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. Check Microsoft Excel version
    Open Excel, go to File > Help, and look for the version number under 'About Microsoft Excel'. Alternatively, run 'winword.exe /?' or check Add/Remove Programs for installed Microsoft Office components.
    Affected if The installed version is Excel 2007 or Excel 2010 (any sub-version).
  2. Check Office Compatibility Pack version
    Open Word or Excel and look for 'Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint file formats' in the installed programs list. Use Control Panel > Programs and Features to view installed software.
    Affected if Office Compatibility Pack is installed (any version).
  3. Determine if Office is part of an Office suite
    Check if Excel 2007/2010 was installed as part of a larger Microsoft Office suite (such as Office Professional Plus). In Programs and Features, look for the parent Office installation.
    Affected if Excel 2007 or 2010 is installed as a standalone application or as part of any Office suite version.
  4. Verify file opening behavior
    Attempt to open a test .xls or .xlsx file. Note whether files open directly in Excel without any sandbox or restricted view prompts.
    Affected if Documents open in full edit mode without any restricted viewing environment (this indicates potential exposure to malicious document payloads).

You are affected if you have Excel 2007, Excel 2010, or the Office Compatibility Pack installed, and you open untrusted Office documents without additional security filtering.
