CVE-2024-38303
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 PowerEdge Platform, 14G Intel BIOS version(s) prior to 2.22.x, contains an Improper Input Validation vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Information disclosure.
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 confidenceDell PowerEdge 14G servers contain an improper input validation vulnerability in the BIOS firmware. A high-privileged local attacker could exploit this vulnerability to disclose sensitive information. The vulnerability affects BIOS versions prior to 2.22.x.

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 system modelLocate the Dell PowerEdge or Dell EMC storage model number on the server chassis label, or retrieve it via the iDRAC web interface under Server > Overview, or use the racadm command: racadm get System.System.1.ModelAffected if The model is not one of the following: Xc Core Xcxr2, Xc Core Xc940, Xc Core Xc740xd2, Xc Core Xc740xd, Xc Core Xc640, 6420, Storage Nx3340, or Storage Nx3240
-
Retrieve the current BIOS firmware versionAccess the iDRAC web interface and navigate to Maintenace > System Update > Firmware, or use the racadm command: racadm get BIOS.BiosVersionInfo.1.CurrentBIOSVersion. Alternatively, boot into BIOS setup and check the BIOS version on the main screen, or use Dell Update Package (DUP) from the OS: dupupd /s or omreport chassis biosAffected if Unable to retrieve a BIOS version number for comparison
-
Compare the installed version against affected thresholdsMatch your product model to its specific version threshold from the CVE: Xcxr2 and Xc740xd2 require version < 2.22.1 to be vulnerable; Xc940, Xc740xd, Xc640, 6420, Nx3340, and Nx3240 require version < 2.22.2 to be vulnerableAffected if The installed BIOS version is lower than the threshold for your specific model (less than 2.22.1 for Xcxr2/Xc740xd2, or less than 2.22.2 for all other affected models)
You are affected if you are running any of the listed Dell EMC XC Core or Storage NX models with a BIOS firmware version below the specified threshold for that product.

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 data2.22.12.22.2
Update Dell PowerEdge 14G BIOS to version 2.22.x or later to remediate the improper input validation vulnerability. This requires applying the Dell BIOS firmware update through the iDRAC interface or BIOS flash utility.
