Executive Summary
This report documents the findings from a static security analysis of the Kumori Cloud web application. The assessment focused on identifying common web vulnerabilities including XSS, CSRF, injection flaws, and insecure configurations.
Findings
The application does not implement a Content-Security-Policy header. While this is a static site with no server-side processing, in a production environment this could allow XSS attacks if user-generated content were introduced.
Content-Security-Policy: default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';
Remediation: Add CSP headers via web server configuration (Nginx/Apache). For static sites, this is implemented at the web server level rather than in application code.
The application headers do not include X-Frame-Options, which could allow clickjacking attacks in a production environment where authenticated sessions exist.
X-Frame-Options: SAMEORIGIN
Remediation: Add X-Frame-Options header in web server configuration. Already documented in DEPLOY.md for Nginx/Apache/Caddy setups.
The blog page uses inline onclick handlers. While not a vulnerability in itself for a static site, this pattern is discouraged by CSP best practices.
Remediation: Event handlers have been moved to external JavaScript in the blog page update. All interactivity is now attached via addEventListener.
The portal login page accepts any credentials but returns a generic authentication failure. This is intentional as the portal is under active development and backend integration is pending.
Remediation: Portal pages reference internal directory services. Backend authentication integration is scheduled for Q2 2025. No credentials are stored locally.
The portal dashboard shows "internal orchestration service" errors. While these are internal service names, they could be misinterpreted as real infrastructure details.
Remediation: Error messages have been reviewed to ensure they reference internal services only. No real infrastructure details are exposed.
This is a fully static website with no server-side code, database connections, or API endpoints. As such, many traditional web vulnerabilities (SQL injection, command injection, insecure deserialization) are not applicable.
Note: If server-side functionality is added in the future, a full security review should be conducted including input validation, parameterized queries, and proper authentication.
Recommendations
- Implement all security headers at the web server level (CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy)
- Enable HTTPS with HSTS for all domains
- If adding server-side functionality, implement proper input validation and output encoding
- Regular dependency scanning if Node.js/npm packages are introduced
- Conduct periodic penetration testing for production deployments
