CVE-2024-43689
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 · uneditedStack-based buffer overflow vulnerability exists in ELECOM wireless access points. By processing a specially crafted HTTP request, arbitrary code may be executed.
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 stack-based buffer overflow vulnerability exists in ELECOM wireless access points. The vulnerability is triggered by sending a specially crafted HTTP request to the affected device, which can lead to arbitrary code execution with high severity (CVSS 9.8).

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 modelLocate the wireless access point in your network inventory or physically inspect the device label. Confirm it is an ELECOM Wab I1750 or Wab S1167 model.Affected if The device is not an ELECOM Wab I1750 or Wab S1167 model.
-
Check the installed firmware versionAccess the device management interface or use the vendor-supplied administration tool to view the current firmware version. Compare this version number against the affected ranges: Wab I1750 if version is 1.5.10 or lower, Wab S1167 if version is 1.5.6 or lower.Affected if The installed firmware version falls within or below the affected ranges (1.5.10 for Wab I1750, 1.5.6 for Wab S1167).
-
Verify HTTP management interface is enabledCheck the device network settings or management console to determine if the HTTP (port 80) management service is currently active. Note that the vulnerability is triggered via HTTP requests.Affected if HTTP management interface is enabled and accessible.
-
Assess network accessibility of the management interfaceDetermine whether the device management interface is reachable from untrusted networks, the internet, or non-segmented network segments. Attempt a connection to port 80 on the device IP address from an external location if permitted by your security policies.Affected if The HTTP management interface is exposed to untrusted networks or the internet.
You are affected if you have an ELECOM Wab I1750 or Wab S1167 device running firmware at or below the affected version with HTTP management enabled and accessible from your network.

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.
From vendor dataApply the vendor-supplied firmware patch when available. Until then, restrict network access to the management interface, disable HTTP if possible and use HTTPS, and place affected devices behind a segmented network.
