Summary
OpenNHP through 1.0.2 selects its trusted-execution attestation verifier based on attacker-supplied evidence containing a test_purpose key, causing the FallbackVerifier to execute unconditionally. Attackers can bypass attestation verification by including the test_purpose key in evidence and providing enrolled measure and serial number pairs from the allowlist to gain unauthorized access.
