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
Some Kyocera printers (such as the ECOSYS M5526cdw 2R7_2000.001.701) were affected by multiple buffer overflow vulnerabilities in the IPP service. This would allow an unauthenticated attacker to cause a Denial of Service (DoS), and potentially execute arbitrary code on 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 · high confidence

Multiple buffer overflow vulnerabilities in the IPP (Internet Printing Protocol) service on Kyocera printers allow unauthenticated attackers to cause denial of service and potentially achieve arbitrary code execution. The critical CVSS score of 9.8 reflects the ease of exploitation and severe impact.

MitigationApply vendor-supplied firmware updates to affected Kyocera devices. In the interim, disable or restrict IPP service access through network segmentation and firewall rules to limit exposure to untrusted networks.

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. Confirm the printer model
    Access the printer web interface or print a status/configuration page to identify the device model. Look for 'Ecosys M5526cdw' in the device information
    Affected if The device is not a Kyocera Ecosys M5526cdw
  2. Check the installed firmware version
    In the printer web interface, navigate to the Status or System Information section to view the firmware version. Alternatively, print a status page from the device control panel
    Affected if The firmware version is 2r7_2000.001.701
  3. Verify IPP service is enabled
    In the printer web interface, go to Network Settings, Port Settings, or Printing Protocols. Locate the IPP (Internet Printing Protocol) setting and confirm whether it is turned on
    Affected if IPP service is enabled on the device
  4. Determine IPP network exposure
    Check the printer's IP address accessibility and review any firewall or network rules. IPP typically uses port 631. Verify whether this port is reachable from untrusted network segments
    Affected if IPP is enabled and accessible from untrusted networks or the internet

If the device is a Kyocera Ecosys M5526cdw with firmware version 2r7_2000.001.701 and IPP is enabled and network-accessible, it is likely affected by CVE-2019-13204
