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
A buffer overflow vulnerability was identified in some Lenovo printers that could allow an unauthenticated user to trigger a device restart by sending a specially crafted web request.

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 buffer overflow vulnerability in certain Lenovo printers allows unauthenticated remote attackers to cause device denial-of-service (restart) by sending specially crafted web requests to the device's web management interface.

MitigationRestrict network exposure of printer web management interfaces to trusted networks; monitor Lenovo support for firmware updates addressing this vulnerability.

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 printer's web interface or check the device label/menu to confirm it is a Lenovo printer and note the exact model number.
    Affected if The device is a Lenovo printer matching the affected model list.
  2. Check if web management interface is enabled
    Access the printer's control panel or administration menu and verify whether the embedded web server/web management interface feature is turned on.
    Affected if The web management interface is enabled and accessible.
  3. Determine the installed firmware version
    Log into the printer's web management interface and navigate to the Status or Settings page to view the firmware version, or print a configuration page from the control panel.
    Affected if The firmware version falls within the vulnerable version range for the specific model.
  4. Verify network accessibility of the web interface
    From an external system on the network, attempt to access the printer's IP address on common HTTP ports (80, 443, 8080) or use a network scanner to confirm the web service is exposed beyond the local subnet.
    Affected if The web management interface is reachable from untrusted network segments or the internet.

A user is affected if they own a Lenovo printer model with a vulnerable firmware version AND have the web management interface enabled and accessible from the network where the attack could originate.
