CyberRota Analysis
AI-GeneratedMONAI versions prior to 1.6.0 are susceptible to OS command injection through the nnUNetV2Runner component, where user-controlled inputs from YAML configuration files and command-line arguments are improperly handled. This vulnerability allows attackers to execute arbitrary commands with the privileges of the user running the training or validation jobs, posing a significant risk to systems running affected versions on both Windows and Linux. Organizations utilizing MONAI for machine learning tasks should prioritize patching to mitigate potential exploitation.

Original NVD Description
MONAI before 1.6.0 is vulnerable to OS command injection in the nnUNetV2Runner component (monai.apps.nnunet.nnunetv2_runner). User-controlled values taken from the YAML configuration file (notably dataset_name_or_id) and from CLI/kwargs arguments are concatenated into a command string without quoting or validation and then passed to subprocess with shell=True, so shell metacharacters (e.g., ';' on Linux, '&' on Windows) are interpreted. If a victim loads and processes a crafted configuration file — for example by instantiating nnUNetV2Runner with the malicious YAML and invoking a training/validation job such as train_single_model() — arbitrary commands are executed with the privileges of the user running the job.
