Remote secret disclosure via covert timing channel
Published Jul 11, 2022 · Updated Sep 17, 2024
Observable timing discrepancy in Dell BSAFE Crypto-C Micro Edition before 4.1.5 allows remote attackers to disclose sensitive data. Dell identifies only a covert timing channel in proprietary cryptographic code and has not disclosed the affected API or secret-dependent operation. Remote exploitation is unauthenticated but requires high-complexity timing analysis; reported effects are limited to confidential-data exposure.
