Name of the Vulnerable Software and Affected Versions
Enclave OS Virtual versions prior to tdx-v0.2.43
Enclave OS Virtual versions prior to tdx-gpu-v0.6.27
Description
The TDX/GPU RA-TLS certificate issuer places the certificate public-key hash and client nonce in the quote
ReportData but fails to include a value bound to the active TLS session. This allows an attacker with an enclave TLS private key to relay a genuine quote to a different connection, leading a relying party to mistakenly accept an attacker-terminated connection as the attested enclave.Recommendations
Update Enclave OS Virtual to version tdx-v0.2.43 or later.
Update Enclave OS Virtual to version tdx-gpu-v0.6.27 or later.
