Executive Technical Summary

Microsoft Internet Explorer 10 and 11 and Microsoft Edge have a type confusion issue in the Layout::MultiColumnBoxBuilder::HandleColumnBreakOnColumnSpanningElement function in mshtml.dll, which allows remote attackers to execute arbitrary code via vectors involving a crafted Cascading Style Sheets (CSS) token sequence and crafted JavaScript code that operates on a TH element.

Practical Defensive Validation (Authorized Only)

1. Use only isolated environments and systems you own or are explicitly authorized to test.
2. Snapshot infrastructure before validation and preserve baseline logs (EDR, SIEM, OS, app).
3. Use Microsoft Corporation / Internet Browser (versions: Internet Explorer 10 and 11 and Edge) in isolated VM snapshots (vulnerable vs patched) and compare process tree telemetry before/after updates.
4. Validate command-execution prevention policies (AppLocker/WDAC/EDR) with harmless test binaries only.
5. Create SIEM detections for suspicious parent-child chains, encoded command usage, and abnormal service creation.
