CVE-2025-22881

Code execution via unchecked heap-buffer copy

Published Feb 26, 2025 · Updated Feb 26, 2025

Heap-based buffer overflow in Delta Electronics CNCSoft-G2 2.1.0.10 and earlier allows remote attackers to execute code via a crafted file. Its file-parsing logic copies attacker-controlled data into a fixed-length heap buffer without first validating the data length. Exploitation requires a target to visit a malicious page or open a malicious file, and resulting code runs in the context of the current process.
