CVE-2016-0190
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 · uneditedVolume Manager Driver in Microsoft Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT 8.1 does not properly check whether RemoteFX RDP USB disk accesses originate from the user who mounted a disk, which allows local users to read arbitrary files on these disks via RemoteFX requests, aka "Remote Desktop Protocol Drive Redirection 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 · high confidenceA vulnerability in the Volume Manager Driver in Windows 8.1, Server 2012/R2, and RT 8.1 fails to validate that RemoteFX RDP USB disk redirection requests originate from the same user who originally mounted the disk. This allows local authenticated users to read arbitrary files from mounted USB disks via RemoteFX requests, enabling unauthorized information disclosure.

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.
-
Identify Windows versionRun 'winver' or check System Properties to determine the exact Windows version and build numberAffected if The system is running Windows 8.1, Windows RT 8.1, Windows Server 2012, or Windows Server 2012 R2 (any version)
-
Check if RemoteFX USB redirection is availableVerify RemoteFX USB Redirection feature is installed: open Remote Desktop Session Host Configuration > check RDP connection properties > Client Settings tab, or inspect the registry key HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\fEnableRemoteFXUSBAffected if RemoteFX USB redirection is present or can be enabled on the system
-
Determine if RemoteFX USB redirection is enabledCheck Group Policy settings at Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Session Environment > Enable RemoteFX USB Device Redirection, or check the registry value at HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\fEnableRemoteFXUSB (1 = enabled)Affected if RemoteFX USB redirection is currently enabled on the system
-
Verify USB disk redirection session behaviorReview RDP connection logs or terminal services logs for USB device redirection activity during RemoteFX sessionsAffected if USB disk redirection through RemoteFX has been used on the system
A system is affected if it runs Windows 8.1, Server 2012/R2, or RT 8.1 AND has RemoteFX USB redirection enabled, allowing any local authenticated user to access files on USB disks mounted by other users.

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 the Microsoft security update for CVE-2016-0190. As a compensating control, consider disabling RemoteFX USB redirection via Group Policy or RDP settings if not required for business operations.
