CVE-2025-22880, published on 2025-02-07, is a heap-based buffer overflow vulnerability in Delta Electronics' CNCSoft-G2 software. The flaw stems from a lack of proper validation of the length of user-supplied data prior to copying it into a fixed-length heap-based buffer, as classified under CWE-122. It carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

A local attacker can exploit this vulnerability with low complexity and no privileges required by tricking a user into visiting a malicious web page or opening a malicious file. Successful exploitation enables arbitrary code execution in the context of the current process, resulting in high impacts to confidentiality, integrity, and availability.

Delta Electronics has published security advisory PCSA-2025-00002, available at https://filecenter.deltaww.com/news/download/doc/Delta-PCSA-2025-00002_CNCSoft-G2%20-%20Heap-based%20Buffer%20Overflow_v1.pdf, which addresses the vulnerability.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including fuzzing and memory-error detectors) can discover heap overflows after they have been coded.

Input validation enforces bounds checking on data written to heap buffers, directly stopping the overflow condition from being introduced.

Security engineering principles require use of memory-safe constructs and bounds-checked allocation routines that avoid introducing heap overflows.

Memory-protection mechanisms limit the ability of a heap overflow to execute attacker-controlled code or corrupt adjacent structures.
