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 · unedited
Buffer Overflow vulnerability in Extreme Networks IQ Engine before 10.6r1a, and through 10.6r4 before 10.6r5, allows an attacker to execute arbitrary code via the implementation of the ah_auth service

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 confidence

A buffer overflow vulnerability exists in the ah_auth service of Extreme Networks IQ Engine wireless firmware. The flaw allows remote attackers to execute arbitrary code via crafted input to this authentication service. Affected versions include those before 10.6r1a and 10.6r4 before 10.6r5.

MitigationUpgrade IQ Engine firmware to version 10.6r5 or later to remediate this vulnerability. If running older branches, upgrade to 10.6r1a or the latest stable release for that branch.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify IQ Engine installation
    Access the wireless controller or access point CLI and run commands such as 'show version', 'show system info', or check the web interface dashboard to confirm Extreme Networks IQ Engine firmware is installed.
    Affected if The device is not running Extreme Networks IQ Engine firmware - this CVE only applies to that specific product line.
  2. Locate firmware version
    Execute 'show version' or 'show firmware version' in the CLI. The output will display the current IQ Engine version number (for example, 10.6r4 or 10.6r5).
    Affected if Unable to determine the firmware version - you cannot assess exposure without knowing the installed version.
  3. Compare version against affected ranges
    Compare the installed version to these affected ranges: any version before 10.6r1a, or version 10.6r4 through 10.6r4.x. Versions 10.6r5 and later, or 10.6r1a (inclusive), are not affected.
    Affected if The installed version falls within 'before 10.6r1a' OR is '10.6r4 through 10.6r4.x' (any 10.6r4 release before 10.6r5).
  4. Verify ah_auth service presence
    Check if the ah_auth authentication service is running or enabled on the device. This may be visible via 'show process', 'show services', or by reviewing the service configuration in the web interface under Wireless Services or Authentication settings.
    Affected if The ah_auth service is not present or not configured - the buffer overflow only affects systems where this specific authentication service is enabled.
  5. Confirm network exposure
    Review firewall rules, access point group policies, and network segmentation to determine if the ah_auth service is reachable from untrusted networks. Check if management interfaces are exposed to LAN/WAN or guest networks.
    Affected if The ah_auth service is directly accessible from untrusted or external networks - the vulnerability is exploitable remotely via crafted input to this service.

A system is affected if it runs Extreme Networks IQ Engine firmware version 10.6r4 through 10.6r4.x (before 10.6r5) or any version before 10.6r1a, and has the ah_auth service enabled and network-accessible.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade IQ Engine firmware to version 10.6r5 or later to remediate this vulnerability. If running older branches, upgrade to 10.6r1a or the latest stable release for that branch.

Recommended fix Moderate confidence

Extreme Networks IQ Engine 10.6r5

  1. 1. Identify the current IQ Engine version installed on the affected Extreme Networks device
  2. 2. If the current version is before 10.6r1a, upgrade to version 10.6r1a or later
  3. 3. If the current version is 10.6r1a through 10.6r4, upgrade to version 10.6r5 or later
  4. 4. Verify the upgrade was successful by checking the IQ Engine version
  5. 5. Test the ah_auth service functionality to ensure proper operation after upgrade
