Technical details
Before version 0.57.13, OpenHuman's scheduler fails to properly validate commands sent through external channels, allowing attackers to create cron jobs without approval. The command validation also permits leading environment variable assignments that can redirect allowed commands to malicious helper executables. An attacker with network access to a configured external channel can exploit this to gain persistent code execution with OpenHuman's privileges.
