Security readout for executives and security teams
Plain-English summary
CVE-2016-7193 is a Microsoft Office memory corruption flaw that can let an attacker run code if a crafted RTF document is opened or processed. It affects multiple legacy Word, Office, SharePoint Word Automation Services, Office Web Apps, and Office Online Server products. CISA lists it as known exploited, raising business urgency.
Executive priority
Prioritize remediation for legacy Office and SharePoint environments because this is known exploited and can lead to code execution after document interaction or processing.
Technical view
The vulnerability is described as arbitrary code execution through a crafted RTF document in Microsoft Word and related Office document-processing components. CVSS 3.1 is 7.8 with user interaction required and high confidentiality, integrity, and availability impact. Microsoft addressed it in MS16-121.
Likely exposure
Exposure is most likely where legacy Microsoft Office, Word Viewer, Office Compatibility Pack, SharePoint Word Automation Services, Office Web Apps, or Office Online Server installations remain unpatched or unsupported.

Researcher notes
Evidence supports RTF-triggered Microsoft Office memory corruption RCE with broad legacy product impact. No CWE is provided in the source bundle. Use MS16-121 for vendor patch mapping and CISA KEV for exploitation status.
Mitigation direction
- Apply Microsoft security bulletin MS16-121 updates where applicable.
- Retire or isolate unsupported Office and SharePoint document-processing components.
- Review Microsoft guidance for exact affected versions and update packages.
- Limit RTF handling in high-risk mail, upload, and document-processing workflows where feasible.
Validation and detection
- Inventory systems running affected Word, Office, SharePoint, Office Web Apps, and Office Online Server versions.
- Confirm MS16-121 or corresponding Microsoft updates are installed.
- Check whether unsupported affected products remain in production.
- Review email and document-processing controls for RTF attachment handling.
