High-Assurance Remediation of CVE-2024-12248

og:description

This post demonstrates how CodeHawk enables high-assurance patching of vulnerabilities in stripped binaries without manual binary editing. We detail the remediation of CVE 2024-12248 in the Contec CMS 8000 Patient Monitor by lifting the firmware to semantically validated C code, applying idiomatic fixes directly on the C code, and automatically synthesizing precise binary-level patches. We evaluate two patch strategies, highlighting the trade-off between broader input filtering and minimal behavioral change, with CodeHawk proving that both eliminate the buffer-overflow vulnerability.
