Detailsinfo

A vulnerability, which was classified as critical, has been found in Privasys enclave-os-mini up to wasm-v0.39.x. Affected by this issue is an unknown functionality of the component RA-TLS. The manipulation with an unknown input leads to a session fixiation vulnerability. Using CWE to declare the problem leads to CWE-384. Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Enclave OS Mini is a Rust-based runtime for confidential applications inside Intel SGX enclaves. Prior to wasm-v0.40.0, the SGX runtime's RA-TLS challenge certificate path placed the certificate public-key hash and client nonce in quote ReportData but omitted a value bound to the active TLS session. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing a relying party to accept an attacker-terminated connection as the attested enclave. This issue is fixed in wasm-v0.40.0.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-108265 since 10/09/2026. The exploitation is known to be easy. The attack may be launched remotely. The technical details are unknown and an exploit is not available.
