CVE-2020-35476: Opentsdb

Critical severity, CVSS 9.8. EPSS: 85.3% chance of exploitation in the next 30 days.

A remote code execution vulnerability occurs in OpenTSDB through 2.4.0 via command injection in the yrange parameter. 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.)

Affected products

• Opentsdb Opentsdb: up to and including 2.4.0
