CWE-393Return of Wrong Status Code CWE-637Unnecessary Complexity in Protection Mechanism (Not Using 'Economy of Mechanism')

Description

Szafir SDK returns a success status code from the cryptographic digital signature verification process (i.e. /VerifyingTaskItem/Signature/VerificationResult/Result/@code == 0, "Positively verified") even when the trust status of the signer's certificate could not be established (i.e. /VerifyingTaskItem/Signature/VerificationResult/SigningCertificate/@certificateType == "nondetermined"). This causes consuming applications to incorrectly treat the signature as valid despite an unverified certificate chain, enabling authentication bypass and user impersonation. This issue was fixed in version 463.
