GHSA-gf62-q6c8-6vxg
Picklescan versions before 0.0.33 fail to detect a specific malicious gadget in pickle __reduce__ methods, enabling attackers to execute arbitrary Python code by crafting malicious pickle files. This bypasses Picklescan's safety checks and can lead to supply-chain poisoning of shared model files.
AI Analysis
Technical Summary
The vulnerability in Picklescan prior to version 0.0.33 involves a failure to detect the numpy.f2py.crackfortran.getlincoef gadget used in pickle __reduce__ methods. This allows attackers to craft malicious pickle files that execute arbitrary Python code upon loading, bypassing the intended safety mechanisms of Picklescan. The issue is categorized under CWE-502 (Deserialization of Untrusted Data) and poses a high severity risk due to the potential for arbitrary code execution and supply-chain poisoning.
Potential Impact
Successful exploitation allows attackers to execute arbitrary Python code when malicious pickle files are loaded, bypassing Picklescan's safety checks. This can lead to supply-chain poisoning of shared model files, potentially compromising systems that rely on these models.
Mitigation Recommendations
A fix is available in Picklescan version 0.0.33 and later. Users should upgrade to version 0.0.33 or newer to mitigate this vulnerability. No other mitigation guidance is provided.
