4Description
Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python's cProfile module as unsafe. Because of this, a malicious pickle that uses cProfile.run() is classified as SUSPICIOUS instead of OVERTLY_MALICIOUS. If a user relies on Fickling's output to decide whether a pickle is safe to deserialize, this misclassification can lead them to execute attacker-controlled code on their system. This affects any workflow or product that uses Fickling as a security gate for pickle deserialization. This issue has been patched in version 0.1.7.
Analysis
Fickling's static analyzer through version 0.1.6 fails to properly classify the cProfile module as unsafe during pickle analysis, causing malicious pickles leveraging cProfile.run() to be marked as SUSPICIOUS rather than OVERTLY_MALICIOUS. Organizations using Fickling as a security gate for deserialization decisions may be deceived into executing attacker-controlled code. …
