Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVE-2026-44724

Severity Low
Score 0/10

Summary

On Linux, systeminformation is vulnerable to command injection in `networkInterfaces()` when an active `NetworkManager` connection profile name contains shell metacharacters. This is not caused by a caller passing attacker-controlled arguments into `networkInterfaces()`. The vulnerable value is obtained internally from real `nmcli` device status output. The library sanitizes the network interface name before using it in shell commands, but it does not apply equivalent sanitization to the parsed `NetworkManager` connection profile name. That `unsanitized connectionName` is then interpolated into three shell command strings executed through `execSync()`. This issue affects systeminformation versions 4.17.0 through 5.31.5.

CWE-78 - OS Command Injection

The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
