NASA cFS Pickle pickle.load deserialization
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.
