Summary

The NodeJS version of HAX CMS has a disabled Content Security Policy (CSP). This configuration is insecure for a production application because it does not protect against cross-site-scripting attacks.

Details

The contentSecurityPolicy value is explicitly disabled in the application's Helmet configuration in app.js.

Affected Resources

• app.js:52

PoC

To reproduce this vulnerability, install HAX CMS NodeJS. The application will load without a CSP configured.

Impact

In conjunction with an XSS vulnerability, an attacker could execute arbitrary scripts and exfiltrate data, including session tokens and sensitive local data.
