Directive Analysis

default-srcHIGH

self *.chineseshipping.com.cn blob:

•Subdomain wildcard '*.chineseshipping.com.cn' in default-src - vulnerable to subdomain takeover

•HIGH RISK: 'blob:' URI in default-src allows script execution from dynamic blobs

style-srcHIGH

self *.chineseshipping.com.cn unsafe-inline unsafe-eval blob:

•Subdomain wildcard '*.chineseshipping.com.cn' in style-src - vulnerable to subdomain takeover

•Unsafe inline execution allowed in style-src

•Unsafe eval() execution allowed in style-src

•Info: 'blob:' URI in style-src

script-srcHIGH

Security Headers

✗Cross-Origin-Opener-PolicyMissing

Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.

How to add it:

nginx

add_header Cross-Origin-Opener-Policy "same-origin" always;

apache

Header always set Cross-Origin-Opener-Policy "same-origin"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set Cross-Origin-Opener-Policy to "same-origin"

✗Permissions-PolicyMissing

Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.

How to add it:

nginx

add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;

apache

Header always set Permissions-Policy "camera=(), microphone=(), geolocation=()"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set Permissions-Policy value

✗Referrer-PolicyMissing

Controls how much referrer information is sent with requests, preventing data leaks to third parties.

How to add it:

nginx

add_header Referrer-Policy "strict-origin-when-cross-origin" always;

apache

Header always set Referrer-Policy "strict-origin-when-cross-origin"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set Referrer-Policy to "strict-origin-when-cross-origin"

✗Strict-Transport-SecurityMissing

Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.

How to add it:

nginx

add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

apache

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"

cloudflare

SSL/TLS > Edge Certificates > Enable HSTS (toggle on, set max-age to 12 months, enable includeSubDomains)

✗X-Content-Type-OptionsMissing

Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.

How to add it:

nginx

add_header X-Content-Type-Options "nosniff" always;

apache

Header always set X-Content-Type-Options "nosniff"

cloudflare

Rules > Transform Rules > Managed Transforms > Enable "Add X-Content-Type-Options header"

✓X-Frame-OptionsPresent

SAMEORIGIN

Prevents the page from being embedded in iframes, protecting against clickjacking attacks.

—X-XSS-ProtectionDeprecated

Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.

Recommendations

→Add base-uri directive with appropriate restrictions
→Add connect-src directive with appropriate restrictions
→Add font-src directive with appropriate restrictions
→Add form-action directive with appropriate restrictions
→Add img-src directive with appropriate restrictions
→Add object-src directive with appropriate restrictions
→Consider implementing a stricter Content Security Policy
→Replace wildcards (*) with specific source lists
