Impact on Systems
✅ Session Hijacking: Attackers can steal active user session tokens (cookies) to impersonate the victim.
✅ Phishing Execution: Malicious scripts can dynamically alter DOM content to present fraudulent login forms.
✅ Worm Propagation: Stored XSS can spread autonomously as users visit the infected page.
How to fix this issue?
Implement the following strategic mitigations immediately to eliminate the attack surface.
1. Output Encoding Implement strict context-aware output encoding (HTML, JavaScript, Attribute, CSS) before rendering user data.
2. Content Security Policy (CSP) Deploy a rigorous CSP header to restrict script execution exclusively to trusted domains.
3. Framework Defenses Utilize native UI framework protections (e.g., React DOM escaping) and avoid dangerouslySetInnerHTML.
Vulnerability Signature
// Example DOM-based XSS vulnerability
const user_input = new URLSearchParams(window.location.search).get('q');
// VULNERABLE: Direct insertion into innerHTML
document.getElementById('results').innerHTML = "Results for: " + user_input;
// EXPLOIT PAYLOAD: ?q=\<img src=x onerror=alert(document.cookie)\>
