Security readout for executives and security teams

This is an old Microsoft Excel information disclosure flaw. A specially crafted XML document could make affected Excel components resolve an external entity and read local files. The main business concern is exposure of files from endpoints or servers still running legacy Office components. Exposure is most likely on systems still using Excel 2003 SP3, Excel 2007 SP3, Excel 2010 SP1/SP2, Excel Viewer, or Office Compatibility Pack SP3, especially where untrusted documents are opened or processed. Treat this as a legacy software risk. Prioritize remediation where affected Office components remain in business workflows, document intake paths, or shared desktop images. Urgency increases if users routinely open external documents. Mitigation focus: Review and apply Microsoft guidance in MS13-073.; Remove or upgrade unsupported Excel, Excel Viewer, and Compatibility Pack installs.; Restrict opening untrusted XML or Office documents on legacy systems..
