OpenTSDB 2.4.1 unauthenticated command injection

Description

This module exploits an unauthenticated command injection vulnerability in the key parameter in OpenTSDB through 2.4.1 (CVE-2023-36812/CVE-2023-25826) in order to achieve unauthenticated remote code execution as the root user. The module first attempts to obtain the OpenTSDB version via the api. If the version is 2.4.1 or lower, the module performs additional checks to obtain the configured metrics and aggregators. It then randomly selects one metric and one aggregator and uses those to instruct the target server to plot a graph. As part of this request, the key parameter is set to the payload, which will then be executed by the target if the latter is vulnerable. This module has been successfully tested against OpenTSDB version 2.4.1.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
