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
The web interface of the affected devices processes a cookie value improperly, leading to a stack buffer overflow. More precisely, giving too long character string to MFPSESSIONID parameter results in a stack buffer overflow. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

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

Stack buffer overflow vulnerability in the web interface allows remote code execution via an overly long MFPSESSIONID cookie value, caused by improper validation of the cookie parameter before copying to a fixed-size stack buffer.

MitigationApply the vendor-supplied firmware or software update to patch the buffer overflow vulnerability; until patched, minimize exposure of the affected web interfaces 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. Identify the product and web interface
    Determine the manufacturer, model, and software version of the device or application exposing a web interface. Look for the web service process and note its version information.
    Affected if The product has a web interface that uses MFPSESSIONID cookies and the version is unknown or within an unpatched release range
  2. Verify MFPSESSIONID cookie usage
    Send an HTTP request to the web interface and inspect the response headers and Set-Cookie directives. Confirm whether the MFPSESSIONID cookie is being set by the server.
    Affected if The web interface sets an MFPSESSIONID cookie, indicating the vulnerable code path may be present
  3. Check web interface network exposure
    Determine if the web interface is accessible from network interfaces other than localhost. Review firewall rules, NAT configurations, or access control lists that govern access to the web service port.
    Affected if The web interface is exposed to untrusted networks, increasing the risk of remote exploitation
  4. Compare installed version to patch status
    Locate the installed software or firmware version through the web interface admin panel, system information page, or command-line tools. Check vendor security advisories for CVE-2024-28038 to determine if your version includes the fix.
    Affected if The installed version predates the vendor patch for CVE-2024-28038 or the patch status is unknown

You are likely affected if your product has a web interface using MFPSESSIONID cookies, the version is unpatched, and the interface is network-accessible.

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.
