CVE-2023-35802
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 · uneditedIQ Engine before 10.6r1 on Extreme Network AP devices has a Buffer Overflow in the implementation of the CAPWAP protocol that may be exploited to obtain elevated privileges to conduct remote code execution. Access to the internal management interface/subnet is required to conduct the exploit.
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 confidenceBuffer overflow vulnerability in CAPWAP protocol implementation in IQ Engine prior to version 10.6r1 on Extreme Networks wireless access points, allowing an attacker to obtain elevated privileges and achieve remote code execution.

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 Extreme Networks wireless access point modelLocate the device label or access management console to confirm the device is an Extreme Networks wireless access point. Check system information or show version output for hardware model.Affected if Device is an Extreme Networks AP running IQ Engine software
-
Check IQ Engine version installedAccess the AP CLI or web interface and retrieve the IQ Engine software version. Common command: 'show version' or check system info page.Affected if Version is below 10.6r1 or below 10.6r5 (compare your installed version to these thresholds)
-
Verify CAPWAP protocol configurationCheck CAPWAP settings in the wireless controller or AP configuration. Look for CAPWAP tunnel settings, typically found under wireless network or controller settings.Affected if CAPWAP protocol is enabled or configured on the device
-
Assess management interface exposureReview access control lists, management VLAN settings, and firewall rules to determine if internal management interfaces are exposed to untrusted networks.Affected if Management interfaces are accessible from untrusted networks (this indicates higher exposure to the vulnerability)
A user is affected if their Extreme Networks AP runs IQ Engine version below 10.6r1 (or below 10.6r5) with CAPWAP protocol enabled and management interfaces are reachable by an attacker.

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 · scoped10.6r110.6r5
Upgrade IQ Engine to version 10.6r1 or later; restrict access to internal management interfaces and subnets as a compensating control until patching is possible.
IQ Engine 10.6r1 or later (10.6r5 recommended)
- Identify all Extreme Network AP devices running IQ Engine in the environment
- Check the current IQ Engine version on affected AP devices
- Download IQ Engine version 10.6r1 or later (10.6r5 recommended) from Extreme Portal
- Upgrade the IQ Engine on all affected AP devices to the fixed version
- Verify the upgrade was successful and the version is correct
- Confirm CAPWAP protocol functionality is working properly after upgrade
