Lo script fornisce un verdetto intelligente basato sui segnali di enforcement conformi a RFC 9113:
Server sends GOAWAY with ENHANCE_YOUR_CALM (0xb) error code
Classification: NOT VULNERABLE — protocol-layer enforcement is active
Meaning: HTTP/2 implementation has proper rate-limiting controls
50%+ of connections terminated via TCP reset
Classification: LIKELY PROTECTED — verify with edge/infrastructure team
Meaning: Edge appliance or DDoS protection engaged at transport layer
Per-second reset rate drops significantly over time (late buckets <60% of early)
Classification: PARTIAL PROTECTION — confirm with infrastructure team
Meaning: Server or edge slowing the attack adaptively
Server sends REFUSED_STREAM (0x7) responses
Classification: PARTIAL PROTECTION — review rate limits
Meaning: Some stream-level rate-limiting in place
No ENHANCE_YOUR_CALM GOAWAY, no TCP resets, no throttling detected
Classification: VECTOR EXERCISABLE — exploitability unconfirmed
Important: This doesn't prove DoS exploitability. Edge volumetric/behavioral
protections (Akamai, CloudFlare) may engage at higher scales
============================================================
ENFORCEMENT SIGNAL ANALYSIS
============================================================
Server SETTINGS (initial frame):
HEADER_TABLE_SIZE = 4096
ENABLE_PUSH = True
MAX_CONCURRENT_STREAMS = 128
INITIAL_WINDOW_SIZE = 65535
MAX_FRAME_SIZE = 16384
→ MAX_CONCURRENT_STREAMS=128 is conservative (good post-CVE default)
GOAWAY breakdown across connections:
ENHANCE_YOUR_CALM (0xb): 3/5
Other GOAWAY codes: 1/5
No GOAWAY received: 1/5
TCP reset (RST at transport): 0/5
Total RST_STREAM frames from server: 2
REFUSED_STREAM frames from server: 0
Connections showing adaptive throttling: 1/5
============================================================
VERDICT
============================================================
✅ ENFORCEMENT CONFIRMED
3/5 connection(s) received GOAWAY with ENHANCE_YOUR_CALM (0xb).
This is the canonical signal that the CVE-2023-44487 mitigation is active.
Classification: NOT VULNERABLE — protocol-layer enforcement is engaged.
