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 command injection in a HTTP POST request releated to font configuration 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 · high confidence

A command injection vulnerability in PHOENIX CONTACT WP 6xxx series web panels (versions prior to 4.0.10) allows remote authenticated attackers with low privileges to execute arbitrary commands via specially crafted HTTP POST requests related to font configuration operations, potentially gaining full device access.

MitigationUpgrade PHOENIX CONTACT WP 6xxx series web panels to version 4.0.10 or later to remediate this vulnerability. Restrict network access to the web panel interface as an interim compensating control.

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 device's web interface or check the physical device label to confirm it is a PHOENIX CONTACT WP series model (WP 6070 WVPS, WP 6101 WXPS, WP 6121 WXPS, WP 6156 WHPS, WP 6185 WHPS, or WP 6215 WHPS).
    Affected if The device is one of the listed WP 6xxx models.
  2. Check the firmware version
    Log into the web panel interface and navigate to System Information or Device Status page to view the installed firmware version. Alternatively, check via the device's administration console or startup logs.
    Affected if The firmware version is lower than 4.0.10.
  3. Verify web panel HTTP service is enabled
    Attempt to access the device's web interface via HTTP (port 80) or HTTPS (port 443) from a network-connected host. Confirm the web service responds.
    Affected if The web panel HTTP/HTTPS service is accessible on the network.
  4. Confirm font configuration feature is accessible
    Locate the font configuration or font management section within the web panel's settings menu. Check if unauthenticated or low-privilege authenticated users can access font upload or font configuration operations.
    Affected if Font configuration operations are available to authenticated users with low privileges.

The device is affected if it is a PHOENIX CONTACT WP 6xxx model with firmware version below 4.0.10 and the web panel interface with font configuration features is network-accessible.
