Consecuencias comunes
| Alcance | Impacto | Probabilidad |
|---|---|---|
| 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 Note: 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 |
Ejemplos observados
| Referencias | Descripción |
|---|---|
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). |
Mitigaciones potenciales
Phases : ImplementationEnsure that debug components are properly chained and their granularity is maintained at different authentication levels.
Métodos de detección
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.Efectividad : High
