CWE-1233 类漏洞列表 2

CWE-1233 类弱点 2 条 CVE 漏洞汇总，含 AI 中文分析。

MITRE CWE 官方描述
The product uses a register lock bit protection mechanism, but it does not ensure that the lock bit prevents modification of system registers or controls that perform changes to important hardware system configuration. Integrated circuits and hardware intellectual properties (IPs) might provide device configuration controls that need to be programmed after device power reset by a trusted firmware or software module, commonly set by BIOS/bootloader. After reset, there can be an expectation that the controls cannot be used to perform any further modification. This behavior is commonly implemented using a trusted lock bit, which can be set to disable writes to a protected set of registers or address regions. The lock protection is intended to prevent modification of certain system configuration (e.g., memory/memory protection unit configuration). However, if the lock bit does not effectively write-protect all system registers or controls that could modify the protected system configuration, then an adversary may be able to use software to access the registers/controls and modify the protected hardware configuration.
常见影响 (1)
Access ControlModify Memory
System Configuration protected by the lock bit can be modified even when the lock is set.
缓解措施 (1)
Architecture and Design, Implementation, TestingSecurity lock bit protections must be reviewed for design inconsistency and common weaknesses. Security lock programming flow and lock properties must be tested in pre-silicon and post-silicon testing.

Consider the example design below for a digital thermal sensor that detects overheating of the silicon and triggers system shutdown. The system critical temperature limit (CRITICAL_TEMP_LIMIT) and thermal sensor calibration (TEMP_SENSOR_CALIB) data have to be programmed by the firmware.
Register Field description CRITICAL_TEMP_LIMIT [31:8] Reserved field; Read only; Default 0 [7:0] Critical temp 0-255 Centigrade; Read-write-lock; Default 125 TEMP_SENSOR_CALIB [31:0] Thermal sensor calibration data. A slope value used to map sensor reading to a degree Centigrade. Read-write; Default 25 TEMP_SENSOR_LOCK [31:1] Reserved field; Read only; Default 0 [0] Lock bit, locks CRITICAL_TEMP_LIMIT register; Write-1-once; Default 0 TEMP_HW_SHUTDOWN [31:2] Reserved field; Read only; Default 0 [1] Enable hardware shutdown on a critical temperature detection; Read-write; Default 0 CURRENT_TEMP

Change TEMP_HW_SHUTDOWN and TEMP_SENSOR_CALIB controls to be locked by TEMP_SENSOR_LOCK. TEMP_SENSOR_CALIB [31:0] Thermal sensor calibration data. A slope value used to map sensor reading to a degree Centigrade. Read-write-Lock; Default 25; Locked by TEMP_SENSOR_LOCK bit[0] TEMP_HW_SHUTDOWN [31:2] Reserved field; Read only; Default 0 [1] Enable hardware shutdown on critical temperature detection; Read-write-Lock; Default 0; Locked by TEMP_SENSOR_LOCK bit[0]
