Vendor Patch Analysis and Verification of CVE-2024-12248

og:description

This post demonstrates how CodeHawk enables rapid analysis and verification of opaque vendor firmware patches. We apply CodeHawk’s lifting and static analysis capabilities to assess Contec’s patch for CVE-2024-12248 in the CMS 8000 Patient Monitor, confirming, via a strong, automated verification, that the critical buffer overflow is fixed and revealing additional undocumented changes. By structurally comparing the original and patched binaries, we identify added functionality and a potential vulnerability, highlighting the need for independent validation of vendor updates in safety-critical environments.
