Summary
The systeminformation npm package before 5.33.14 is affected. The Linux networkStats() function does not validate the caller-supplied interface name, which allows path traversal through symlinks (CWE-22). A local user with low privileges who controls that value and can create symlinked statistics files can make the API return the first line of a file readable by the Node.js process.

Description from the CNA
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.
