CVE-2023-25949
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 · uneditedUncontrolled resource consumption in some Intel(R) Aptio* V UEFI Firmware Integrator Tools may allow an authenticated user to potentially enable denial of service via local access.
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 confidenceCVE-2023-25949 is an uncontrolled resource consumption vulnerability in Intel Aptio V UEFI Firmware Integrator Tools. An authenticated local user can exploit this to cause denial of service by exhausting system resources.

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.
-
Verify Intel Aptio V UEFI Firmware Integrator Tools is installedCheck for the presence of the Intel Aptio V UEFI Firmware Integrator Tools software on the system. This may be found in Program Files, Program Files (x86), or a dedicated Intel tooling directory. Look for executables or components named 'AptioV' or 'FirmwareIntegrator' or check Windows Programs and Features for installed Intel firmware tools.Affected if The software is present on the system
-
Identify the installed version of the firmware integrator toolLocate the main executable or DLL for the Intel Aptio V UEFI Firmware Integrator Tools. Right-click the executable, select Properties, and check the Version tab. Alternatively, run the executable with a version flag if available (such as -v, --version, or /version), or check any README or version info files included with the tool.Affected if The version cannot be determined or the tool is not found
-
Compare installed version against affected versionsCompare the identified version string exactly to the affected versions: 5.27.03.0003 and 5.27.06.0017. Ensure an exact match comparison, as the vulnerability applies only to these specific versions.Affected if The installed version is exactly 5.27.03.0003 or exactly 5.27.06.0017
-
Verify local user authentication contextDetermine whether untrusted or unauthenticated local users have access to the system where this tool is installed. The vulnerability requires an authenticated local user to trigger the resource exhaustion. Check system permissions and user account controls.Affected if Untrusted or anonymous local users can access the system and the affected tool is installed
The system is affected only if Intel Aptio V UEFI Firmware Integrator Tools version 5.27.03.0003 or 5.27.06.0017 is installed AND untrusted local users could potentially access and execute the tool.

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 dataApply Intel-provided firmware updates for Aptio V or restrict local access to trusted, authenticated users only to mitigate this DoS vector.
