{"id":"DEBIAN-CVE-2026-50289","details":"systeminformation is a System and OS information library for node.js. Prior to 5.31.7, networkInterfaces() on Linux is vulnerable to OS command injection through the Debian/Ubuntu interfaces(5) source directive because lib/network.js checkLinuxDCHPInterfaces() reads /etc/network/interfaces, extracts a source \u003cpath\u003e token from file content, and interpolates it unquoted into cat ${file} 2\u003e /dev/null | grep 'iface\\|source' executed by execSync(cmd, util.execOptsLinux), allowing a path containing shell metacharacters to execute commands in any process that calls networkInterfaces(), including via getStaticData() and getAllData(). This issue is fixed in version 5.31.7.","modified":"2026-08-27T23:06:12.294096107Z","published":"2026-07-17T20:17:24.857Z","upstream":["CVE-2026-50289"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-50289"}],"affected":[{"package":{"name":"node-systeminformation","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-systeminformation?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.31.7-1"}]}],"versions":["5.31.6-1","5.31.6-2","5.31.6-3","5.31.6-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-50289.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
