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
Cumin, as used in Red Hat Enterprise MRG 2.4, allows remote attackers to cause a denial of service (CPU and memory consumption) via a crafted Ajax update request.

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

Cumin (a component in Red Hat Enterprise MRG 2.4) fails to properly handle malformed Ajax update requests, allowing remote attackers to trigger excessive CPU and memory consumption leading to denial of service.

MitigationUpdate to a patched version of Cumin or Red Hat Enterprise MRG, or implement request validation/limiting on Ajax endpoints to reject crafted requests.

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. Verify Red Hat Enterprise MRG version
    Check the installed version of Red Hat Enterprise MRG by running 'rpm -q mrg-release' or checking /etc/redhat-release for MRG-specific entries
    Affected if The installed version equals 2.4 exactly
  2. Confirm Cumin component is present
    Check if the Cumin package is installed: run 'rpm -qa | grep -i cumin' or look for /usr/bin/cumin in the filesystem
    Affected if Cumin is installed on the system
  3. Identify Cumin web interface exposure
    Check if Cumin's web service is running and accessible: look for processes listening on typical web ports (8000, 8080) or check /etc/cumin/cumin.conf for web server configuration
    Affected if Cumin's web interface with Ajax update functionality is exposed and accessible over the network
  4. Verify Ajax endpoint accessibility
    Attempt to access Cumin's Ajax update endpoints (typically at /update or /ajax paths) or examine web server logs for requests to these endpoints
    Affected if The Ajax update endpoints are reachable without authentication or proper request validation

The environment is affected if running Red Hat Enterprise MRG 2.4 with Cumin installed and its web interface with Ajax update endpoints exposed to network requests.
