SonicWall Security Audit Toolkit

Automated security assessment framework for SonicWall appliances. For authorized penetration testing engagements only.

Quick Start

# Install dependencies
pip install -r requirements.txt

# Run all modules against a target
python3 sonicwall_audit.py --target 192.168.1.1 --port 8443

# Run specific modules
python3 sonicwall_audit.py -t 192.168.1.1 -p 8443 -m ssl,cve

# Verbose output
python3 sonicwall_audit.py -t 192.168.1.1 -p 8443 -v

# JSON-only output
python3 sonicwall_audit.py -t 192.168.1.1 -p 8443 --format json

Modules

Module	Description	Risk Level
`ssl`	SSL/TLS config: certs, protocols, ciphers, HSTS	Passive
`cve`	Known CVE detection via fingerprinting	Passive
`auth`	Default creds, session security, rate limiting	Active (low)
`web`	Headers, info disclosure, API exposure, methods	Passive/Active

What Each Module Checks

SSL (`ssl`)

Certificate validity, expiry, key strength, signature algorithm
Protocol versions: SSLv3, TLS 1.0/1.1/1.2/1.3
Cipher suite strength
HSTS header

CVE Scanner (`cve`)

Appliance fingerprinting (product type, firmware version)
Non-destructive checks for: CVE-2021-20016, CVE-2021-20038, CVE-2023-0656, CVE-2023-44221, CVE-2024-40766, CVE-2024-53704, CVE-2024-53705, CVE-2025-23006
Does NOT attempt exploitation

Authentication (`auth`)

Factory default credential testing (admin/password, admin/admin)
Login form CSRF protection
Session cookie flags (Secure, HttpOnly, SameSite)
Rate limiting detection
Security headers on login page

Web Interface (`web`)

HTTP method testing (TRACE, PUT, DELETE)
Security headers audit (HSTS, CSP, X-Frame-Options, etc.)
Version/technology disclosure
Error page information leakage
Directory listing
Exposed API endpoints
HTTP-to-HTTPS redirect

Output

Reports are saved to reports/ (configurable with --output-dir):

sonicwall_audit_YYYYMMDD_HHMMSS.json — Machine-readable
sonicwall_audit_YYYYMMDD_HHMMSS.txt — Human-readable with severity ratings

Exit Codes

Code	Meaning
0	No critical or high findings
1	High severity findings
2	Critical severity findings

Vulnerable Lab (CTF)

A Docker-based practice lab with real exploitable vulnerabilities simulating two critical SonicWall CVEs. Both containers replicate real SonicWall response patterns so the audit toolkit can be tested against them.

cd lab && docker-compose up --build -d

Container	Port	CVE	Challenge
`sonicwall-sma100`	8443	CVE-2021-20038	Stack buffer overflow in CGI binary → RCE
`sonicwall-sslvpn`

Exploit skeletons are in lab/exploits/, working solutions in lab/solutions/. Full walkthrough: lab/WALKTHROUGH.md

CI/CD Integration

# Returns non-zero exit code on critical/high findings
python3 sonicwall_audit.py -t $TARGET -p 8443 --format json -m ssl,cve,web
echo $?  # 0=pass, 1=high, 2=critical

Adding Custom CVE Checks

Edit modules/cve_scanner.py and add entries to SONICWALL_CVES:

{
    "cve": "CVE-YYYY-NNNNN",
    "cvss": 9.8,
    "severity": "CRITICAL",
    "title": "Description",
    "description": "Full description",
    "check": "_check_cve_yyyy_nnnnn",  # method name
    "remediation": "Update to version X.",
    "affected_products": ["SonicOS"],
}

Then implement the corresponding _check_cve_yyyy_nnnnn(self, cve_info) method.
