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 a buffer overflow vulnerability in the arg4 and arg9 parameters of several functionalities of the web application that would allow an authenticated attacker to perform a Denial of Service attack, crashing the device, or 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 · moderate confidence

Buffer overflow vulnerability in Kyocera printer web application (ECOSYS M5526cdw and potentially other models) affecting arg4 and arg9 parameters in multiple functionalities. Requires authenticated access to exploit, allowing DoS via device crash or potential arbitrary code execution.

MitigationApply vendor firmware patches when available; until then, restrict web interface access to authorized personnel only via network segmentation and authentication controls, and monitor for exploitation attempts.

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 the Kyocera printer model
    Access the printer's web interface or print a configuration page to confirm the exact model number (e.g., Ecosys M5526cdw)
    Affected if The model is Kyocera Ecosys M5526cdw or other potentially affected models from Kyocera's product line
  2. Check the installed firmware version
    Access the printer web interface System or Status page, or print a configuration/status page, and locate the firmware version field
    Affected if The firmware version is exactly 2r7_2000.001.701
  3. Verify if the web application interface is enabled and accessible
    Attempt to access the printer's web interface via HTTP/HTTPS on the configured IP address
    Affected if The web interface is accessible on the network without restriction
  4. Confirm if authentication is required for web interface access
    Test accessing the web interface - verify that login credentials are enforced for all functional areas
    Affected if The web interface does not require authentication or uses default credentials, allowing unauthorized authenticated access

You are affected if you have a Kyocera Ecosys M5526cdw with firmware version 2r7_2000.001.701 and its web interface is network-accessible without proper authentication controls.
