Miggo AIRoot Cause AnalysisThe vulnerability (CWE-20) explicitly involves improper Host header validation. The CVE description and NiFi security notes indicate the fix added header sanitization/whitelist checks. Key functions would be those handling proxy headers (X-Forwarded-Host/X-ProxyContextPath) and raw Host header retrieval, as these are the entry points for the malicious input. WebUtils.getProxiedHosts() is a known utility for proxy header processing in NiFi, and JettyServer's request handling would directly access headers. These functions would appear in runtime traces when processing HTTP requests with malicious Host headers, making them primary candidates for detection.
