A successful forced browsing attack indicates a vulnerability in
-
The configuration management
-
The session management
-
The change management process
-
The authorization process
Forced browsing (or path traversal) attacks succeed when the application fails to check if a user is authorized to access a specific URL or resource. The attacker guesses or enumerates URLs and accesses them directly without proper permission checks. This is fundamentally an authorization failure - the application authenticated the user but didn't verify their right to access that specific resource.
Forced/forceful browsing succeeds when a user reaches a resource or page they shouldn't be permitted to access simply by guessing or directly requesting its URL — that's fundamentally a failure to check whether the requester is authorized for that resource. It's not about configuration, session handling, or change control, since the session and identity may be entirely valid; it's the missing per-resource authorization check that lets the attack through.
