CVE-2024-23978
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 · uneditedHeap-based buffer overflow vulnerability exists in HOME SPOT CUBE2 V102 and earlier. By processing invalid values, arbitrary code may be executed. Note that the affected products are no longer supported.
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 confidenceA heap-based buffer overflow vulnerability exists in the HOME SPOT CUBE2 V102 and earlier wireless router firmware. The vulnerability is triggered when the device processes invalid values, allowing an attacker to overflow heap memory and potentially execute arbitrary code with the privileges of the affected service.

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 the device modelAccess the router web interface or check the physical device label to confirm the exact model number is 'HOME SPOT CUBE2' from KddiAffected if The device model is not Kddi Home Spot Cube 2, the vulnerability does not apply
-
Determine the installed firmware versionLog into the router administration panel and navigate to the firmware/version information page, or use the command 'sysversion' or check the system status page if available via web interface or telnet/SSHAffected if The firmware version is v102 or any version earlier than v102 (such as v101, v100, etc.)
-
Verify network accessibility of the deviceConfirm the device is reachable on the network by pinging its IP address and checking if management interfaces (HTTP/HTTPS on common ports like 80, 443, 8080) are accessibleAffected if The device is directly accessible from untrusted network segments without firewall protection
-
Check for unauthorized configuration changesReview the router configuration settings, particularly wireless security settings, DHCP configurations, and any port forwarding rules, comparing against known-good baselines if availableAffected if Unexpected configuration changes exist that were not made by authorized administrators
A user is affected if they have a Kddi Home Spot Cube 2 device running firmware version v102 or earlier, as this is the only product and version range specified for this CVE.
Generated from the published advisory. Verify against your own configuration.
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 · scopedSince the affected products are end-of-life and no longer supported by the vendor, there is no security patch available. Organizations should replace affected devices with supported hardware. If immediate replacement is not feasible, isolate affected devices on dedicated network segments and implement additional monitoring for signs of exploitation.
- Replace the end-of-life Home Spot Cube 2 device with a supported router or mesh system
- Since the vendor explicitly states the affected products are no longer supported, no firmware patch or upgrade is available
- If continued use is unavoidable, isolate the device on a dedicated network segment with strict firewall rules to limit exposure
