CVE-2014-6319
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 · uneditedOutlook Web App (OWA) in Microsoft Exchange Server 2007 SP3, 2010 SP3, and 2013 SP1 and Cumulative Update 6 does not properly validate tokens in requests, which allows remote attackers to spoof the origin of e-mail messages via unspecified vectors, aka "Outlook Web App Token Spoofing 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 confidenceThe Outlook Web App in Microsoft Exchange Server 2007 SP3, 2010 SP3, and 2013 SP1/CU6 contains a token validation flaw that allows remote attackers to spoof the origin of e-mail messages by submitting specially crafted requests with improperly validated tokens.

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 Exchange Server versionRun Get-ExchangeServer | Select-Object Name,Admindisplayversion,ServerRole in Exchange Management Shell, or check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersVersion in the registryAffected if The version shown is Exchange Server 2007, 2010, or 2013 (specifically SP1 or CU6 for 2013)
-
Confirm OWA is enabledRun Get-OwaVirtualDirectory in Exchange Management Shell to list OWA virtual directoriesAffected if Any OWA virtual directory exists and is enabled (the vulnerability exists in OWA regardless of whether external access is configured)
-
Check Exchange build numberRun Get-ExchangeServer | Format-List Name, *Version* to get the exact build number, then compare against Microsoft's published build tables for Exchange 2007, 2010, and 2013Affected if The build corresponds to an unpatched release of Exchange 2007, Exchange 2010, or Exchange 2013 SP1/CU6
If OWA is enabled on an unpatched Exchange Server 2007, 2010, or 2013 SP1/CU6 installation, the environment is vulnerable to token validation bypass in OWA.

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 Microsoft security updates for the affected Exchange Server versions or upgrade to a patched Cumulative Update to address the token validation vulnerability in OWA.
