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

CVE-2026-50289

High
8.7/10

Summary

On Linux, `systeminformation`'s `networkInterfaces()` is vulnerable to OS Command Injection through the Debian/Ubuntu `interfaces(5)` `source` directive. While collecting per-interface DHCP state, the library reads `/etc/network/interfaces` and, for every `source <path>` line it encounters, extracts the path token *from the file content* and interpolates it unquoted into a shell command string that is run via `execSync()`. A `source` line whose path contains shell metacharacters executes arbitrary commands with the privileges of the calling Node.js process. This issue affects Systeminformation versions prior to 5.31.7.

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'.
