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

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 exists in the nw_interface.html web component of multiple SHARP multifunction printer models. This allows remote attackers to inject and execute arbitrary operating system commands via unspecified vectors in the device's web management interface.

MitigationApply vendor-supplied firmware updates from SHARP for affected MFP models. If patches are unavailable, restrict network access to the MFP web management interface to trusted networks or disable remote management features.

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 MFP model
    Access the device's web management interface or check the physical device label to confirm the exact model number. Look for models: BP-30c25, BP-30c25t, BP-30c25y, BP-30c25z, BP-30m28, BP-30m28t, BP-30m31, BP-30m31t.
    Affected if The device model matches any of the listed affected models.
  2. Verify web management interface is enabled
    Attempt to access the device's web interface by entering the device IP address in a web browser. Look for a login page or web management portal.
    Affected if The web management interface is accessible and responds to HTTP/HTTPS requests.
  3. Check if remote management is enabled
    Log into the web interface and navigate to the network settings or remote management configuration section. Look for options related to 'Remote Access', 'Web Remote', or 'Remote Management'.
    Affected if Remote management or web remote access features are turned on, allowing network-based access to the management interface.
  4. Confirm nw_interface.html component exists
    Access the specific web component by navigating to http://[device IP]/nw_interface.html or similar path within the web interface structure.
    Affected if The nw_interface.html page loads, indicating the vulnerable component is present on the device.

You are affected if your device is one of the Sharp BP models listed (30c25, 30c25t, 30c25y, 30c25z, 30m28, 30m28t, 30m31, 30m31t) and the web management interface is accessible, since all firmware versions of these models are vulnerable.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

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.

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

Apply vendor-supplied firmware updates from SHARP for affected MFP models. If patches are unavailable, restrict network access to the MFP web management interface to trusted networks or disable remote management features.
