CVE-2019-11177
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 · uneditedUnhandled exception in Intel(R) Baseboard Management Controller firmware may allow an unauthenticated user to potentially enable denial of service via network access.
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 confidenceAn unhandled exception vulnerability in Intel Baseboard Management Controller (BMC) firmware allows unauthenticated remote attackers to cause denial of service via network access. The BMC, which provides out-of-band management for servers, can be crashed by triggering the unhandled exception, resulting in loss of management capabilities.

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.
-
Confirm Intel BMC presenceAccess server hardware documentation, BIOS/UEFI settings, or check the BMC web interface at the BMC IP address (typically accessible via IPMI or Redfish). Intel BMCs are commonly found on Intel server platforms (e.g., Intel Server Boards, S2600 series).Affected if The system does not have an Intel Baseboard Management Controller firmware installed.
-
Check BMC firmware versionLog into the BMC web interface (or use IPMI command 'ipmitool -I lanplus -H <BMC_IP> -U admin -P password raw ...' or Redfish API) and navigate to the Firmware Information or System Information page. Record the BMC firmware version string.Affected if The installed BMC firmware version is lower than 2.18 (e.g., 2.16, 2.10, 1.x).
-
Verify BMC network accessibilityConfirm the BMC has an active network IP address and is reachable on the network. Check BMC network settings via the web interface under Network or LAN settings. Note whether the BMC management port is exposed to untrusted networks.Affected if The BMC is network-accessible (has an IP address on a LAN/VLAN) and the firmware version is below 2.18.
A system is affected if it runs Intel BMC firmware version below 2.18 and the BMC is network-accessible, allowing unauthenticated remote attackers to trigger the unhandled exception and cause a denial of service.

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 data2.18
Update Intel BMC firmware to the latest version provided by Intel for the affected platform. Restrict network access to BMC management interfaces using network segmentation and access controls.
