Which application attack is being tested if the URL shows a session ID after clicking a link?

The scenario described points to session replay attacks, where an attacker might capture valid session IDs and replay them to access a user’s session after the ID has been transmitted over a network. When a URL shows a session ID, it indicates that the application is relying on this identifier to maintain or validate session states. If an attacker can capture this session ID (through methods such as eavesdropping or man-in-the-middle attacks), they can potentially impersonate the legitimate user by reusing the session ID.

In the context of application security, revealing session IDs in URLs can expose vulnerabilities because these identifiers can be intercepted or logged in various places (like browser history or server logs). Once the attacker obtains the session ID, they can gain unauthorized access to the user’s session. This is why it specifically represents a session replay attack.

The other attack types do not relate directly to the exposure of session IDs in the URL. For example, pass-the-hash involves the use of hashed credentials without needing the plaintext password; object deference relates to access control mechanisms being bypassed; and cross-site request forgery (CSRF) involves tricking a user into unknowingly submitting requests to vulnerable applications where they are already authenticated. Hence, each of these paths addresses different
