CVE-2023-31244

Arbitrary code execution via uninitialized pointer

Published Jun 6, 2023 · Updated Jan 7, 2025

Uninitialized-pointer access in Horner Automation Cscape 9.90 SP8 and Cscape EnvisionRV 4.70 allows attackers to execute code via a crafted CSP file. The file parser fails to validate supplied data before accessing an uninitialized pointer. Local delivery and user interaction are required; successful exploitation executes arbitrary code in the current process.
