Vulnerability Scanner

Advanced vulnerability analysis for OWASP 2025, supply chain security, attack surface mapping, and risk prioritization.

Description

USE WHEN:

Auditing code for security vulnerabilities
Reviewing dependencies for supply chain risks
Scanning for hardcoded secrets or credentials
Identifying dangerous code patterns (injection, XSS, deserialization)
Preparing for security audits or penetration tests
Prioritizing vulnerability remediation by risk

DON'T USE WHEN:

Need runtime dynamic analysis (use actual pentest tools)
Scanning compiled binaries (this is source-code focused)
Need compliance-specific audits (PCI-DSS, HIPAA have dedicated tools)

Scripts

Script	Purpose	Usage
scripts/security_scan.py	Full security scan	`python scripts/security_scan.py [--scan-type all\`	deps\	secrets\	patterns\	config]

Quick Start

bash

# Full scan
python scripts/security_scan.py /path/to/project

# Just check for secrets
python scripts/security_scan.py /path/to/project --scan-type secrets

# Summary output
python scripts/security_scan.py /path/to/project --output summary

Reference Files

File	Purpose
checklists.md	OWASP Top 10, Auth, API, Data protection checklists

1. Security Expert Mindset

Core Principles

Principle	Application
Assume Breach	Design as if attacker already inside
Zero Trust	Never trust, always verify
Defense in Depth	Multiple layers, no single point
Least Privilege	Minimum required access only
Fail Secure	On error, deny access

Threat Modeling Questions

Before scanning, ask:

What are we protecting? (Assets)
Who would attack? (Threat actors)
How would they attack? (Attack vectors)
What's the impact? (Business risk)

2. OWASP Top 10:2025

Risk Categories

Rank	Category	Think About
A01	Broken Access Control	Who can access what? IDOR, SSRF
A02	Security Misconfiguration	Defaults, headers, exposed services
A03	Software Supply Chain 🆕	Dependencies, CI/CD, build integrity
A04	Cryptographic Failures	Weak crypto, exposed secrets
A05	Injection	User input → system commands
A06	Insecure Design	Flawed architecture
A07	Authentication Failures	Session, credential management
A08	Integrity Failures	Unsigned updates, tampered data
A09	Logging & Alerting	Blind spots, no monitoring
A10	Exceptional Conditions 🆕	Error handling, fail-open states

2025 Key Changes

text

2021 → 2025 Shifts:
├── SSRF merged into A01 (Access Control)
├── A02 elevated (Cloud/Container configs)
├── A03 NEW: Supply Chain (major focus)
├── A10 NEW: Exceptional Conditions
└── Focus shift: Root causes > Symptoms

3. Supply Chain Security (A03)

Attack Surface

Vector	Risk	Question to Ask
Dependencies	Malicious packages	Do we audit new deps?
Lock files	Integrity attacks	Are they committed?
Build pipeline	CI/CD compromise	Who can modify?
Registry	Typosquatting	Verified sources?

Defense Principles

Verify package integrity (checksums)
Pin versions, audit updates
Use private registries for critical deps
Sign and verify artifacts

4. Attack Surface Mapping

What to Map

Category	Elements
Entry Points	APIs, forms, file uploads
Data Flows	Input → Process → Output
Trust Boundaries	Where auth/authz checked
Assets	Secrets, PII, business data

Prioritization Matrix

text

Risk = Likelihood × Impact

High Impact + High Likelihood → CRITICAL
High Impact + Low Likelihood  → HIGH
Low Impact + High Likelihood  → MEDIUM
Low Impact + Low Likelihood   → LOW

5. Risk Prioritization

CVSS + Context

Factor	Weight	Question
CVSS Score	Base severity	How severe is the vuln?
EPSS Score	Exploit likelihood	Is it being exploited?
Asset Value	Business context	What's at risk?
Exposure	Attack surface	Internet-facing?

Prioritization Decision Tree

text

Is it actively exploited (EPSS >0.5)?
├── YES → CRITICAL: Immediate action
└── NO → Check CVSS
         ├── CVSS ≥9.0 → HIGH
         ├── CVSS 7.0-8.9 → Consider asset value
         └── CVSS <7.0 → Schedule for later

6. Exceptional Conditions (A10 - New)

Fail-Open vs Fail-Closed

Scenario	Fail-Open (BAD)	Fail-Closed (GOOD)
Auth error	Allow access	Deny access
Parsing fails	Accept input	Reject input
Timeout	Retry forever	Limit + abort

What to Check

Exception handlers that catch-all and ignore
Missing error handling on security operations
Race conditions in auth/authz
Resource exhaustion scenarios

7. Scanning Methodology

Phase-Based Approach

8. Code Pattern Analysis

High-Risk Patterns

Pattern	Risk	Look For
String concat in queries	Injection	"SELECT * FROM " + user_input
Dynamic code execution	RCE	eval(), exec(), Function()
Unsafe deserialization	RCE	pickle.loads(), unserialize()
Path manipulation	Traversal	User input in file paths
Disabled security	Various	verify=False, --insecure

Secret Patterns

Type	Indicators
API Keys	api_key, apikey, high entropy
Tokens	token, bearer, jwt
Credentials	password, secret, key
Cloud	AWS_, AZURE_, GCP_ prefixes

9. Cloud Security Considerations

Shared Responsibility

Layer	You Own	Provider Owns
Data	✅	❌
Application	✅	❌
OS/Runtime	Depends	Depends
Infrastructure	❌	✅

Cloud-Specific Checks

IAM: Least privilege applied?
Storage: Public buckets?
Network: Security groups tightened?
Secrets: Using secrets manager?

10. Anti-Patterns

❌ Don't	✅ Do
Scan without understanding	Map attack surface first
Alert on every CVE	Prioritize by exploitability + asset
Ignore false positives	Maintain verified baseline
Fix symptoms only	Address root causes
Scan once before deploy	Continuous scanning
Trust third-party deps blindly	Verify integrity, audit code

11. Reporting Principles

Finding Structure

Each finding should answer:

What? - Clear vulnerability description
Where? - Exact location (file, line, endpoint)
Why? - Root cause explanation
Impact? - Business consequence
How to fix? - Specific remediation

Severity Classification

Severity	Criteria
Critical	RCE, auth bypass, mass data exposure
High	Data exposure, privilege escalation
Medium	Limited scope, requires conditions
Low	Informational, best practice

Remember: Vulnerability scanning finds issues. Expert thinking prioritizes what matters. Always ask: "What would an attacker do with this?"
