmware status).Affected if The firmware version is lower than 4.3.2 (for example, 4.2.x, 4.1.x, or earlier).
-
Verify SSH server is enabledCheck if the SSH service is enabled and accessible on the StoreOnce system through the management interface or by attempting an SSH connection to the device.Affected if SSH server is enabled and reachable on the network, exposing the weak KEX algorithms to potential attackers.
-
Confirm SSH exposureDetermine if the SSH port (default 22) is accessible from untrusted networks by reviewing firewall rules or network access lists.Affected if The SSH interface is exposed to external or untrusted networks, increasing the risk of exploitation.
The environment is affected if it is an HPE StoreOnce 3640 with firmware version below 4.3.2 and with SSH server 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.
dbcve · scoped4.3.2
Update to HPE StoreOnce Software 4.3.2 which contains the patched SSH server with strong key exchange algorithms enabled.
StoreOnce Software 4.3.2
- Download HPE StoreOnce Software version 4.3.2 from the HPE support portal (support.hpe.com)
- Review the HPE StoreOnce upgrade documentation and release notes
- Schedule a maintenance window as firmware updates may require system downtime
- Back up current configuration and data
- Upload the 4.3.2 firmware to the StoreOnce 3640 device
- Follow HPE's documented upgrade procedure to apply the firmware
- Verify the upgrade completed successfully
- Confirm SSH configuration no longer accepts weak key exchange algorithms
