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 checksWork through these to decide whether this CVE applies to you.
-
Identify Oracle Sun ILOM installationAccess the server's BMC/ILOM interface via IPMI or SSH (typically at the BMC IP address). Confirm the product is Oracle Sun Integrated Lights Out Manager (ILOM).Affected if The managed device runs Oracle Sun ILOM firmware
-
Check ILOM firmware versionFrom the ILOM web interface, navigate to the About or Firmware section to view the installed version. Alternatively, use the ILOM CLI command: version or show /system/firmware to retrieve the firmware version.Affected if The installed version is 3.0, 3.1, or 3.2
-
Verify web interface is enabledIn the ILOM web interface, navigate to ILOM Administration > Web Server or Settings > Services to confirm if the HTTP/HTTPS web interface is enabled. From CLI, check using: show /SP/web or show /SP/webSSL.Affected if The ILOM web interface (HTTP or HTTPS) is accessible and enabled
If the system runs Oracle Sun ILOM versions 3.0, 3.1, or 3.2 with the web interface enabled, the environment is affected by CVE-2015-4821.

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.
From vendor dataUpgrade ILOM firmware to patched versions beyond 3.2; if patching is not immediately feasible, restrict web interface access to trusted networks via firewall rules and disable ILOM web services if not required.
