Common Penetration Testing Vulnerabilities
Critical security issues we identify in penetration testing Web3 applications
Frontend Security Issues
Cross-Site Scripting (XSS)
Unvalidated user input rendering in React components, potentially modifying transaction data.
Client-Side Bypasses
Access control checks that can be bypassed through browser developer tools.
Hardcoded Secrets
API keys, private keys, or sensitive endpoints exposed in frontend bundles.
Backend & API Issues
Injection Attacks
SQL injection, NoSQL injection, and command injection through unvalidated inputs.
Authentication Flaws
Weak JWT implementations, session management issues, and privilege escalation.
CORS Misconfigurations
Overly permissive CORS policies allowing unauthorized cross-origin requests.
Penetration Testing Methodology
Systematic approach following industry standards and Web3-specific techniques
Reconnaissance
Information gathering, asset discovery, and attack surface mapping.
Scanning
Vulnerability scanning, port enumeration, and service identification.
Exploitation
Active exploitation of identified vulnerabilities and attack paths.
Post-Exploitation
Privilege escalation, lateral movement, and impact assessment.
Reporting
Detailed findings with remediation steps and risk prioritization.
Real-World Impact
How our penetration testing prevents real security incidents
Critical XSS Prevention
Initia Protocol Frontend Audit
In our recent collaboration with Pashov Audit Group for Initia Protocol, we identified a high-severity XSS vulnerability in the penetration testing frontend. Unvalidated user input was being rendered directly in React components, which could have allowed attackers to:
- • Execute malicious scripts in users' browsers
- • Modify transaction data before signing
- • Steal sensitive user information and wallet data
- • Redirect users to phishing sites
By identifying and fixing this vulnerability before launch, we helped secure user flows and protect sensitive data for thousands of potential users.
Test Your Security Before Attackers Do
Comprehensive penetration testing to identify and fix vulnerabilities across your entire Web3 infrastructure.
