Weakness Name
Improper Access Control for Register Interface
Description
The product uses memory-mapped I/O registers that act as an interface to hardware functionality from software, but there is improper access control to those registers.
Software commonly accesses peripherals in a System-on-Chip (SoC) or other device through a memory-mapped register interface. Malicious software could tamper with any security-critical hardware data that is accessible directly or indirectly through the register interface, which could lead to a loss of confidentiality and integrity.
Common Consequences
Scope: Confidentiality, Integrity
Impact: Read Memory, Read Application Data, Modify Memory, Modify Application Data, Gain Privileges or Assume Identity, Bypass Protection Mechanism, Unexpected State, Alter Execution Logic
Notes: Confidentiality of hardware assets may be violated if the protected information can be read out by software through the register interface. Registers storing security state, settings, other security-critical data may be corruptible by software without correctly implemented protections.
