CVE-2025-43018
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 · uneditedCertain HP LaserJet Pro printers may be vulnerable to information disclosure when a non-authenticated user queries a device’s local address book.
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 confidenceHP LaserJet Pro printers contain an information disclosure vulnerability where a non-authenticated remote attacker can query the device's local address book, exposing stored contact information without any authentication credentials.
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 checksWork through these to decide whether this CVE applies to you.
-
Identify the printer modelCheck the printer's web interface, control panel, or print a configuration page to confirm the model number. Look for one of: W1a75a, W1a76a, W1a77a, W1a81a, W1a82a, W1a79a, W1a80a, W1a78a.Affected if The printer model matches one of the affected product codes.
-
Check the firmware versionAccess the printer's embedded web server (EWS) via its IP address, navigate to the General or Information tab, and record the firmware version displayed.Affected if The firmware version is below 002.2508a.
-
Verify address book accessibilityFrom a network-connected system, attempt to access the address book endpoint on the printer without providing any login credentials. This is typically found at a URL path like /hp/device/addressbook or /addressbook on the printer's IP.Affected if The address book data is returned without requiring authentication.
-
Confirm remote management is enabledIn the printer EWS, go to the Networking or Security tabs and check if remote management, embedded web server, or network scanning features are enabled.Affected if Remote management interfaces are accessible over the network.
The printer is affected if it is one of the listed models, runs firmware below 002.2508a, and allows unauthenticated access to the local address book via its web interface.

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 · scoped002.2508a
Restrict network access to printer management interfaces via firewall rules or network segmentation; apply vendor firmware updates when available; disable unused remote access features.
Firmware version 002.2508a or later
- Identify your HP LaserJet Pro model number (W1a75a, W1a76a, W1a77a, W1a78a, W1a79a, W1a80a, W1a81a, or W1a82a)
- Access the printer's embedded web server by entering its IP address in a web browser
- Navigate to the 'General' or 'Information' tab to check the current firmware version
- If the firmware version is below 002.2508a, download the latest firmware update from HP support (support.hp.com) for your specific model
- Follow HP's firmware update instructions, typically via the printer's firmware upgrade feature in the web interface or using the HP Smart software
