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 installed Internet Explorer versionOpen Internet Explorer, click Help > About Internet Explorer to view the version number, or check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\VersionAffected if The installed version is 8, 9, 10, or 11
-
Check for Microsoft Edge installationVerify if Microsoft Edge is installed by checking for the executable at C:\Windows\SystemApps\Microsoft.Windows.Edge_cw5n1h2txyewy\MicrosoftEdge.exe, or look in the Start MenuAffected if Microsoft Edge is present on the system (all versions are affected)
-
Verify if browser is in useCheck whether Internet Explorer or Edge is enabled and accessible on the system by attempting to launch the browser or checking registry key HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternetAffected if Either Internet Explorer 8-11 or Microsoft Edge is installed and can be launched
-
Check for MS15-124 security updateOpen Control Panel > Programs and Features > View installed updates, or run 'wmic qfe get hotfixid' command in CMD, and search for KB3124275 or KB3124900Affected if The MS15-124 security update (KB3124275 or KB3124900) is NOT installed - the system is vulnerable if unpatched
A system is affected if Internet Explorer version 8, 9, 10, or 11 OR Microsoft Edge is installed, and the MS15-124 security update (KB3124275/KB3124900) has not been applied.

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 (MS15-124) to all affected systems running Internet Explorer 8-11 and Microsoft Edge. Until patches are applied, restrict user access to untrusted websites and enable Enhanced Protected Mode in Internet Explorer.
