Description

In Eclipse BaSyx Go Components versions up to and including 1.0.0, ABAC-enabled deployments are vulnerable to an authorization bypass caused by inconsistent trailing-slash handling between the ABAC middleware and the HTTP router.

The shared router configuration used Chi's middleware.StripSlashes, so a request such as GET /shells/ was dispatched to the registered GET /shells route. However, the ABAC middleware evaluated the original request path including the trailing slash. If ABAC route lookup did not find a matching slash-suffixed route, the request was passed onward and the router then stripped the slash and executed the protected handler without the intended ABAC authorization decision and without the expected ABAC query filters.

An unauthenticated or unauthorized network attacker could append a trailing slash to protected API routes to reach handlers that should have been denied by ABAC policy. Depending on the exposed component, HTTP method, and deployed policy, this could allow unauthorized read, create, update, delete, or upload operations.

The issue affects ABAC-enabled deployments of services that use the shared router and ABAC middleware, including AAS Repository, Submodel Repository, AAS Registry, Submodel Registry, Concept Description Repository, Discovery, AAS Environment upload, and related services. The issue is fixed in Eclipse BaSyx Go Components v1.0.1.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
