High Severity Vulnerabilities

• CVE-2019-9169: glibc string function vulnerabilities
• CVE-2017-9047: sprintf() format string vulnerabilities
• CVE-2018-16529: strcat() buffer overflow

Advanced Patterns

• CVE-2016-3706: alloca() stack exhaustion
• CVE-2017-1000366: Stack clash vulnerabilities
• CVE-2000-0573: Format string vulnerabilities

[!] Ditemukan 8 potensi kerentanan:

🔴====================  CRITICAL SEVERITY (2 items)  ====================

     File: `test_vulnerable.c` | Line: 12
     Function/Pattern: `gets`
     Description: Fungsi gets() tidak melakukan bound checking, sangat mudah di-overflow
     CVE References: CVE-2012-3489, CVE-2015-1781, CVE-2016-4051
     Remediation: Gunakan fgets() dengan buffer size yang tepat
     Code: `gets(buffer);  // Dangerous! No bounds checking`
     Example Exploit: payload = "A" * 1024 + return_address

HASIL ANALISIS CRASH
============================================================
Crash Type: segmentation_fault
Exploitability: high

Register States:
  EIP: 0x41414141
  ESP: 0xbffff6a0

[!!!] CRASH TERDETEKSI! (Segmentation Fault)
[+] Instruction Pointer (EIP) tertimpa dengan nilai: 0x41414141
[+] 🎯 Offset kerentanan berhasil ditemukan: 268
[+] Arsitektur: 32-bit (little-endian)

[+] REKOMENDASI EKSPLOITASI:
  1. Buat skrip PoC: python BOAR_beta.py poc ./vulnerable_binary --offset 268
  2. Gunakan offset 268 untuk mengontrol EIP
  3. ⚠️  Stack canary aktif - perlu bypass atau leak canary

🎓 Educational Examples

Test Program

Use the included test_vulnerable.c to test BOAR's capabilities:

# Compile the test program
gcc -o test_vulnerable test_vulnerable.c -fno-stack-protector

# Test static analysis
python BOAR_beta.py static test_vulnerable.c

# Test dynamic analysis
python BOAR_beta.py dynamic ./test_vulnerable -l 500

# Test specific vulnerability
echo "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" | ./test_vulnerable 1

🛡️ Security Protections Detected

BOAR can detect and provide bypass advice for:

• Stack Canaries: Detects stack protection and suggests bypass techniques
• NX/DEP: Identifies non-executable stack and recommends ROP
• PIE: Detects position-independent executables and suggests info leaks

• ASLR: Detects address space layout randomization

📋 Remediation Recommendations

For each vulnerability found, BOAR provides:

• Specific CVE references for context
• Detailed remediation steps with code examples
• Secure coding alternatives for dangerous functions
• Protection bypass techniques for educational purposes
• Real-world exploit examples for understanding impact

🔗 Integration

BOAR can be integrated with:

• CI/CD pipelines for automated security testing
• IDE plugins for real-time vulnerability detection
• Security scanners as a specialized buffer overflow module
• Penetration testing frameworks for exploit development
