A critical security flaw in Jupyter notebook deployments lets attackers exploit misconfigurations. By running with root privileges and disabled authentication, Jupyter servers expose their REST API to unauthorized access. This flaw allows attackers to create terminal sessions that inherit root privileges, enabling complete system control.
Researchers found that local network access to a vulnerable Jupyter server permits attackers to create a terminal session via an HTTP POST request to the /api/terminals endpoint. This access leads to executing arbitrary commands and potentially compromising sensitive data. Recommendations to prevent such vulnerabilities include never running Jupyter services as root, enabling authentication tokens, and considering the disabling of terminal access.
Organizations should also employ monitoring best practices to track the usage of the terminal API and monitor for unusual connection attempts from Jupyter processes. This situation underscores the dangers of overlooking default configurations and the importance of implementing fundamental security measures.
