Elevated risk66th percentile - higher than 66% of all known CVEs
Summary
The systeminformation library for Node.js contains a command injection vulnerability in the `wifiNetworks()` function. In the retry code path, the `iface` parameter is not sanitized, allowing an attacker to execute arbitrary OS commands.
Risk Assessment
The organization is at risk of remote code execution with Node.js process privileges, potentially leading to server compromise, data theft, or further attack escalation.
Recommendation
Immediately update the systeminformation library to version 5.30.8 or later. Additionally, avoid passing unsanitized user input to the `wifiNetworks()` function.
Other vulnerabilities in systeminformation
See all- CVE-2026-50289High
The systeminformation library for Node.js before version 5.31.7 is vulnerable to OS command injection via the networkInterfaces() function on Linux. The issue stems from improper handling of the source directive in network configuration files, allowing arbitrary command execution.
- CVE-2026-44724High
The systeminformation library for Node.js versions 4.17.0 to 5.31.5 is vulnerable to command injection in the networkInterfaces() function on Linux. This occurs when an active NetworkManager connection profile name contains shell metacharacters that are not properly sanitized before being used in shell commands.
- CVE-2026-26318High
The systeminformation library for Node.js prior to version 5.31.0 is vulnerable to command injection via unsanitized `locate` output in the `versions()` function. An attacker can exploit this flaw to execute arbitrary system commands.
Original NVD description (English source)
systeminformation is a System and OS information library for node.js. In versions prior to 5.30.8, a command injection vulnerability in the `wifiNetworks()` function allows an attacker to execute arbitrary OS commands via an unsanitized network interface parameter in the retry code path. In `lib/wifi.js`, the `wifiNetworks()` function sanitizes the `iface` parameter on the initial call (line 437). However, when the initial scan returns empty results, a `setTimeout` retry (lines 440-441) calls `getWifiNetworkListIw(iface)` with the **original unsanitized** `iface` value, which is passed directly to `execSync('iwlist ${iface} scan')`. Any application passing user-controlled input to `si.wifiNetworks()` is vulnerable to arbitrary command execution with the privileges of the Node.js process. Version 5.30.8 fixes the issue.
