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
Certain HP LaserJet Pro print products are potentially vulnerable to Buffer Overflow when performing a GET request to scan jobs.

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

HP LaserJet Pro print products contain a buffer overflow vulnerability in the scan jobs handling functionality. A crafted GET request to the scan jobs endpoint can trigger a buffer overflow, potentially allowing remote code execution or denial of service.

MitigationUpdate HP LaserJet Pro firmware to the latest version. If no patch is available, restrict network access to printer management interfaces and disable unnecessary scan services.

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 printer model
    Check the product label or access the printer's web interface (usually via IP address) to confirm the exact model number matches one of: W1a75a, W1a76a, W1a77a, W1a78a, W1a79a, W1a80a, W1a81a, W1a82a
    Affected if The model is one of the eight listed product numbers
  2. Check the installed firmware version
    Access the printer web interface and navigate to the General or About page, or print a configuration page from the control panel, to find the firmware version string
    Affected if The firmware version is earlier than 002_2322c (for example, 002_2319a or lower)
  3. Verify scan service is enabled
    Check the printer settings via the web interface or control panel to see if scan-to-email, scan-to-network, or scan jobs functionality is turned on
    Affected if Scan jobs handling is enabled and the device is accessible on the network
  4. Confirm network accessibility of the web interface
    Attempt to access the printer's HTTP management interface from a remote host using the IP address, or check firewall rules allowing HTTP/HTTPS to the printer
    Affected if The scan jobs endpoint (typically /scan/jobs or similar path) is reachable over the network

The device is affected if it is one of the eight listed HP LaserJet Pro models, has firmware version lower than 002_2322c, and has scan jobs functionality enabled with network accessibility.

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.

dbcve · scoped
Upgrade available Upgrade to 002_2322c or later
Fixed in 002_2322c
Interim mitigation

Update HP LaserJet Pro firmware to the latest version. If no patch is available, restrict network access to printer management interfaces and disable unnecessary scan services.

Recommended fix High confidence

HP LaserJet Pro firmware version 002_2322c or later for models W1a75a through W1a82a

  1. Identify the specific HP LaserJet Pro model number (W1a75a through W1a82a) from the printer control panel or label
  2. Access the printer's embedded web server by entering its IP address in a web browser
  3. Navigate to the Firmware Update or Administration section to check the current firmware version
  4. Confirm the current firmware version is below 002_2322c
  5. Download the firmware update version 002_2322c or later from HP support website (support.hp.com) for your specific model
  6. Upload and apply the firmware update through the printer's web interface or USB connection following HP's documented update procedure
  7. After the update completes, verify the firmware version has been updated to 002_2322c or later via the web interface or control panel
  8. Restart the printer to ensure the new firmware loads properly
Caveat Firmware updates typically do not introduce breaking changes but ensure stable power and network connectivity during the update process to prevent printer malfunction
