Quick assessment

Affected
OpenNHP opennhp
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenNHP 版本 1.0.2 及更早版本在根据攻击者提供的证据（其中包含 test_purpose 键）选择可信执行环境（TEE）证明验证器时，会导致 FallbackVerifier（回退验证器）无条件执行。攻击者通过在证据中包含 test_purpose 键，并提供来自允许列表的已注册度量值（measure）和序列号（serial number）对，即可绕过证明验证，从而获得未经授权的访问权限。
