Base vector

AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N

Name of the Vulnerable Software and Affected Versions Crabbox versions prior to 0.12.0

Description Insufficient access control checks allow users with shared visibility-only access to escalate privileges. By sending POST requests to the endpoints "/v1/leases/:id/code/ticket", "/v1/leases/:id/webvnc/ticket", and "/v1/leases/:id/egress/ticket", attackers can obtain Code, WebVNC, and Egress agent tickets. This enables the impersonation of trusted lease-side bridges despite the user having only visibility permissions.

Recommendations Update to version 0.12.0 or later.
