CVE-2025-58317

Code execution via stack buffer overflow

Published Sep 24, 2025 · Updated Sep 24, 2025

Stack-based buffer overflow in Delta Electronics CNCSoft-G2 before 2.1.0.34 allows attackers to execute code via a malicious file. The affected file-parsing path fails to validate user-supplied file data, resulting in a stack-based buffer overflow; Delta has not disclosed the specific parser or unsafe operation. A user must open the crafted file, after which code runs with the privileges of the current CNCSoft-G2 process.
