Havainnot
Jokainen havainto: ongelma, missä, vaikutus, omistaja, PoC, korjaus, validointi.
XML-RPC fully enabled
KORKEAhttps://tieturi.fi/ — POST system.listMethods returns large method set (system.multicall, wp., metaWeblog., pingback., WPML translationproxy., …). last_reprobe=2026-07-31.
XML-RPC enables amplified brute force and pingback abuse.
- Human: Public xmlrpc surface on tieturi.fi expands attacker recon.
- Agent (LLM+tools): Keep surface in continuous recon.
- If invasive/destructive: Escalate if second bug/credential. L3 public-max is read-only.
Tieturi — turva / tuote / infra (vahvista omistaja)
Read-only. Does not change the system.
curl -sS -X POST https://tieturi.fi/xmlrpc.php -H 'Content-Type: text/xml' --data '<?xml version="1.0"?><methodCall><methodName>system.listMethods</methodName></methodCall>' | head -c 500
Disable XML-RPC if unused; WAF rate-limit; block system.multicall from internet.
Continuous automated abuse.
SSH TCP/22 open on web IP
KORKEAWhat / evidence: Live connect to port 22 open on https://tieturi.fi / www. Fix: Bastion/VPN only; key-only last_reprobe=2026-07-31.
SSH on public web IP is a permanent brute-force target.
tieturi.fi · TCP/22
- Human: SSH on public IP is a permanent brute-force target.
- Agent (LLM+tools): Port-scan brand IPs; spray against TCP/22.
- If invasive/destructive: Shell on host. L3 only proves port open.
Tieturi — turva / tuote / infra (vahvista omistaja)
Read-only. Does not change the system.
nc -zv -w 3 tieturi.fi 22
Close TCP/22 on public edge or restrict by allowlist/bastion; keys-only; fail2ban; no password auth.
Exposure remains until closed.
Dangerous HTTP methods (deep matrix)
KORKEAhttps://tieturi.fi/ — What / evidence: Deep: TRACE/PUT/DELETE/PATCH returned 200 HTML — re-baseline methods on edge. Fix: Force 405 for TRACE/write verbs last_reprobe=2026-07-31.
Public brand surface on tieturi.fi expands recon until closed.
- Human: Public edge surface on tieturi.fi expands attacker recon.
- Agent (LLM+tools): Keep surface in continuous recon.
- If invasive/destructive: Escalate if second bug/credential. L3 public-max is read-only.

Read-only. Does not change the system.
curl -sSI 'https://tieturi.fi/'
Remove unnecessary public hosts on tieturi.fi DNS or enforce strong auth/WAF; re-test from internet.
Exposure remains until closed.
Public wp-login + weak headers
KORKEAhttps://tieturi.fi/wp-login.php — What / evidence: wp-login public; CSP/XFO/nosniff missing (only HSTS class). Fix: MFA/WAF + full headers last_reprobe=2026-07-31.
Default WP login is a permanent spray target.
- Human: Public wp_login surface on tieturi.fi expands attacker recon.
- Agent (LLM+tools): Keep surface in continuous recon.
- If invasive/destructive: Escalate if second bug/credential. L3 public-max is read-only.
Tieturi — turva / tuote / infra (vahvista omistaja)
Read-only. Does not change the system.
curl -sSI 'https://tieturi.fi/wp-login.php'
MFA, rate limit, WAF, optional allowlist; combine with blocking user REST enum.
Exposure remains until closed.
DMARC quarantine pct=25
KESKIDNS TXT at _dmarc.tieturi.fi publishes a DMARC policy with p=none (monitor-only). Receiving servers do not quarantine/reject forged @tieturi.fi mail on DMARC fail. This is email brand spoofing / BEC risk, not a website bug. Proof: dig TXT _dmarc.tieturi.fi +short last_reprobe=2026-07-31.
Brand email spoofing / BEC remains easier while DMARC on tieturi.fi is not reject.
DNS record (not a website): _dmarc.tieturi.fi TXT
Mail domain: @tieturi.fi
- Human: Forge invoices / IT resets as
@tieturi.fiwhilep=none. - Agent (LLM+tools): Re-check DMARC; automate brand-domain spoof campaigns.
- If invasive/destructive: Financial fraud via trusted-looking mail — not CMS takeover from this alone. L3 only proves DNS policy (dig).
Tieturi — turva / tuote / infra (vahvista omistaja)
Read-only. Does not change the system.
dig TXT _dmarc.tieturi.fi +short
Align SPF/DKIM for all legitimate senders; move DMARC to p=quarantine then p=reject; monitor rua; document third-party senders.

Fat SPF ~all
KESKImulti-vendor softfail (surface: https://tieturi.fi/). last_reprobe=2026-07-31.
Weak SPF increases spoof windows for the brand domain.
- Human: Public spf surface on tieturi.fi expands attacker recon.
- Agent (LLM+tools): Keep surface in continuous recon.
- If invasive/destructive: Escalate if second bug/credential. L3 public-max is read-only.

Liitteet (AWP + Core)
Oikea pack L3 max retestistä 2026-07-31 (public-max, ei-tuhoava). Jokaisella tiedostolla on kuvateksti.
Mikä se on: allekirjoitettu Agent Witness Protocol -kuitti (offline-tarkistettava).
Mitä se todistaa: meidän testi-/engagement-lokimme eheyden.
Mitä se EI ole: ei yksin todista bugia hostissanne (se on kunkin havainnon PoC).
→ lataa awp-receipt.json
Miten AWP:ta käytetään / varmennetaan (open-source)
npx agent-witness-protocol verify awp-receipt.json
PASS (rehellisesti): kuitin allekirjoitus ja Merkle-todiste ok — testiloki on ehjä.
PASS ei tarkoita: että tuotantobugi on korjattu, tai että PayBotFin live-witness oli käytössä (local_awp_dev / DEV_LAB).
Korjausjärjestys tiimille
- Sulje HIGH-julkiset altistukset ensin (auth / VPN / DNS).
- Korjaa MEDIUM-otsikot, postikäytäntö ja non-prod.
- Uudelleentestaa PoC:t julkisesta netistä kunnes kiinni.
- Arkistoi AWP/evidence auditointia ja retestiä varten.
