- Ecosystems: maven
- Packages: org.eclipse.hawkbit:hawkbit-ddi-resource
## **Description**
A privilege escalation vulnerability has been identified in the Direct Device Integration (DDI) Controller of **Eclipse hawkBit** (versions 1.0.3 and prior).
This vulnerability allows an authenticated device to escalate its permissions and bypass the strict boundaries of its assigned updates. Under normal operation, a device should be restricted **strictly to the specific firmware artifacts explicitly assigned to it**. However, this flaw enables any authenticated device to bypass this restriction and download any firmware artifact **within the same tenant**.
This is **not** an authentication bypass; the requesting device must possess valid credentials for its respective tenant. Instead, the issue stems from a flaw in object-level authorization validation.
A related, lower-severity helper issue exists in the listing software modules artifacts metadata endpoint. This endpoint does not enforce assignment checks, enabling an authenticated device to list and enumerate available firmware artifacts, which can facilitate targeted exfiltration using the main download authorization bypass.

## **Impact**
* **Severity:** Moderate
* **Scope:** Tenant-isolated. An attacker must be an authenticated device within the target tenant to exploit this vulnerability.
* **Confidentiality Impact:** **Low**. While firmware binaries can be retrieved, the impact is mitigated because access is restricted strictly to the scope of the pre-authenticated tenant, and no administra…
