Local command execution via unsafe YAML loading
Published May 21, 2024 · Updated Aug 2, 2024
Command execution in NASA AMMOS AIT-Core 2.5.2 allows local users to run arbitrary commands through a crafted YAML file. The telemetry module loads definitions with PyYAML 5.3.1, whose unsafe loader constructs attacker-selected Python objects instead of limiting input to basic data types. Exploitation requires write access to an AIT-Core YAML file or configuration that points to one, and commands run with the AIT-Core process's privileges.
