The yrange value is written to a gnuplot file in the /tmp directory. This file is then executed via the mygnuplot.sh shell script. (tsd/GraphHandler.java attempted to prevent command injections by blocking backticks but this is insufficient.)","published":"2020-12-16T08:15:13.560Z","modified":"2026-07-08T23:35:25.498528Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":3,"affectedPackages":[{"ecosystem":"Maven","name":"net.opentsdb:opentsdb","fixedVersion":null}],"fix":null,"references":[{"type":"REPORT","url":"https://github.com/OpenTSDB/opentsdb/issues/2051"},{"type":"EVIDENCE","url":"http://packetstormsecurity.com/files/170331/OpenTSDB-2.4.0-Command-Injection.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T23:35:25.498528Z"}}
