OS Command Injection in Microsoft Windows (CVE-2025-68154)
Summary
OS command injection in Microsoft Windows (CVE-2025-68154). Successful exploitation can lead to full system takeover. Exploitable via drive.
Original description
The description as published by the source.
systeminformation is a System and OS information library for node.js. In versions prior to 5.27.14, the fsSize() function in systeminformation is vulnerable to OS command injection on Windows systems. The optional drive parameter is directly concatenated into a PowerShell command without sanitization, allowing arbitrary command execution when user-controlled input reaches this function. The actual exploitability depends on how applications use this function. If an application does not pass user-controlled input to fsSize(), it is not vulnerable. Version 5.27.14 contains a patch.
