CVE-2022-25234

Code execution via crafted CXP file parsing

Published Mar 7, 2022 · Updated Aug 3, 2024

Out-of-bounds write in OMRON CX-Programmer 9.76.1 and earlier allows attackers to execute code by inducing a user to open a crafted CXP file. The published record identifies CXP file parsing as the input path but does not disclose the affected function, data structure, or unchecked length operation. Exploitation requires user interaction and can expose process data or execute attacker-controlled code in the user's security context.
