CWE-1222

Insufficient Granularity of Address Regions Protected by Register Locks

The product defines a large address region protected from modification by the same register lock control bit. This results in a conflict between the functional requirement that some addresses need to be writable by software during operation and the security requirement that the system configuration lock bit must be set during the boot process.

Mitigation

Phase: Architecture and Design

Description:

  • The defining of protected locked registers should be reviewed or tested early in the design phase with software teams to ensure software flows are not blocked by the security locks.
  • As an alternative to using register lock control bits and fixed access control regions, the hardware design could use programmable security access control configuration so that device trusted firmware can configure and change the protected regions based on software usage and security models.
CAPEC-679: Exploitation of Improperly Configured or Implemented Memory Protections

An adversary takes advantage of missing or incorrectly configured access control within memory to read/write data or inject malicious code into said memory.
