Remote code execution via undisclosed input handling
Published Apr 15, 2022 · Updated Jan 2, 2025
Remote code execution in Microsoft DiskUsage.exe on Windows 11 21H2 and Windows Server 2022 allows remote attackers to execute code. Microsoft has not disclosed the vulnerable code path or the incorrect operation DiskUsage.exe performs on attacker-controlled input. Exploitation requires no privileges but requires user interaction and high attack complexity, with successful exploitation compromising data and service availability.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.0.0 <10.0.22000.613
