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 Integrated Remote Access Controller (iDRAC) 7/8 before 2.21.21.21 has XXE.

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

Dell iDRAC 7/8 versions before 2.21.21.21 contain an XML External Entity (XXE) injection vulnerability. This allows remote unauthenticated attackers to inject malicious XML entities, potentially enabling file disclosure, denial of service, or server-side request forgery (SSRF) attacks against the underlying system.

MitigationUpgrade Dell iDRAC firmware to version 2.21.21.21 or later. If upgrading is not immediately possible, restrict network access to the iDRAC management interface to trusted networks only, as XXE can be exploited without authentication.

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. Locate iDRAC web interface IP address
    Identify the IP address of the iDRAC management interface on your network. This is typically accessible via the server's BMC IP address, often found in network documentation or via DHCP server logs.
    Affected if You cannot locate an iDRAC IP address because the product may not be in use.
  2. Access iDRAC firmware version via web UI
    Open a browser to the iDRAC IP address (e.g., https://[ip-address]) and navigate to the Overview or About page in the iDRAC web interface. The firmware version is displayed there.
    Affected if The iDRAC version displayed is 2.20.20.20 or lower.
  3. Verify version via command line
    If you have administrative access to the host server, use the racadm command: racadm getsysinfo or racadm fwversion. Alternatively, use IPMI: ipmitool -I lanplus -H [ip] -U root -P [password] fru print.
    Affected if The reported firmware version is 2.20.20.20 or lower.
  4. Confirm web service is exposed
    Verify that the iDRAC web interface (HTTPS port 443) is reachable from network segments outside your trusted management network using a port scanner or curl: curl -k https://[idrac-ip]/
    Affected if The iDRAC web interface is accessible from untrusted networks and version is 2.20.20.20 or lower.

You are affected if your Dell iDRAC 7/8 firmware version is 2.20.20.20 or lower and the web management interface is network-accessible.

dbcve · scoped
Upgrade available Upgrade to a release after 2.20.20.20
Interim mitigation

Upgrade Dell iDRAC firmware to version 2.21.21.21 or later. If upgrading is not immediately possible, restrict network access to the iDRAC management interface to trusted networks only, as XXE can be exploited without authentication.

Recommended fix High confidence

iDRAC firmware version 2.21.21.21 or later

  1. 1. Log into the Dell iDRAC web interface or access via racadm CLI
  2. 2. Navigate to the Firmware Update section (iDRAC Settings > Update and Rollback)
  3. 3. Download the iDRAC firmware version 2.21.21.21 or later from dell.com/support
  4. 4. Upload the firmware file to the iDRAC
  5. 5. Apply the firmware update and allow the iDRAC to reboot
  6. 6. After reboot, verify the firmware version is 2.21.21.21 or higher
  7. 7. Confirm XXE vulnerability is resolved by verifying XML parsing configuration or retesting
