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 printers may be vulnerable to information disclosure leading to credential exposure by altering the scan/send destination address and/or modifying the LDAP Server.

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 printers contain a vulnerability allowing unauthorized modification of scan/send destination addresses or LDAP server configuration, leading to exposure of stored credentials. The issue appears to involve insufficient authentication or authorization controls on printer management functions, potentially allowing network-based attackers to redirect scanned documents or intercept authentication credentials.

MitigationImplement network segmentation to restrict printer management interfaces to trusted networks, ensure strong authentication is required for configuration changes, and verify LDAP connections use secure authentication mechanisms. Apply any available firmware updates from HP.

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 printer model
    Locate the product number on the printer label or access the Embedded Web Server (EWS) via the printer's IP address and check the General or Information page. The product number will be in the format W1y47a, 7kw48a, 7kw49a, 7kw50a, 7kw51a, 7kw54a, 7kw55a, or 7kw56a.
    Affected if The printer model is one of these eight product numbers.
  2. Check installed firmware version
    Access the Embedded Web Server, navigate to the General or About page, and locate the firmware version field. Alternatively, print a configuration page from the printer control panel to find the firmware version.
    Affected if The firmware version is lower than 002.2539e (for example, 002.2538a or earlier).
  3. Verify remote management interface accessibility
    Attempt to access the printer's Embedded Web Server over the network on the default HTTP/HTTPS ports (typically 80 or 443) using the printer's IP address. Check if the interface is reachable without VPN or network restrictions.
    Affected if The EWS is accessible from untrusted network segments or the internet.
  4. Check if LDAP configuration is present
    In the Embedded Web Server, navigate to the Network Settings, LDAP, or Authentication configuration sections. Look for configured LDAP server settings including server address, base DN, and bind credentials.
    Affected if An LDAP server is configured and the printer stores authentication credentials for LDAP binding.
  5. Inspect scan/send destination configuration
    In the Embedded Web Server, go to Scan, Digital Sending, or Network Folder/Email configuration sections. Review the configured scan destinations, email addresses, or network share paths.
    Affected if Scan or send destinations are configured and could be redirected by an attacker.

The environment is affected if the printer model matches one of the eight product codes and the firmware version is below 002.2539e, with remote management and LDAP or scan destinations configured.

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 002.2539e or later
Fixed in 002.2539e
Interim mitigation

Implement network segmentation to restrict printer management interfaces to trusted networks, ensure strong authentication is required for configuration changes, and verify LDAP connections use secure authentication mechanisms. Apply any available firmware updates from HP.

Recommended fix Moderate confidence

HP LaserJet Pro firmware version 002.2539e or later

  1. Identify the exact printer model number (W1y47a, 7kw48a, 7kw49a, 7kw50a, 7kw51a, 7kw54a, 7kw55a, or 7kw56a) from the printer control panel or label
  2. Access the HP Embedded Web Server (EWS) by entering the printer's IP address in a web browser
  3. Navigate to the General tab or Firmware Update section
  4. Check the current firmware version under System Information or About
  5. If the firmware version is below 002.2539e, download the latest firmware update from support.hp.com for your specific model
  6. In the EWS firmware update section, select the downloaded firmware file and initiate the update
  7. Wait for the firmware upload and installation to complete (do not power off the printer)
  8. After reboot, verify the new firmware version displays 002.2539e or later
