CVE-2011-1989 – Microsoft Office Excel Conditional Expression Ptg Type Confusion Vulnerability

https://notcve.org/view.php?id=CVE-2011-1989

Microsoft Excel 2003 SP3 and 2007 SP2; Excel in Office 2007 SP2; Excel 2010 Gold and SP1; Excel in Office 2010 Gold and SP1; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; Excel Viewer SP2; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2; Excel Services on Office SharePoint Server 2007 SP2; Excel Services on Office SharePoint Server 2010 Gold and SP1; and Excel Web App 2010 Gold and SP1 do not properly parse conditional expressions associated with formatting requirements, which allows remote attackers to execute arbitrary code via a crafted spreadsheet, aka "Excel Conditional Expression Parsing Vulnerability." Microsoft Excel 2003 Service Pack 3 y Service Pack 2 de 2007; Excel en Office 2007 SP2, Excel 2010 Service Pack 1 Gold y SP1; Excel en Office 2010 Service Pack 1 Gold y SP1; Office 2004, 2008 y 2011 para Mac; Open XML File Format Converter para Mac; Excel Viewer Service Pack 2; Paquete de compatibilidad de Office para Word, Excel y PowerPoint 2007 Service Pack 2, Servicios de Excel en Office SharePoint Server 2007 SP2, Servicios de Excel en Office SharePoint Server 2010 Gold y SP1, y Excel Web Access 2010 Gold y SP1 no analizan correctamente las expresiones condicionales asociadas con requisitos de formato, lo que permite a atacantes remotos ejecutar código de su elección a través de una hoja de cálculo debidamente modificada. Es un problema también conocido como "Vulnerabilidad de análisis de expresiones condicionales de Excel". This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Office Excel. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within how the application parses expressions used for determining formatting requirements. • http://www.us-cert.gov/cas/techalerts/TA11-256A.html https://docs.microsoft.com/en-us/security-updates/securitybulletins/2011/ms11-072 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A12974 • CWE-20: Improper Input Validation •
