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
Insufficient Solution DLL Signature Validation allows potential execution of arbitrary code in HP LaserJet Enterprise printers, HP PageWide Enterprise printers, HP LaserJet Managed printers, HP OfficeJet Enterprise printers before 2308937_578479, 2405087_018548, and other firmware versions.

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

Insufficient Solution DLL signature validation in HP enterprise printer firmware allows unauthenticated attackers to load and execute arbitrary code by deploying malicious DLL files to the printer. This is a code execution vulnerability at the firmware level with network accessibility.

MitigationUpdate affected HP LaserJet Enterprise, PageWide Enterprise, LaserJet Managed, and OfficeJet Enterprise printers to firmware versions 2308937_578479, 2405087_018548 or later to remediate the DLL signature validation flaw.

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 (model) on the printer label or access it via the printer's embedded web server (EWS) at the printer's IP address
    Affected if The model number matches one of the affected product codes: L2683a, L2717a, L2762a, J7z13a, Z5g79a, L3u42a, J7z08a, J7z14a
  2. Check installed firmware version
    Access the printer's embedded web server (EWS) by navigating to the printer's IP address in a web browser. Navigate to the 'General' or 'Information' tab to view the firmware version string
    Affected if The firmware version string is lower than the specified fixed version for your model (for example, for L2683a: < 2405087_018552, for L2717a: < 2308937_578486, etc.)
  3. Verify Solution DLL feature status
    In the printer's embedded web server, navigate to the 'Security' or 'Solutions' settings section. Look for settings related to 'Solution DLL Loading', 'DLL Signing', or 'Code Signing' verification
    Affected if The Solution DLL loading feature is enabled (the exact setting name may vary by printer model)

If the printer model is in the affected list AND the firmware version is below the fixed version threshold AND the Solution DLL loading feature is enabled, the printer is vulnerable to CVE-2017-2750.

Interim mitigation

Update affected HP LaserJet Enterprise, PageWide Enterprise, LaserJet Managed, and OfficeJet Enterprise printers to firmware versions 2308937_578479, 2405087_018548 or later to remediate the DLL signature validation flaw.

Recommended fix Moderate confidence

Firmware version 2405087_018548 or 2308937_578479 (depending on product model)

  1. 1. Identify the exact HP printer model number (e.g., L2683a, L2717a, etc.) from the product label or control panel.
  2. 2. Check the current firmware version via the printer's control panel (usually under Settings > Service > Firmware Date Code) or embedded web server (EWS) at https://<printer-ip>/hp/device
  3. 3. Navigate to HP Support (support.hp.com) and enter the specific printer model number.
  4. 4. Download the latest firmware from the HP support page - look for firmware version 2405087_018548 or later (or 2308937_578479 or later depending on product line).
  5. 5. Access the printer's EWS at https://<printer-ip>/hp/device and go to the Firmware Update section.
  6. 6. Upload and install the downloaded firmware file following the on-screen instructions.
  7. 7. After installation, verify the new firmware version matches the expected fixed version.
  8. 8. Restart the printer to ensure the firmware update is fully applied.
Caveat Firmware updates may temporarily interrupt printer availability; ensure print jobs are paused before updating
