Delta Electronics CNCSoft-G2 DPAX File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability (CVE-2025-22880)

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Electronics CNCSoft-G2.

User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of DPAX files.

The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer.

An attacker can leverage this vulnerability to execute code in the context of the current process.
