AI-suggested
- Immediately upgrade the systeminformation library to version 5.27.14 or later where the vulnerability is patched.
- Conduct a thorough code review to identify all usages of the fsSize() function and verify that no user-controlled input is passed to the 'drive' parameter.
- Implement strict input validation and sanitization for any parameters that influence system commands, especially those passed to PowerShell or shell commands.
- Employ application-level security controls such as Web Application Firewalls (WAFs) to detect and block suspicious command injection patterns.
- Restrict the privileges of Node.js processes to minimize impact if exploitation occurs, following the principle of least privilege.
- Monitor logs for unusual PowerShell command executions or unexpected systeminformation library calls.
- Educate developers about secure coding practices related to command execution and parameter handling.
- If upgrading immediately is not possible, consider isolating affected applications or disabling features that invoke fsSize() with external input until patched.
Description
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.
