CVE-2018-15776
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 · uneditedDell EMC iDRAC7/iDRAC8 versions prior to 2.61.60.60 contain an improper error handling vulnerability. An unauthenticated attacker with physical access to the system could potentially exploit this vulnerability to get access to the u-boot shell.
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 confidenceThis is an improper error handling vulnerability in Dell EMC iDRAC7 and iDRAC8 firmware versions prior to 2.61.60.60. An unauthenticated attacker with physical access to the server can exploit improper error handling to gain access to the u-boot shell, a bootloader environment that provides low-level system access.

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 iDRAC modelAccess the iDRAC web interface, use racadm command 'racadm get iDRAC.Info', or check during server boot to confirm whether the device is iDRAC7 or iDRAC8Affected if The device is not iDRAC7 or iDRAC8 (other models are not affected by this CVE)
-
Check iDRAC firmware versionVia iDRAC web interface in the Overview > iDRAC Settings > Firmware page, or run 'racadm getversion' command line, or view during POST boot screenAffected if The firmware version is less than 2.61.60.60 (versions prior to this are affected)
-
Verify physical access exposureAssess whether unauthorized individuals can physically access the server housing the iDRACAffected if Physical access is possible for unauthenticated attackers - this is required for exploitation
You are affected if you have an iDRAC7 or iDRAC8 with firmware version below 2.61.60.60 AND physical access to the server is not restricted

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 data2.61.60.60
Update iDRAC firmware to version 2.61.60.60 or later. As a defense-in-depth measure, restrict physical access to servers hosting vulnerable iDRAC devices.
