systeminformation is a System and OS information library for node.js. In versions prior to 5.30.8, a command injection vulnerability in the function allows an attacker to execute arbitrary OS commands via an unsanitized network interface parameter in the retry code path. In , the function sanitizes the parameter on the initial call (line 437). However, when the initial scan returns empty results, a retry (lines 440-441) calls with the **original unsanitized** value, which is passed directly to . Any application passing user-controlled input to is vulnerable to arbitrary command execution with
