CVE-2024-25942
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 Server BIOS contains an Improper SMM communication buffer verification vulnerability. A physical high privileged attacker could potentially exploit this vulnerability leading to arbitrary writes to SMRAM.
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 Server BIOS contains an improper System Management Mode (SMM) communication buffer verification vulnerability. A physical attacker with high privileges can exploit this to perform arbitrary writes to SMRAM (System Management RAM), potentially executing code in the highly privileged SMM environment and bypassing security controls.

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 PowerEdge server modelCheck the server model number via the Dell iDRAC web interface, BIOS boot screen, or physical chassis labelAffected if The server is one of: R730, R730xd, R630, C4130, R930, M630, M630 (pe Vrtx), or Fc630
-
Check the installed BIOS/firmware versionAccess the BIOS version through iDRAC Lifecycle Controller under 'Firmware' or run 'racadm get BIOS.SysInformation' via racadm tool if iDRAC is availableAffected if The firmware version is below 2.19.0 for R730/R730xd/R630/C4130/M630/M630(pe Vrtx)/Fc630, or below 2.14.0 for R930
-
Compare version against affected rangesReview the version number displayed in iDRAC or Lifecycle Controller against the vulnerability thresholdsAffected if Version is less than 2.19.0 (or 2.14.0 for R930) - indicating the vulnerable BIOS/firmware is installed
-
Verify physical access and privilege levelConfirm who has physical access to the server and which accounts have high privileges (Administrator/root) on iDRACAffected if Multiple untrusted individuals have physical access or high-privilege iDRAC accounts exist beyond necessary personnel
You are affected if you run any of the listed PowerEdge models with BIOS/firmware version below 2.19.0 (or 2.14.0 for R930) and an untrusted person could gain physical access or high-privilege administrative rights.

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 data2.14.02.19.0
Apply the Dell BIOS/firmware update for affected PowerEdge servers. Since this requires physical access and high privileges, also enforce physical security controls and limit administrative access to only necessary personnel.
