# pentest-web

Web app saldiri yuzeyi advisory + Burp/ZAP cikti analizi + OWASP Top 10 methodology. Live exploit composer'lama scope deklare ile yapilir; otomatik exploit calistirma yok.

## Triggers

- "OWASP Top 10 test"
- "Burp ciktisi inceleyin"
- "SQL injection bulduk mu"
- "XSS testi yapalim"
- "SSRF / IDOR / auth bypass arar misin"
- "request smuggling"

## OWASP Top 10 Kontrol Listesi

| # | Kategori | Test Yaklasimi |
|---|----------|---------------|
| A01 | Broken Access Control | Yatay/dikey IDOR, force browse, JWT manipulation |
| A02 | Cryptographic Failures | TLS config, parola hash, sensitive data unencrypted |
| A03 | Injection | SQLi (in-band, blind, OOB), NoSQL, OS command, XPath |
| A04 | Insecure Design | Rate limit eksik, business logic flaw |
| A05 | Security Misconfig | Default cred, verbose error, exposed admin panel |
| A06 | Vulnerable Components | Dependency CVE, framework version |
| A07 | Auth Failures | Brute force, password reset, session fix |
| A08 | Software/Data Integrity | Unsigned update, deserialization |
| A09 | Logging Failures | Bypass detection, audit gap |
| A10 | SSRF | Internal port reach, cloud metadata steal |

## Burp/ZAP Cikti Analizi

Kullanici Burp Pro/CE veya ZAP report yapistirirsa:

```markdown
## Burp Active Scan — analiz

### True Positive
- High: SQL Injection in /api/users?id= (Time-based, MySQL)
  - Payload: `1' AND SLEEP(5)-- -`
  - Etki: Tam DB okuma + potential RCE (FILE priv varsa)
- Medium: Reflected XSS in /search?q= (no CSP)

### False Positive (elenir)
- Info: Server header reveals nginx — bilgi sizintisi degil, fix oncelik dusuk
- Low: Cookie missing HttpOnly — only-server cookie, JS erisimi yok

### Onerilen Manuel Test
- IDOR check /api/users/{id} — auth bypass denemesi
- Race condition /api/purchase (5 paralel istek)
- JWT alg=none + alg=HS256 ile RSA key swap
```

## Yaygin Methodology Akisi

```
1. Recon: subfinder + httpx + wappalyzer
2. Crawl: ffuf / gobuster / katana (rate-limited)
3. Param discovery: paramspider / Arjun
4. Active probe: nuclei templates + manual Burp
5. Auth test: JWT decode + signature check + algorithm swap
6. Bizlogic: race, IDOR, price manipulation (pentest-bizlogic'e devret)
7. Report: OWASP severity + CVSS + remediation
```

## Onerilen Komutlar (Scope ile)

```bash
# MODERATE — content discovery (rate limit)
ffuf -w wordlist.txt -u https://<hedef>/FUZZ -t 20 -p 0.1 -mc 200,301,403 -o ffuf_<hedef>_$(date +%Y%m%d_%H%M%S).json

# MODERATE — auto template scan
nuclei -u https://<hedef> -severity medium,high,critical -rate-limit 50 -o nuclei_<hedef>_$(date +%Y%m%d_%H%M%S).txt

# LOUD — SQLi targeted (sadece tek param + level 1)
# sqlmap kullanim onerilir ama composer'lama icin scope deklare zorunlu
```

## JWT Test Onerisi

```bash
# Manuel decode (QUIET, hicbir hedefe istek atmaz)
echo <token> | cut -d. -f2 | base64 -d | jq .

# Common bypass denemeleri
# alg: "none"          -> imza atla
# alg: HS256 + RSA pub -> public key ile HMAC
# kid: ../../etc/passwd -> path traversal
# exp manipulation
```

## CSP / Header Analiz

```bash
# QUIET — header sadece
curl -sI https://<hedef> | grep -iE 'content-security-policy|x-frame-options|strict-transport|x-content-type'
```

## Out-of-Scope

- Live sqlmap orchestration (kullanici yetkili `sqlmap` calistirir)
- Mass scan, parallel attacks on multiple targets
- Automated exploitation (PoC validation pentest-exploit-chain'de)
- DoS denemesi
