Miggo AIRoot Cause Analysis

The vulnerability documentation explicitly identifies XmlRpcResponseParser.addResult as the entry point for untrusted deserialization. Code analysis shows it processes the 'faultCause' parameter by deserializing its contents via ObjectInputStream, which is inherently unsafe when processing untrusted data. Multiple independent sources (CVE description, Red Hat advisories, and Apache mailing list threads) confirm this as the root cause. The presence of this deserialization pattern without proper safeguards directly enables the documented RCE vulnerability.
