CVE-2026-26280 WRITEUP HIGH WRITEUP
systeminformation <5.30.8 - Command Injection
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.
CVSS 8.4
CVE-2026-26318 WRITEUP HIGH WRITEUP
systeminformation <5.31.0 - Command Injection
systeminformation is a System and OS information library for node.js. Versions prior to 5.31.0 are vulnerable to command injection via unsanitized `locate` output in `versions()`. Version 5.31.0 fixes the issue.
CVSS 8.8
CVE-2020-26245 WRITEUP HIGH WRITEUP
systeminformation <4.30.5 - Command Injection
npm package systeminformation before version 4.30.5 is vulnerable to Prototype Pollution leading to Command Injection. The issue was fixed with a rewrite of shell sanitations to avoid prototyper pollution problems. The issue is fixed in version 4.30.5. If you cannot upgrade, be sure to check or sanitize service parameter strings that are passed to si.inetChecksite().
CVSS 8.1
CVE-2020-26274 WRITEUP MEDIUM WRITEUP
systeminformation <4.31.1 - Command Injection
In systeminformation (npm package) before version 4.31.1 there is a command injection vulnerability. The problem was fixed in version 4.31.1 with a shell string sanitation fix.
CVSS 6.4
CVE-2020-26300 WRITEUP MEDIUM WRITEUP
systeminformation <4.26.2 - Command Injection
systeminformation is an npm package that provides system and OS information library for node.js. In systeminformation before version 4.26.2 there is a command injection vulnerability. Problem was fixed in version 4.26.2 with a shell string sanitation fix.
CVSS 5.9
CVE-2020-7752 WRITEUP HIGH WRITEUP
Systeminformation < 4.27.11 - OS Command Injection
This affects the package systeminformation before 4.27.11. This package is vulnerable to Command Injection. The attacker can concatenate curl's parameters to overwrite Javascript files and then execute any OS commands.
CVSS 8.8
CVE-2020-7778 WRITEUP HIGH WRITEUP
Package Systeminformation <4.30.2 - Code Injection
This affects the package systeminformation before 4.30.2. The attacker can overwrite the properties and functions of an object, which can lead to executing OS commands.
CVSS 7.3
CVE-2021-21388 WRITEUP HIGH WRITEUP
Systeminformation < 5.6.4 - OS Command Injection
systeminformation is an open source system and OS information library for node.js. A command injection vulnerability has been discovered in versions of systeminformation prior to 5.6.4. The issue has been fixed with a parameter check on user input. Please upgrade to version >= 5.6.4. If you cannot upgrade, be sure to check or sanitize service parameters that are passed to si.inetLatency(), si.inetChecksite(), si.services(), si.processLoad() and other commands. Only allow strings, reject any arrays. String sanitation works as expected.
CVSS 8.9
CVE-2023-42810 WRITEUP CRITICAL WRITEUP
Systeminformation < 5.21.7 - Command Injection
systeminformation is a System Information Library for Node.JS. Versions 5.0.0 through 5.21.6 have a SSID Command Injection Vulnerability. The problem was fixed with a parameter check in version 5.21.7. As a workaround, check or sanitize parameter strings that are passed to `wifiConnections()`, `wifiNetworks()` (string only).
CVSS 9.8
CVE-2024-56334 WRITEUP HIGH WRITEUP
NPM Systeminformation < 5.23.7 - Code Injection
systeminformation is a System and OS information library for node.js. In affected versions SSIDs are not sanitized when before they are passed as a parameter to cmd.exe in the `getWindowsIEEE8021x` function. This means that malicious content in the SSID can be executed as OS commands. This vulnerability may enable an attacker, depending on how the package is used, to perform remote code execution or local privilege escalation. This issue has been addressed in version 5.23.7 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 7.8
CVE-2025-68154 WRITEUP HIGH WRITEUP
NPM Systeminformation < 5.27.14 - OS Command Injection
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.
