CVE-2026-5473 Details
Description
A vulnerability has been found in NASA cFS up to 7.0.0. The impacted element is the function pickle.load of the component Pickle Module. Such manipulation leads to deserialization. The attack needs to be performed locally. The attack requires a high level of complexity. The exploitability is regarded as difficult. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A deserialization vulnerability has been identified in NASA's Core Flight System (cFS) version 7.0.0. The issue arises from the use of Python's pickle module to load command and parameter definition files without proper integrity verification. This flaw allows for arbitrary code execution, as the pickle module can execute code during deserialization via the __reduce__ protocol. An attacker who can modify any .pickle file in the 'CommandFiles' or 'ParameterFiles' directories can execute arbitrary OS commands when the corresponding file is loaded in the cFS Ground System GUI.
No known mitigation is available.
