Internal Asset Exposed to Unsafe Debug Access Level or State

CWE-1244

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.

We track 3 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 7.9.

How this weakness is prevented

  • Architecture and Design Implementation: For security-sensitive assets accessible over debug/test interfaces, only allow trusted agents.
  • Architecture and Design: Apply blinding 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.
