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 · unedited
Dell Precision Tower BIOS contains an Improper Input Validation vulnerability. A locally authenticated malicious user with admin 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 confidence

Dell Precision Tower BIOS contains an improper input validation vulnerability. A locally authenticated malicious user with administrative privileges can exploit this vulnerability to perform arbitrary code execution. This is a firmware-level privilege escalation issue stemming from insufficient validation of input data within the BIOS.

MitigationApply the Dell BIOS firmware update for the Precision Tower systems. Restrict administrative access and monitor for suspicious local activity.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify your Dell Precision Tower model
    Check the system label on the case or run `systeminfo` (Windows) / `dmidecode -s system-product-name` (Linux) to confirm if the machine is a Precision 5820, 7820, or 7920
    Affected if The model is a Dell Precision 5820, 7820, or 7920 tower workstation
  2. Check the installed BIOS firmware version
    Access BIOS setup by pressing F2 at boot, or from the operating system run `dmidecode -s bios-version` (Linux) or use Dell Command | Configure via `dcu-cli /get biosinfo` (Windows)
    Affected if The BIOS version cannot be retrieved or is below the threshold for your model
  3. Compare the version from the previous step against these thresholds - note that versions are cumulative so the first number is major, second is minor (e.g., 2.30.0 < 2.32.0)
    Affected if Your BIOS version is below 2.32.0 (5820) or below 2.36.0 (7820/7920)
  4. Assess local access and privilege configuration
    Review which local users exist on the system and verify which ones have administrative or BIOS setup privileges - this vulnerability requires a locally authenticated user with admin rights
    Affected if Multiple local administrative accounts exist without multi-factor authentication on BIOS access and the system is physically accessible to untrusted local users

You are affected if your Dell Precision Tower workstation (5820/7820/7920) runs a BIOS firmware version below 2.32.0/2.36.0 respectively and permits local users with administrative privileges to access the system.

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 · scoped
Upgrade available Upgrade to 2.32.0 / 2.36.0 or later
Fixed in 2.32.02.36.0
Interim mitigation

Apply the Dell BIOS firmware update for the Precision Tower systems. Restrict administrative access and monitor for suspicious local activity.

Recommended fix High confidence

Precision 5820: BIOS version 2.32.0 or later | Precision 7820: BIOS version 2.36.0 or later | Precision 7920: BIOS version 2.36.0 or later

  1. Identify your specific Dell Precision model (5820, 7820, or 7920)
  2. Visit support.dell.com and enter your system's Service Tag to find available BIOS updates
  3. Download the BIOS firmware update package for your model
  4. Review the update instructions provided in the downloaded package
  5. Follow Dell's standard BIOS update procedure, which typically involves running the firmware update utility from Windows or using a bootable USB update method
  6. Restart the system after the update completes to ensure the new BIOS firmware is applied
Caveat BIOS updates carry inherent risk of system incompatibility; ensure power is maintained throughout the update process and do not interrupt the flashing procedure
