Windows Remote Access Connection Manager Information Disclosure Vulnerability

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

This is an information disclosure vulnerability in Windows Remote Access Connection Manager (rasman.dll). The vulnerability allows a local authenticated attacker to potentially access sensitive information that should be protected. The flaw exists in how the Remote Access Connection Manager handles certain operations or data, leading to unintended information exposure.

MitigationApply the Microsoft security update (KB5034441 or subsequent relevant patches) to address this vulnerability. As a defense-in-depth measure, ensure proper least-privilege principles are followed and restrict local account privileges where possible.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Windows version and build number
    Open Settings > System > About, or run 'winver' command, or run 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' in Command Prompt
    Affected if The Windows version and build number fall within any of the affected ranges listed (e.g., 10.0.10240.20651 or lower for 1507, 10.0.19045.4412 or lower for 10 22h2, etc.)
  2. Locate the rasman.dll file
    Find rasman.dll in the System32 folder, typically at C:\Windows\System32\rasman.dll
    Affected if The file exists on the system (it is a core Windows component)
  3. Check rasman.dll file version
    Right-click rasman.dll in File Explorer, go to Properties > Details, or run 'dir C:\Windows\System32\rasman.dll' and note the version timestamp, or use a PowerShell command like '[System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\Windows\System32\rasman.dll")'
    Affected if The file version is lower than the versions specified in the CVE for your Windows release (compare the Product Version or File Version field)
  4. Verify if security update is installed
    Open Settings > Windows Update > Update history, or run 'wmic qfe list' in Command Prompt to see installed hotfixes, looking for KB5034441 or subsequent relevant security patches
    Affected if The specific security update for CVE-2024-28900 (KB5034441 or later) is NOT listed among installed updates

You are affected if your Windows version/build falls within the affected ranges AND the rasman.dll file version is below the patched threshold AND the corresponding security update is not installed.
