Critical Issues & Remediation Steps
1. Content Security Policy (CSP) - (Score: -20, Failed)
Issue:

The CSP policy includes unsafe directives (unsafe-inline, data: in script-src).
Overly broad source definitions (https: in object-src or script-src).
No restrictions on object-src or script-src.
Impact:

Makes the application vulnerable to Cross-Site Scripting (XSS) attacks.
Allows execution of inline scripts or data URIs that could be exploited.
Recommendation:

Remove unsafe-inline and data: from script-src.
Avoid overly broad sources like https:. Instead, use more specific hostnames.
Explicitly define object-src and script-src to restrict execution.
Example:

http
Kopieren
Bearbeiten
Content-Security-Policy: default-src 'self'; script-src 'self' https://trusted.example.com; object-src 'none'; frame-ancestors 'none';
2. Redirection - (Score: -5, Failed)
Issue:

HTTP to HTTPS redirection is done to a different host, preventing proper HSTS enforcement.
Impact:

Can expose users to Man-in-the-Middle (MITM) attacks before reaching the secure site.
HSTS headers won’t be recognized if set over HTTP.
Recommendation:

Redirect HTTP requests to the same host on HTTPS first.
Then perform any required redirection to the final host.
Example (Apache):

apache
Kopieren
Bearbeiten
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
Example (Nginx):

nginx
Kopieren
Bearbeiten
server {
    listen 80;
    server_name example.com;
    return 301 https://example.com$request_uri;
}
3. Referrer Policy - (Score: -5, Failed)
Issue:

Referrer-Policy header is set unsafely (origin, origin-when-cross-origin, unsafe-url, or no-referrer-when-downgrade).
Impact:

May expose sensitive URLs when navigating to external sites.
Recommendation:

Set Referrer-Policy to strict-origin-when-cross-origin (minimum requirement).
For stricter privacy, consider no-referrer.
Example:

http
Kopieren
Bearbeiten
Referrer-Policy: strict-origin-when-cross-origin
4. Subresource Integrity (SRI) - (Score: -5, Failed)
Issue:

SRI is not implemented for external scripts, though they are loaded over HTTPS.
Impact:

A compromised third-party script could introduce malicious code.
Recommendation:

Add the integrity attribute to external script imports.
Obtain the correct hash from a trusted source.
Example:

html
Kopieren
Bearbeiten
<script src="https://cdn.example.com/library.js" integrity="sha384-abc123..." crossorigin="anonymous"></script>
Passed, but Improvement Recommended
5. Strict Transport Security (HSTS) - (Score: 0, Passed)
Improvement:

Consider enabling preloading for stronger security.
This requires setting includeSubDomains and max-age=31536000 (1 year), then submitting to hstspreload.org.
Example:

http
Kopieren
Bearbeiten
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
6. Cross-Origin Resource Policy (CORP) - (Not Implemented)
Issue:

CORP is not explicitly set, meaning it defaults to cross-origin, allowing other sites to load resources.
Impact:

Could lead to unauthorized embedding or data leakage.
Recommendation:

Set Cross-Origin-Resource-Policy to restrict access.
Example:

http
Kopieren
Bearbeiten
Cross-Origin-Resource-Policy: same-origin
or

http
Kopieren
Bearbeiten
Cross-Origin-Resource-Policy: same-site
