Miggo AIRoot Cause Analysis

The vulnerability description explicitly identifies the readObject method in DiskFileItem as the entry point. This method handles deserialization of file upload data but fails to properly sanitize NULL bytes in filenames during deserialization. This allows path traversal attacks by terminating filename validation checks early (via NULL byte injection). The dispute about responsibility doesn't change the technical reality that this method processes untrusted serialized data without adequate safeguards. The first patched version (7.0.39) confirms this was addressed in Tomcat's implementation.
