Command injection yields full C/I/A; library executes locally (AV:L), attacker can force the empty-scan retry reliably (AC:L), and reaching the sink assumes some application-level privilege (PR:L).

Ecosystem-wide dependent count for version 5.30.8.
DescriptionNVD
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.
AnalysisAI
Command injection in the systeminformation Node.js library (versions prior to 5.30.8) lets attackers run arbitrary OS commands on Linux hosts through the wifiNetworks() function. While the iface argument is sanitized on the first call, the setTimeout retry path (triggered when the initial scan returns no results) re-invokes getWifiNetworkListIw() with the original unsanitized value, which reaches execSync('iwlist <iface> scan'). Any application that forwards user-controlled input to si.wifiNetworks() can be coerced into executing commands with the Node.js process privileges; publicly available exploit code exists, though EPSS risk is low (0.08%, 24th percentile) and it is not on the CISA KEV list.
