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
In PHOENIX CONTACTs WP 6xxx series web panels in versions prior to 4.0.10 a remote attacker with low privileges may use a specific HTTP POST releated to certificate operations to gain full access to the device.

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

A privilege escalation vulnerability in PHOENIX CONTACT WP 6xxx web panels allows remote attackers with low-privilege credentials to gain full administrative access via a specific HTTP POST request related to certificate operations. This authentication bypass in versions prior to 4.0.10 enables complete device compromise.

MitigationUpdate WP 6xxx devices to firmware version 4.0.10 or later. Until patched, restrict network access to the web panel interface using firewall rules or network segmentation to minimize exposure.

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 the device model
    Access the web panel login page or system information page and note the model designation (WP 6070, WP 6101, WP 6121, WP 6156, WP 6185, or WP 6215). This is typically displayed on the login screen or in the System > Information section.
    Affected if The device model is any of the following: WP 6070, WP 6101, WP 6121, WP 6156, WP 6185, or WP 6215.
  2. Check the installed firmware version
    In the web panel interface, navigate to System > Firmware or System > Information to view the current firmware version number. Compare it to the affected version range.
    Affected if The firmware version is below 4.0.10.
  3. Verify web panel network accessibility
    Attempt to access the web panel HTTP/HTTPS ports from an external network segment or use a network scanner to confirm the device web interface is reachable on ports 80/443 (or configured custom ports).
    Affected if The web panel is accessible from network segments outside the trusted administrative zone.
  4. Confirm presence of low-privilege accounts
    Check if any non-administrative user accounts are configured in the web panel under User Management or Access Control settings.
    Affected if Low-privilege user accounts exist in the device user database.

The device is affected if it is a WP 6xxx model (6070/6101/6121/6156/6185/6215) running firmware version below 4.0.10, has its web panel network-accessible, and contains at least one low-privilege user account that could be exploited for privilege escalation via the certificate operations HTTP POST endpoint.

Upgrade available Upgrade to 4.0.10 or later
Fixed in 4.0.10
Interim mitigation

Update WP 6xxx devices to firmware version 4.0.10 or later. Until patched, restrict network access to the web panel interface using firewall rules or network segmentation to minimize exposure.

Recommended fix High confidence

Firmware 4.0.10 (or later) for WP 6070, WP 6101, WP 6121, WP 6156, WP 6185, WP 6215 series

  1. 1. Back up the current device configuration before initiating the upgrade
  2. 2. Obtain firmware version 4.0.10 or later from the PHOENIX CONTACT support website (cert.vde.com or official Phoenix Contact support channels)
  3. 3. Log in to the WP 6xxx web panel with administrative credentials
  4. 4. Navigate to the firmware upgrade or system maintenance section of the web interface
  5. 5. Upload the firmware file (version 4.0.10 or later) and initiate the upgrade process
  6. 6. Wait for the upgrade to complete and the device to reboot
  7. 7. Verify the device is running firmware version 4.0.10 or later by checking the system information
  8. 8. Restore the previously backed up configuration if needed
