Description Preview
A buffer overflow vulnerability exists in Yokogawa WideField3 software versions R1.01 through R4.03. When a user loads a specially crafted malicious project file, a buffer overflow condition can be triggered, potentially allowing arbitrary code execution with the privileges of the application.
Overview
This vulnerability (CVE-2020-16232) affects Yokogawa WideField3, which is engineering software used for programming and configuring Yokogawa controllers in industrial environments. The vulnerability is classified as CWE-120 (Classic Buffer Overflow). When exploited, an attacker could craft a malicious project file that, when opened by a user of the WideField3 software, would cause a buffer overflow. This could potentially lead to code execution, application crashes, or other unintended behavior. The vulnerability requires user interaction to exploit, as the malicious file must be opened within the application.
Remediation
Users of Yokogawa WideField3 should implement the following remediation steps:
- Update to the latest version of WideField3 software that addresses this vulnerability.
- Exercise caution when opening project files from untrusted sources.
- Implement the principle of least privilege for users working with WideField3 software.
- Consider network segmentation to isolate engineering workstations running WideField3.
- Follow Yokogawa's security advisories and recommended security practices.
- Verify the authenticity and integrity of project files before opening them in WideField3.
