Remote Code Execution in UpTrain via Malicious Checks Parameter

Executive Summary

UpTrain versions 0.7.1 and earlier have a remote code execution vulnerability in the /new_run endpoint. Attackers with access to UpTrain and valid authentication can exploit the checks and metadata parameters to execute arbitrary code on the host system, typically within the Docker container as per the documentation.

Detection Guidance

Detection requires checking for unauthorized code execution attempts via the /new_run endpoint. Monitor logs for suspicious POST requests to /new_run with unusual parameters like checks or metadata containing executable code. Inspect UpTrain container processes for unexpected child processes or network connections.

Impact Analysis

This vulnerability allows attackers to run arbitrary code on the host running UpTrain. If UpTrain is deployed in a Docker container, the attacker gains control within that container. This could lead to data breaches, unauthorized access, or disruption of services.
