A 403 appears, or mcp-servers/tool_resolver.py's classify_block()
returns "waf" on a tool's output. Work the tiers in order before giving
up on a blocked endpoint you actually need to test.
Tiers 1-4 below are automated by mcp-servers/waf-bypass-mcp's
attempt_bypass(url, baseline_status, tiers) -- call that first rather
than hand-crafting each variant; it runs all of them in one call and
reports which (if any) changed the response. This skill documents what
it's actually doing, plus Tier 5, which isn't automated (it needs
external OSINT, not a retry loop).
X-Forwarded-For / X-Real-IP / X-Originating-IP /
X-Remote-IP / X-Client-IP / X-Custom-IP-Authorization /
X-ProxyUser-Ip / True-Client-IP / Forwarded: for=127.0.0.1;host=localhost
-- set to 127.0.0.1/localhost on the blocked endpoint.Host: localhost, 127.0.0.1, internal.<domain>.URL-encode letters (%61dmin), %2f for /, trailing space/tab/null,
--path-as-is with ./, /., //, /../, %2e; case variations
(Admin, ADMIN); extension append (.json/.html/.php/;.js/#).
POST/PUT/PATCH/OPTIONS/TRACE/HEAD/CONNECT plus method
override headers (X-HTTP-Method-Override, X-Method-Override,
_method=).
--http1.0/--http1.1, --http2, --http2-prior-knowledge.
Find the origin IP (SecurityTrails/Shodan/Censys/CT logs), then
--resolve <domain>:443:<IP> or -H "Host: <domain>" straight to the
IP; spoof CF-Connecting-IP/CF-IPCountry; reuse cf_clearance if
known. This needs real OSINT lookups per target, not a retry loop, which
is why waf-bypass-mcp doesn't automate it.
Still 403 after all tiers -> document the host as WAF-protected and move on. If the target is heavily WAF-protected, research current WAF-bypass techniques for that specific vendor online, apply them; if bypass still fails, move on rather than looping.
| curl error | Meaning | Fix |
|---|---|---|
| (6) DNS | Couldn't resolve host | --dns-servers 8.8.8.8 |
| (7) port closed | Connection refused | try 80/8080/8443 |
| (35) SSL | SSL handshake failed | -k / --tlsv1.2 |
| (52) empty reply | Server closed connection | --http1.1 |
| (56) recv failure | Receive error | retry with delay + a legit UA |
