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
Use of uninitialized resource in Windows Remote Access Connection Manager allows an authorized attacker to elevate privileges locally.

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 confidence

A local privilege escalation vulnerability exists in Windows Remote Access Connection Manager (RasMan) due to the use of an uninitialized resource. An authorized attacker with local access can exploit this to elevate their privileges to SYSTEM level, achieving full control over the affected Windows system.

MitigationApply the Microsoft security update addressing CVE-2025-62472 through Windows Update or the relevant KB patch. Verify the Remote Access Connection Manager service functions normally after patching.

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. Check Windows version build number
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Version"' to obtain the full build number (e.g., 10.0.19045.xxxx)
    Affected if The build number falls below the threshold for your Windows release (e.g., < 10.0.19045.6691 for Windows 10 22h2)
  2. Identify exact Windows release
    Run 'winver' to confirm whether the system is Windows 10 1607, 1809, 21h2, 22h2, Windows 11 23h2, 24h2, 25h2, or Windows Server 2008 R2
    Affected if The system is any affected version listed in the CVE (Windows 10 1607/1809/21h2/22h2, Windows 11 23h2/24h2/25h2, or Windows Server 2008 R2)
  3. Verify RasMan service presence
    Run 'Get-Service -Name RasMan' in PowerShell or 'sc query RasMan' to check if the Remote Access Connection Manager service exists
    Affected if The RasMan service is present on the system (this is the vulnerable component)
  4. Confirm service status
    Run 'Get-Service -Name RasMan | Select-Object Status' to check if the service is running
    Affected if The RasMan service is running (required for exploitation, though the vulnerability exists in the service binary regardless of state)

You are affected if your Windows version matches one of the affected releases AND the build number is below the specified threshold for that release, AND the RasMan service is present on 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.

  1. Identify the current Windows build version by running 'winver' or 'systeminfo' in Command Prompt
  2. Open Windows Settings > Update & Security > Windows Update
  3. Click 'Check for updates' to download and install the latest cumulative update containing the security fix
  4. If automatic updates are unavailable, manually download the specific KB update from the Microsoft Update Catalog (catalog.update.microsoft.com) matching your Windows version
  5. After installing the update, restart the system to apply the changes
  6. Verify the fix by confirming the build number matches or exceeds the fixed version for your Windows release
Caveat Windows Server 2008 R2 is end-of-life; upgrade to a supported Windows Server version for continued security support
