Miggo AIRoot Cause Analysis

The vulnerability stems from improper XML parsing in the UDP discovery mechanism. The Talos report explicitly identifies getCandidateFromDatagramResponses() as the method handling datagram responses, and CWE-611 confirms this is an XXE vulnerability. The function's failure to configure XML parser security features (like disabling DTDs/external entities) directly enables the attack. The exploit PoC demonstrates malicious XML processing through this vector, confirming the function's role in the vulnerability.
