Summary
Vulnerability in Eclipse hawkBit versions 1.0.3 and prior in the Direct Device Integration (DDI) Controller. Allows an authenticated device to escalate privileges and download any firmware artifact within the same tenant, bypassing assignment restrictions. Additionally, the software module listing endpoint does not enforce assignment checks, enabling enumeration of available artifacts.
Risk Assessment
Risk includes unauthorized download and potential misuse of sensitive firmware updates, potentially leading to system integrity compromise and data leakage.
Recommendation
Upgrade Eclipse hawkBit to version 1.0.4 or later and implement proper access controls.

Original NVD description (English source)
In Eclipse hawkBit versions 1.0.3 and prior, a privilege escalation vulnerability (CWE-284 / CWE-862) has been identified in the Direct Device Integration (DDI) Controller. 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.
