Published Sep 12, 2023 · Updated Oct 30, 2025

Command injection in Microsoft Windows MSHTML Platform allows attackers to execute commands after required user interaction. Microsoft maps the flaw to CWE-77 but has not disclosed the affected code locus or how special command elements evade neutralization. Exploitation requires local delivery, high complexity, and user interaction but no prior privileges; successful attacks can compromise confidentiality, integrity, and availability.
