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 PowerEdge Server BIOS contains a heap-based buffer overflow vulnerability. A local high privileged attacker could potentially exploit this vulnerability to write to otherwise unauthorized memory.

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 PowerEdge Server BIOS contains a heap-based buffer overflow vulnerability. A local attacker with high privileges could potentially exploit this vulnerability to write to otherwise unauthorized memory, potentially leading to code execution or system compromise.

MitigationApply the Dell BIOS/firmware update for the affected PowerEdge server models. This is typically obtained from Dell's support website and applied through the BIOS update utility or iDRAC lifecycle controller.

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 the exact PowerEdge server model
    Check the server label, iDRAC interface, or boot screen to confirm the specific model (R730, R730xd, R630, C4130, R930, M630, M630 pe Vrtx, or Fc630)
    Affected if model is not one of the eight listed affected models
  2. Access the BIOS firmware version
    Boot into BIOS setup screen, log into iDRAC web interface, or use Dell lifecycle controller to view current BIOS/firmware version
    Affected if unable to retrieve version information
  3. Compare installed version against affected thresholds
    Note the installed BIOS firmware version number and compare: for R730, R730xd, R630, C4130, M630, M630 pe Vrtx, Fc630 check if version is below 2.19.0; for R930 check if version is below 2.14.0
    Affected if firmware version is lower than the threshold for that specific model (2.19.0 for most models, 2.14.0 for R930)
  4. Verify high-privilege access exists
    Confirm the user has administrator or root-level privileges on the system (required for exploitation per CVE)
    Affected if attacker could obtain high-privilege access to the system

The environment is affected if the server is a listed PowerEdge model (R730, R730xd, R630, C4130, R930, M630, M630 pe Vrtx, Fc630) running BIOS firmware version below the model-specific threshold (2.19.0 or 2.14.0) and an untrusted user could gain high-privilege access.

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 2.14.0 / 2.19.0 or later
Fixed in 2.14.02.19.0
Interim mitigation

Apply the Dell BIOS/firmware update for the affected PowerEdge server models. This is typically obtained from Dell's support website and applied through the BIOS update utility or iDRAC lifecycle controller.

Recommended fix Moderate confidence

BIOS firmware version 2.19.0 or later (2.14.0 or later for PowerEdge R930)

  1. 1. Identify the specific PowerEdge model and current firmware version from the affected list (R730, R730xd, R630, C4130, R930, M630, Fc630)
  2. 2. Navigate to Dell's support website (www.dell.com) and locate the Drivers & Downloads section for your specific PowerEdge server model
  3. 3. Search for BIOS firmware updates - look for version 2.19.0 or higher (or version 2.14.0 or higher for PowerEdge R930)
  4. 4. Download the appropriate BIOS firmware update package for your server model
  5. 5. Review the firmware update README or release notes for any prerequisites or specific update instructions
  6. 6. Apply the firmware update using Dell's recommended method (iDRAC Lifecycle Controller, Dell Update Package, or BIOS flash utility)
  7. 7. Verify the firmware version has been successfully updated to the fixed release after completion
  8. 8. Reboot the server as required by the firmware update process
Caveat Firmware updates to BIOS typically require server downtime and should be tested in a non-production environment first; ensure to backup configuration and review compatibility requirements before applying
