Hậu quả phổ biến
| Phạm vi | Tác động | Khả năng xảy ra |
|---|---|---|
| Confidentiality Integrity Access Control Authentication Authorization Availability Accountability | Gain Privileges or Assume Identity, Bypass Protection Mechanism, Execute Unauthorized Code or Commands, Modify Memory, Modify Files or Directories Ghi chú: Depending on the access to debug component(s) erroneously granted, an attacker could use the debug component to gain additional understanding about the system to further an attack and/or execute other commands. This could compromise any security property, including the ones listed above. | Medium |
Ví dụ đã quan sát
| Tài liệu tham khảo | Mô tả |
|---|---|
CVE-2017-18347 | Incorrect access control in RDP Level 1 on STMicroelectronics STM32F0 series devices allows physically present attackers to extract the device's protected firmware via a special sequence of Serial Wire Debug (SWD) commands because there is a race condition between full initialization of the SWD interface and the setup of flash protection. |
CVE-2020-1791 | There is an improper authorization vulnerability in several smartphones. The system has a logic-judging error, and, under certain scenarios, a successful exploit could allow the attacker to switch to third desktop after a series of operations in ADB mode. (Vulnerability ID: HWPSIRT-2019-10114). |
Các biện pháp giảm thiểu tiềm năng
Phases : ImplementationEnsure that debug components are properly chained and their granularity is maintained at different authentication levels.
Phương pháp phát hiện
Architecture or Design Review
Appropriate Post-Si tests should be carried out at various authorization levels to ensure that debug components are properly chained and accessible only to users with appropriate credentials.Hiệu quả : High

Ghi chú ánh xạ lỗ hổng
Lý do : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.Bình luận : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
