CVE-2023-46271
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 · uneditedExtreme Networks IQ Engine before 10.6r1a, and through 10.6r4 before 10.6r5, has a buffer overflow. This issue arises from the ah_webui service, which listens on TCP port 3009 by default.
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 confidenceA buffer overflow vulnerability exists in the ah_webui service of Extreme Networks IQ Engine, which listens on TCP port 3009. This heap or stack overflow can be exploited remotely without authentication, potentially allowing arbitrary code execution with elevated privileges on the affected wireless infrastructure devices.

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.
-
Verify if ah_webui service is exposed on TCP port 3009Use netstat, ss, or a port scanner to check if TCP port 3009 is listening on the device interfaceAffected if Port 3009 is open and accepting connections on a network-facing interface
-
Confirm the IQ Engine version installedAccess the device CLI or web interface and retrieve the firmware/IQ Engine version informationAffected if The installed IQ Engine version is 10.6r4 or earlier, or any version prior to 10.6r1a
-
Determine if remote management or guest SSID features using ah_webui are enabledReview the device configuration to see if the web UI service on port 3009 is enabled for remote administrationAffected if The ah_webui service is enabled and accessible over network interfaces reachable from untrusted networks
A device is affected if it runs IQ Engine version 10.6r4 or earlier (or versions before 10.6r1a) and has the ah_webui service listening on TCP port 3009 accessible from a network where attackers could reach it.

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 · scopedUpgrade IQ Engine to version 10.6r5 or later (or 10.6r1a). If immediate patching is not feasible, restrict network access to TCP port 3009 via firewalls or ACLs to limit exposure to untrusted networks.
IQ Engine 10.6r5
- 1. Identify all Extreme Networks IQ Engine wireless access points and controllers running affected versions (before 10.6r1a, or versions 10.6r1a through 10.6r4).
- 2. Download IQ Engine version 10.6r5 from the official Extreme Networks support portal.
- 3. Plan an upgrade window and ensure backups of current configurations are available.
- 4. Upgrade the affected IQ Engine devices to version 10.6r5 following Extreme Networks standard upgrade procedures.
- 5. After upgrade, verify the ah_webui service (TCP port 3009) is running the patched version.
- 6. Confirm the vulnerability is no longer present through vulnerability scanning or penetration testing.
