description

Versions of enclave-os-virtual before tdx-v0.2.43 and tdx-gpu-v0.6.27 do not bind RA-TLS attestation evidence to the active TLS session. An attacker who obtains an enclave TLS private key may cause a relying party to accept an attacker-terminated connection as the attested enclave.

mitigation

Upgrade the applicable release track to tdx-v0.2.43 or later, or to tdx-gpu-v0.6.27 or later. Protect and rotate enclave TLS private keys as part of the update.

fixed in tdx-v0.2.43, tdx-gpu-v0.6.27

outcome

Mechanism verified: the exploit fired on the vulnerable build and stayed silent on the patched one, but the server it ran against was ours, so no check ships for it.
