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 devices are potentially vulnerable to a Cross-Site Scripting (XSS) attack via the web management interface of 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

Cross-Site Scripting (XSS) vulnerability in the web management interface of certain HP LaserJet Pro devices allows attackers to inject malicious scripts through the interface, potentially compromising user sessions or executing arbitrary code in the context of the victim's browser.

MitigationApply the vendor-supplied firmware update or patch for affected HP LaserJet Pro devices. If no patch is available, consider network segmentation to limit access to the device management interface and implement additional input validation at the network perimeter.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 device model and firmware code
    Access the printer's web management interface (typically http://[printer-ip] or https://[printer-ip]) and navigate to the General or Information page to view the product model and firmware code (such as Cz181a, Cz182a, Cz187a, Cz183a, Cz172a, Cz173a, Cz176a, or Cz177a). Alternatively, check the information page printed from the device control panel or query via SNMP.
    Affected if The device model displays one of the affected firmware codes: Cz181a, Cz182a, Cz187a, Cz183a, Cz172a, Cz173a, Cz176a, or Cz177a.
  2. Check firmware version and date
    In the web management interface, locate the firmware version or build date information, typically found under General, Support, or About sections. This is often displayed as a date (YYYY-MM-DD format) or a version number with an associated date.
    Affected if The firmware build date is before 2023-03-30, or the version number corresponds to a build earlier than the March 30, 2023 release.
  3. Confirm web management interface is accessible
    Attempt to reach the printer's web interface by browsing to the printer's IP address on ports 80 or 443. Verify the interface loads and displays the login or status page.
    Affected if The web management interface is reachable and functional on the network.

A device is affected if it carries one of the specific firmware codes (Cz181a, Cz182a, Cz187a, Cz183a, Cz172a, Cz173a, Cz176a, Cz177a) with a build date earlier than 2023-03-30 and has its web management interface enabled.

dbcve · scoped
Upgrade available Upgrade to 2023-03-30 or later
Fixed in 2023-03-30
Interim mitigation

Apply the vendor-supplied firmware update or patch for affected HP LaserJet Pro devices. If no patch is available, consider network segmentation to limit access to the device management interface and implement additional input validation at the network perimeter.

Recommended fix Moderate confidence

Firmware version 2023-03-30 or later for HP LaserJet Pro Cz181a/Cz182a/Cz187a/Cz183a/Cz172a/Cz173a/Cz176a/Cz177a

  1. Access the printer's web management interface through its IP address
  2. Navigate to the firmware or administration section
  3. Check the current firmware version (should be pre-2023-03-30 for affected devices)
  4. Download the latest firmware update from HP support website for your specific model (Cz181a, Cz182a, Cz187a, Cz183a, Cz172a, Cz173a, Cz176a, or Cz177a)
  5. Upload and install the firmware update through the web interface or HP Smart app
  6. Verify the firmware has been updated to version 2023-03-30 or later
  7. Confirm the vulnerability is remediated by verifying the web management interface handles input properly
Caveat Printer firmware updates typically require brief downtime; ensure print jobs are paused and configuration is backed up before upgrading
