CVE-2025-22881 (GCVE-0-2025-22881)

Vulnerability from cvelistv5 – Published: 2025-02-26 01:44 – Updated: 2025-02-26 15:43

Title

Heap-based Buffer Overflow in CNCSoft-G2

Summary

Delta Electronics CNCSoft-G2 lacks proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-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.

Severity

8.4 (High)
