What it means

Excel workbook combines abnormal Forms.CommandButton OBJ record IDs with XLM/VBA auto-execution context.

Why it fires

CVE-2009-0557 is the Microsoft Excel Object Record Corruption vulnerability. This detector keys on a narrow workbook structure: multiple Forms.CommandButton OBJ records with abnormal object-id gaps, several XLM macro sheets, and a VBA project. The auto-exec context is required so normal spreadsheets with form controls do not receive CVE attribution.
