CWE-1244Internal Asset Exposed to Unsafe Debug Access Level or State

Description

The product uses physical debug or test interfaces with support for multiple access levels, but it assigns the wrong debug access level to an internal asset, providing unintended access to the asset from untrusted debug agents.

[object Object]

Common consequences

• Confidentiality→Read Memory
  If a protection mechanism does not ensure that internal assets have the correct debug access level during each boot stage or change in system state, an attacker could obtain sensitive information from the internal asset using a debugger.
• Integrity→Modify Memory
• Authorization,Access Control→Gain Privileges or Assume Identity,Bypass Protection Mechanism

Potential mitigations

• Architecture and Design,Implementation
  [object Object]
• Architecture and Design
  Apply blinding [REF-1219] or masking techniques in strategic areas.
• Implementation
  Add shielding or tamper-resistant protections to the device, which increases the difficulty and cost for accessing debug/test interfaces.
