  "title": "jupyterlab: systeminformation is a System and OS information library for node.js",
  "description": "systeminformation is a System and OS information library for node.js. In versions prior to 5.30.8, a command injection vulnerability in the \u0060wifiNetworks()\u0060 function allows an attacker to execute arbitrary OS commands via an unsanitized network interface parameter in the retry code path. In \u0060lib/wifi.js\u0060, the \u0060wifiNetworks()\u0060 function sanitizes the \u0060iface\u0060 parameter on the initial call (line 437). However, when the initial scan returns empty results, a \u0060setTimeout\u0060 retry (lines 440-441) calls \u0060getWifiNetworkListIw(iface)\u0060 with the **original unsanitized** \u0060iface\u0060 value, which is passed directly to \u0060execSync(\u0027iwlist ${iface} scan\u0027)\u0060. Any application passing user-controlled input to \u0060si.wifiNetworks()\u0060 is vulnerable to arbitrary command execution with the privileges of the Node.js process. Version 5.30.8 fixes the issue.",
