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
Dell iDRAC 8 prior to version 2.82.82.82 contain a denial of service vulnerability. An unauthenticated remote attacker could potentially exploit this vulnerability to deny access to the iDRAC webserver.

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

Dell iDRAC 8 versions prior to 2.82.82.82 contain a denial of service vulnerability in the webserver component. An unauthenticated remote attacker can send specially crafted requests to the iDRAC web interface, causing the webserver to become unavailable.

MitigationUpgrade iDRAC 8 firmware to version 2.82.82.82 or later. If immediate patching is not possible, consider network segmentation to limit exposure to untrusted networks and implement monitoring for unusual iDRAC webserver activity.

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 iDRAC version
    Access the iDRAC web interface and check the dashboard for firmware version, or use 'racadm get iDRAC.WebServer.1' via the racadm command-line tool, or query the Redfish API at /redfish/v1/Managers/iDRAC.Embedded.1
    Affected if The firmware version displayed is below 2.82.82.82 (e.g., 2.70.00.00, 2.65.50.10)
  2. Verify iDRAC 8 model
    Confirm the device is specifically iDRAC 8 (not iDRAC 7 or iDRAC 9). Check the product name in the iDRAC web interface under 'Hardware' > 'iDRAC Settings' > 'Overview', or via 'racadm get iDRAC.Info'
    Affected if The model is iDRAC 8 and the version is below 2.82.82.82
  3. Confirm webserver is enabled
    Check if the iDRAC web interface is enabled via 'racadm get iDRAC.WebServer.1' or through the web UI at 'iDRAC Settings' > 'Services' > 'Web Server'. The vulnerability requires the webserver to be active.
    Affected if WebServer.1.Enable is set to 'Enabled' and the firmware version is below 2.82.82.82
  4. Assess network exposure
    Determine if the iDRAC web interface (HTTPS port 443) is accessible from untrusted networks. Check firewall rules, VLAN configuration, and whether iDRAC is on an isolated management network. Use 'racadm get iDRAC.NIC.1' to review IP settings.
    Affected if The iDRAC web interface is exposed to untrusted networks (e.g., directly internet-facing or in an untrusted VLAN) and the version is below 2.82.82.82

You are affected if your Dell iDRAC 8 firmware version is below 2.82.82.82 and the iDRAC webserver is enabled and accessible.

dbcve · scoped
Upgrade available Upgrade to 2.82.82.82 or later
Fixed in 2.82.82.82
Interim mitigation

Upgrade iDRAC 8 firmware to version 2.82.82.82 or later. If immediate patching is not possible, consider network segmentation to limit exposure to untrusted networks and implement monitoring for unusual iDRAC webserver activity.

Recommended fix Moderate confidence

iDRAC 8 Firmware version 2.82.82.82 or later

  1. 1. Identify the current iDRAC 8 firmware version by accessing the iDRAC web interface or using racadm command line tool (e.g., 'racadm get iDRAC.Embedded.1.ServerInfo.1.FirmwareVersion')
  2. 2. Download the iDRAC 8 firmware version 2.82.82.82 or later from the Dell Support site (support.dell.com) for your specific PowerEdge server model
  3. 3. Upload the firmware update via the iDRAC web interface under 'Maintenance' > 'Firmware Update', or use racadm: 'racadm update -f <firmware_image_file>'
  4. 4. Wait for the firmware update to complete; the iDRAC will automatically restart
  5. 5. Verify the updated firmware version matches 2.82.82.82 or later after the reboot
Caveat Firmware updates to iDRAC may require a brief server downtime and should be tested in a non-production environment first; ensure to back up iDRAC configuration before updating
