EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 16.5%, top 3% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

OpenTSDB is a open source, distributed, scalable Time Series Database (TSDB). OpenTSDB is vulnerable to Remote Code Execution vulnerability by writing user-controlled input to Gnuplot configuration file and running Gnuplot with the generated configuration. This issue has been patched in commit 07c4641471c and further refined in commit fa88d3e4b. These patches are available in the 2.4.2 release. Users are advised to upgrade. User unable to upgrade may disable Gunuplot via the config optiontsd.core.enable_ui = true and remove the shell files mygnuplot.bat and mygnuplot.sh.
