CVE-2023-36199Public exploitNetwork attack vector

Service crash via uninitialized curve pointer

Published Aug 25, 2023 · Updated Oct 3, 2024

NULL pointer dereference in SKALE Network SGXWallet 1.9.0 and earlier allows attackers to crash the service via an early key-generation call. The trustedGenerateEcdsaKey enclave call dereferences the global curve pointer when invoked before trustedEnclaveInit initializes it. The public issue does not explain how an attacker reaches this call order through the certificate-authenticated network service; a successful trigger interrupts wallet key generation and signing.
