Description Preview
A use-after-free vulnerability (CWE-416) exists in CX-Programmer version 9.79 and earlier. When a user opens a specially crafted CXP file, the application attempts to access memory after it has been freed, which could lead to information disclosure or arbitrary code execution. This vulnerability is distinct from similar issues tracked as CVE-2023-22317 and CVE-2023-22314. An attacker could exploit this vulnerability by convincing a user to open a malicious CXP file, potentially gaining control of the affected system with the privileges of the user running the application.
Overview
CX-Programmer is a programming software used for Omron PLCs (Programmable Logic Controllers). The vulnerability exists in version 9.79 and earlier versions of the software. The use-after-free vulnerability occurs when the application incorrectly manages memory, attempting to use memory that has already been freed. This can lead to unpredictable behavior, including information disclosure or arbitrary code execution. The vulnerability is particularly concerning in industrial environments where CX-Programmer might be used to program critical control systems. An attacker could craft a malicious CXP project file that, when opened by a user, triggers the vulnerability.
Remediation
Users should implement the following remediation steps:
- Update CX-Programmer to a version newer than 9.79 if available.
- If updates are not available, consider implementing application isolation techniques such as running the software in a virtual environment.
- Exercise caution when opening CXP files from untrusted sources.
- Implement the principle of least privilege for users who have access to CX-Programmer.
- Use network segmentation to isolate engineering workstations running CX-Programmer from other networks.
- Monitor systems for suspicious activities that might indicate exploitation attempts.
- Contact the vendor (Omron) for specific patching information if not publicly available.
