Summary

CCC Attestation SIG attested-tls-poc through commit 731ca82 fails to bind early attestation Evidence to the TLS connection. This allows attackers to relay valid Evidence from a genuine attester, and holders of an extracted attested TLS private key can replay Evidence to impersonate the attested workload.

An attacker can impersonate the attested workload and intercept data. The risk affects communication integrity and confidentiality.
