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 user with device administrative privileges can change existing SMTP server settings on the device, without having to re-enter SMTP server credentials. By redirecting send-to-email traffic to the new server, the original SMTP server credentials may potentially be exposed.

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 confidence

A device administrator can modify existing SMTP server settings without re-authenticating the stored SMTP credentials. This allows redirection of email traffic to an attacker-controlled server, causing the original SMTP username/password to be transmitted to the malicious server.

MitigationRequire re-authentication of SMTP credentials before allowing modification of SMTP server settings, ensuring the legitimate user's identity is verified before sensitive configuration changes.

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 your HP printer model
    Check the product label on the device or access the printer's web interface (Embedded Web Server) to view the model number. Look for product codes W1a75a, W1a76a, W1a77a, W1a78a, W1a79a, W1a80a, W1a81a, or W1a82a.
    Affected if The model is one of the listed product codes and falls within the affected firmware range.
  2. Check the installed firmware version
    Access the printer's Embedded Web Server, navigate to the General or Support Information page, and locate the firmware version field. Alternatively, print a configuration page from the device menu to view the firmware version.
    Affected if The firmware version is lower than 002_2413A (for example, 002_2401 or earlier).
  3. Verify SMTP configuration status
    Log into the printer's Embedded Web Server as an administrator. Navigate to the Email/SMTP or Settings > Email setup section. Check if an SMTP server is configured and enabled.
    Affected if SMTP is configured with stored credentials (username/password) and the firmware version is below 002_2413A.
  4. Review administrator authentication behavior
    In the SMTP settings section, attempt to modify the SMTP server address or port. Observe whether the system prompts for re-authentication of the existing SMTP credentials before allowing the change.
    Affected if The server address can be modified without requiring re-entry or verification of the stored SMTP username and password.

Your environment is affected if you have an HP printer model W1a75a through W1a82a with firmware version below 002_2413A and SMTP is configured with stored credentials that are not re-authenticated when modifying server settings.

Generated from the published advisory. Verify against your own configuration.

Require re-authentication of SMTP credentials before allowing modification of SMTP server settings, ensuring the legitimate user's identity is verified before sensitive configuration changes.

Recommended fix High confidence

Firmware version 002_2413A or later

  1. Identify the specific HP printer model (W1a75a through W1a82a series) from the affected product list
  2. Navigate to HP support website (support.hp.com) and locate the firmware download section for your specific printer model
  3. Download the firmware update version 002_2413A or later
  4. Access the printer's Embedded Web Server (EWS) by entering the printer's IP address in a web browser
  5. Log in with administrator credentials
  6. Locate the Firmware Update section in the EWS settings
  7. Upload and install the downloaded firmware file
  8. After the update completes, verify the firmware version displays as 002_2413A or higher in the EWS or printer control panel
Caveat Firmware update may reset some device settings to defaults; back up or document current configuration before upgrading
