Miggo AIRoot Cause Analysis

The vulnerability manifests in SSL connection handling where Undertow's pre-2.0.29 HTTPS implementation didn't properly manage resources during SSL handshakes. Key indicators:

  1. The mitigation through HTTP/2 suggests fundamental connection handling changes
  2. CWE-400 points to resource management in network I/O paths
  3. XNIO's SSL implementation (XnioSsl) is core to Undertow's low-level I/O
  4. HttpOpenListener is the entry point for HTTP(S) request processing While exact patch details are unavailable, these functions represent the most likely candidates based on the vulnerability pattern and Undertow architecture.
