CVE-2024-39880 (GCVE-0-2024-39880)

Vulnerability from cvelistv5 – Published: 2024-07-09 21:21 – Updated: 2025-08-27 20:42

Summary

Delta Electronics CNCSoft-G2 lacks proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. If a target visits a malicious page or opens a malicious file an attacker can leverage this vulnerability to execute code in the context of the current process.
