Enclave-secret disclosure via unchecked pointer dereferences
Published Dec 30, 2023 · Updated Aug 3, 2024
Information disclosure in Scontain SCONE before 5.8.0 allows local users to read enclave secrets through crafted pointer inputs. The __scone_dispatch runtime dereferences attacker-tainted pointers without verifying that they remain outside protected enclave memory. A user able to invoke Intel SGX enclave entry points can exploit eight unconstrained pointer dereferences and two outside-enclave reads.
