Certified Ethical Hacker (CEH) Practice Question

During a gray-box assessment you notice the target web application propagates its session identifier as a long Base64 token appended to the query string of every internal hyperlink (for example, /dashboard?sid=eyJhbGciOi…). From a web application security perspective, what is the primary risk introduced by carrying authentication data in the URL instead of in an HttpOnly cookie?

  • JavaScript running in the same origin cannot read the token, preventing the application from implementing effective CSRF defenses.

  • The session token may leak through browser history, server logs, and Referer headers, making it easy for attackers to steal and reuse it.

  • Browsers will refuse to transmit the token over HTTPS connections, so authenticated requests will fail when TLS is used.

  • Placing the token in the URL disables the browser's same-origin policy, allowing any external domain to issue privileged requests.
