Technical details
The vulnerability is an improper access control flaw in the Tenant Administrator Management API exposed at the /admin/ endpoint of diboot 3.8.0. The root cause is insufficient validation of the tenantId parameter passed to the TenantController, allowing attackers to manipulate it to access resources across tenant boundaries. The attack is network-reachable and may require low-level authentication depending on the endpoint's exposure. A successful exploit grants an attacker the ability to read and potentially modify administrative configuration for other tenants. No patch is currently available; the vendor did not respond to early disclosure.
