| Название | lanyulei ferry <= 1.0.0 Authentication Bypass by Primary Weakness |
|---|
| Описание | ferry 1.0.0 and earlier validate session tokens with a JWT signing key that is either empty or left at the hard-coded factory default. An unauthenticated attacker who knows the token layout can mint a token carrying "rolekey": "admin" and an arbitrary future exp; the server accepts it as a fully privileged session.
The impact is amplified by the authorization design: the Casbin enforcer takes its subject directly from the rolekey claim inside the token and never re-reads the user's role from the database. Forging that one claim is therefore equivalent to holding the administrator role.
Because the same empty/default key also works across independent deployments of the product, this is a product-level defect rather than a single-site misconfiguration, and it can be mass-exploited via a search-engine fingerprint. |
