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 installed Microsoft browsers
    Check Programs and Features or use 'Get-ItemProperty' in PowerShell for browser installations: Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' | Select DisplayName | Where-Object {$_.DisplayName -match 'Internet Explorer|Edge'}
    Affected if No Microsoft browsers are found, indicating the vulnerability does not apply to their environment
  2. Check Internet Explorer version
    Open Internet Explorer, go to Help > About Internet Explorer, or run 'ieversion' in command prompt, or check registry key: HKLM\SOFTWARE\Microsoft\Internet Explorer\Version
    Affected if The installed version is 9, 10, or 11, meaning the environment is running an affected browser version
  3. Confirm Microsoft Edge installation
    Check if Microsoft Edge is present on the system by looking for MicrosoftEdge.exe in C:\Windows\SystemApps\ or via PowerShell: Get-Process *Edge*
    Affected if Microsoft Edge is installed and executable, as all versions of Edge are affected by this CVE
  4. Determine if browsers are actively used
    Review browser usage logs, check default browser settings, or survey users to identify if IE9-11 or Edge are regularly launched
    Affected if Affected browsers (IE 9-10-11 or any Edge version) are in active use, creating a potential attack surface for XSS exploitation

The environment is affected if Internet Explorer versions 9, 10, or 11 or any version of Microsoft Edge is installed and actively used, as these browser versions contain the XSS vulnerability described in CVE-2016-7282.
