CVE-2025-22880

Code execution via DPAX heap buffer overflow

Published Feb 7, 2025 · Updated Feb 7, 2025

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