Reаd the cаse belоw аnd select the mоre accurate answer that describes which security design principle (just оne) was violated. The Advanced eXtensible Interface (AXI) is an on-chip communication bus protocol and is part of the Advanced Microcontroller Bus Architecture specification (AMBA). AXI is a burst-based protocol, meaning that there may be multiple data transfers (or beats) for a single request. This makes it worthwhile in cases where it is necessary to transfer large amounts of data from or to a specific pattern of addresses.     Within the AXI node interface wrapper module in the RISC-V AXI module, an access control mechanism is employed to regulate the access of different privileged users to peripherals. The AXI ensures that only users with appropriate privileges can access specific peripherals. For instance, a ROM module is accessible exclusively with Machine privilege, and AXI enforces that those users attempting to read data from the ROM must possess Machine privilege; otherwise, access to the ROM is denied. The access control information and configurations are stored in a ROM. However, while assigning distinct privileges to AXI manager and subordinates, both the Platform-Level Interrupt Controller Specification (PLIC) and the Core-local Interrupt Controller (CLINT) (which are peripheral numbers 6 and 7, respectively) utilize the same access control configuration. This common configuration diminishes the granularity of the AXI access control mechanism. In certain situations, granting higher privileges for accessing the PLIC might be necessary than those required for accessing the CLINT. Unfortunately, this differentiation is overlooked, allowing attackers to access the PLIC with lower privileges than intended. Consequently, unprivileged code can be read and written to the PLIC even when it was not intended to do so. In the worst-case scenario, the attacker could manipulate interrupt priorities, potentially modifying the system's behavior or availability.
