Privilege escalation via reversible firmware hash
Published Jun 15, 2020 · Updated Aug 4, 2024
Privilege escalation in Intel Converged Security and Manageability Engine before 11.8.76 allows privileged local users to exploit a reversible hash. The CSME firmware uses a one-way hash that can be reversed, but Intel does not identify the affected component or operation. Local privileged access is required; the resulting exposure includes possible privilege escalation, denial of service, or information disclosure, with no public evidence of remote reachability.
