CVE-2024-0771Public exploit

Local memory corruption via crafted registration fields

Published Jan 21, 2024 · Updated May 8, 2025

Memory corruption in Nsasoft Product Key Explorer 4.0.9 allows local users to corrupt process memory through crafted registration data. The Registration Handler accepts crafted Name or Key field data that corrupts process memory, but public sources do not identify the faulty function or memory operation. Low-privileged local access is required, and published evidence does not establish code execution or a more specific consequence.
