CVE-2026-116673 Details
Description
systeminformation is a System and OS information library for node.js. Prior to 5.33.14, the Linux networkStats(iface) implementation uses the caller-supplied interface value in an fs.existsSync() check and to build /sys/class/net/<iface> paths, including the operstate path, without verifying that it is a single interface-name segment or that the resolved path remains under /sys/class/net. An attacker who can control iface and create a directory containing symlinked statistics files can use parent-directory components and symlink traversal to make the API return the first line of a file readable by the Node.js process. The package does not expose a network endpoint, and the demonstrated scenario requires local filesystem setup. This issue is fixed in version 5.33.14.
A path traversal vulnerability has been identified in the systeminformation library for Node.js, specifically in versions prior to 5.33.14. The issue arises in the Linux implementation of the networkStats function, where the library constructs file paths based on user-supplied interface names without proper validation. This flaw allows an attacker to manipulate the interface name to traverse directories and access files outside the intended directory, potentially leading to unauthorized disclosure of information. The vulnerability requires local exploitation, as it involves creating a directory with symlinked statistics files that can be accessed by the Node.js process.
Users are advised to upgrade to systeminformation version 5.33.14 or later, where this vulnerability has been patched.
