Prior to 1.1.2, src/App/PropertyPythonObject.cpp in PropertyPythonObject::Restore() passes the attacker-controlled module attribute from serialized PropertyPythonObject XML directly to PyImport_ImportModule() while restoring a crafted FCStd document, which executes module-level Python code, and the legacy pickle branch also imports an attacker-controlled module and invokes its class constructor through PyObject_CallObject(). This issue is fixed in version 1.1.2.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":51,"depthScoreParts":{"impact":38.5,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[]}
