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
OS command injection vulnerability exists in Wi-Fi AP UNIT allows. If this vulnerability is exploited, a remote authenticated attacker with an administrative privilege to execute an arbitrary OS command. Affected products and versions are as follows: AC-PD-WAPU v1.05_B04 and earlier, AC-PD-WAPUM v1.05_B04 and earlier, AC-PD-WAPU-P v1.05_B04P and earlier, AC-PD-WAPUM-P v1.05_B04P and earlier, AC-WAPU-300 v1.00_B07 and earlier, AC-WAPUM-300 v1.00_B07 and earlier, AC-WAPU-300-P v1.00_B07 and earlier, and AC-WAPUM-300-P v1.00_B07 and earlier

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 confidence

OS command injection vulnerability in Wi-Fi access point units (AC-PD-WAPU, AC-PD-WAPUM, AC-PD-WAPU-P, AC-PD-WAPUM-P, AC-WAPU-300, AC-WAPUM-300, AC-PD-WAPU-300-P, AC-WAPUM-300-P series) allows remote authenticated attackers with administrative privileges to execute arbitrary OS commands via the web interface or management interface.

MitigationUpdate to a patched firmware version beyond v1.05_B04 (or v1.00_B07 for 300-series) as provided by the vendor; if no patch is available, restrict administrative interface access to trusted networks only and disable remote management on WAN-facing interfaces.

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 device model and firmware version
    Access the device web interface or management console and locate the firmware version information, typically found under System Status, Device Info, or About pages. Compare against the affected version ranges: AC-PD-WAPU/WAPUM/WAPU-P/WAPUM-P models <= 1.05_b04 or <= 1.05_b04p; AC-WAPU-300/WAPUM-300/WAPU-300-P/WAPUM-300-P models <= 1.00_b07.
    Affected if The installed firmware version falls within or below the affected version ranges listed.
  2. Verify web interface is enabled
    Check the device configuration for web-based management settings, typically under Management, Administration, or Access Control settings in the web interface or CLI.
    Affected if The web management interface is enabled, as this is the attack vector for command injection.
  3. Confirm administrative access method exposure
    Inspect network configuration to determine if the management interface (web or CLI) is accessible from WAN or untrusted networks. Look for settings such as 'Remote Management', 'Allow Remote Access', or WAN-side HTTP/HTTPS access.
    Affected if The administrative web interface is reachable from WAN-facing interfaces or untrusted networks, enabling remote exploitation.
  4. Check for existing administrative accounts
    Review the list of configured administrative users in the device, typically under User Management, Administrator Accounts, or Access Control menus.
    Affected if Administrative user accounts exist, as valid admin credentials are required for exploitation of this vulnerability.

The device is affected if it is an Inaba AC-PD-WAPU, AC-PD-WAPUM, AC-PD-WAPU-P, AC-PD-WAPUM-P, AC-WAPU-300, AC-WAPUM-300, AC-PD-WAPU-300-P, or AC-WAPUM-300-P series unit running firmware at or below the affected version thresholds AND the web management interface is accessible remotely.

From vendor data
Upgrade available Upgrade to a release after 1.05_b04p
Interim mitigation

Update to a patched firmware version beyond v1.05_B04 (or v1.00_B07 for 300-series) as provided by the vendor; if no patch is available, restrict administrative interface access to trusted networks only and disable remote management on WAN-facing interfaces.
