CVE-2023-24571
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 BIOS contains an Improper Input Validation vulnerability. A local authenticated malicious user with administrator privileges could potentially exploit this vulnerability to perform arbitrary code execution.
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 · moderate confidenceDell BIOS contains an improper input validation vulnerability that allows a local authenticated user with administrator privileges to potentially execute arbitrary code. The vulnerability exists in the BIOS firmware and stems from insufficient validation of input data, likely allowing a malicious actor to inject or manipulate code execution flow.

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 modelRun 'dmidecode -s system-product-name' or check the BIOS setup information screen to confirm the exact system modelAffected if The system is NOT a Dell Embedded Box PC 3000 - if it is a different Dell model, this CVE does not apply
-
Retrieve the BIOS firmware versionRun 'dmidecode -s bios-version' or access the BIOS setup and navigate to the BIOS/UEFI version information sectionAffected if The command fails to return version information or the system does not have a readable BIOS version string
-
Compare the installed version against the vulnerable rangeDocument the full version string returned (e.g., using dmidecode or BIOS setup) and compare numerically to version 1.18.0Affected if The installed BIOS version is below 1.18.0 (for example, 1.17.0, 1.16.0, etc.) - versions prior to 1.18.0 are affected by this vulnerability
-
Verify administrator privileges contextConfirm that exploitation requires a local authenticated user with administrator privileges - this is a local privilege escalation vulnerability, not remoteAffected if The vulnerability is only exploitable by an attacker who already has admin-level access to the system
You are affected if your system is a Dell Embedded Box PC 3000 running BIOS firmware version lower than 1.18.0, and an attacker already has local administrator access to exploit the input validation flaw.

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.
dbcve · scoped1.18.0
Apply the Dell BIOS firmware update provided by Dell through their support website or enterprise management tools. Verify the update is applicable to affected models and test in a controlled environment before broad deployment.
Firmware version 1.18.0 or later
- 1. Visit Dell's support website and search for 'Embedded Box PC 3000'
- 2. Navigate to the Drivers & Downloads section for this model
- 3. Download the BIOS update package version 1.18.0 or later
- 4. Extract the downloaded file and run the BIOS update utility as administrator
- 5. Follow the on-screen prompts to complete the firmware update
- 6. Restart the system to apply the BIOS changes
