CVE-2016-4406
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 · uneditedA remote cross site scripting vulnerability was identified in HPE iLO 3 all version prior to v1.88 and HPE iLO 4 all versions prior to v2.44.
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 confidenceA remote cross-site scripting (XSS) vulnerability in the HPE iLO 3 web interface (versions prior to v1.88) and HPE iLO 4 (versions prior to v2.44) allows authenticated or unauthenticated attackers to inject malicious JavaScript code through unsanitized input fields in the management interface.

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 the iLO firmware version via web interfaceLog into the HPE iLO web interface and navigate to the Overview or Information page. Locate the firmware version field typically displayed under iLO Firmware Version or Firmware Revision.Affected if The displayed firmware version is below 1.88 for iLO 3 or below 2.44 for iLO 4
-
Identify the iLO firmware version via SSHConnect to the iLO using SSH (ssh <ilo-ip>), log in with administrative credentials, and run the command 'show /map1/firmware1' or 'info', which displays the firmware version details.Affected if The firmware version shown is below 1.88 for iLO 3 or below 2.44 for iLO 4
-
Identify the iLO firmware version via HP iLO RESTful InterfaceUse a tool like curl to query the HPE iLO RESTful API at https://<ilo-ip>/redfish/v1/Managers/1, which returns JSON containing the FirmwareVersion field.Affected if The FirmwareVersion value is below 1.88 for iLO 3 or below 2.44 for iLO 4
-
Check if the iLO web interface is exposed to networkVerify network accessibility of the iLO web interface by attempting to reach https://<ilo-ip> from an external network. Review firewall rules and network segmentation to determine if unauthenticated attackers can reach the management interface.Affected if The iLO web interface is reachable from untrusted networks and the firmware version is below the fixed releases
You are affected if your HPE iLO 3 firmware is version 1.87 or lower, or your HPE iLO 4 firmware is version 2.43 or lower, particularly if the web 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.
From vendor data1.882.44
Upgrade HPE iLO 3 firmware to version 1.88 or later, and HPE iLO 4 firmware to version 2.44 or later to resolve the XSS vulnerability.
