Exploitation Summary

EIP tracks 2 public exploits for CVE-2023-36812. PoCs published by ErikWynter, Gal Goldstein, Daniel Abeles, Erik Wynter, including Metasploit module exploits/linux/http/opentsdb_key_cmd_injection.

AI-analyzed exploit summary This repository contains a Fortran-based exploit for CVE-2023-36812, a command injection vulnerability in OpenTSDB <= 2.4.1. The exploit leverages the Fortran http-client library to send malicious payloads to the target, achieving remote code execution.

Description

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 option`tsd.core.enable_ui = true` and remove the shell files `mygnuplot.bat` and `mygnuplot.sh`.
