Attack-Flow Graph

Executive Summary

This vulnerability involves improper handling of XML external entity references in XG VisionTerminal and XG-X VisionTerminal software by Keyence Corporation. When a user opens a specially crafted setting file, the system may disclose sensitive information stored on the device where the software is installed.

Detection Guidance

To detect this vulnerability, check if your system is running affected versions of XG VisionTerminal (Ver.5.5.0010 or earlier) or XG-X VisionTerminal (Ver.3.6.0000 or earlier). Inspect XML parsing behavior in these applications for improper external entity references. Monitor for unusual file access or sensitive data exposure when opening setting files.

Impact Analysis

If exploited, this vulnerability could allow an attacker to access sensitive system information by tricking a user into opening a malicious setting file. This may lead to unauthorized disclosure of confidential data stored on the affected system.

Compliance Impact

This vulnerability may lead to disclosure of sensitive system information, which could violate data protection requirements under GDPR and HIPAA if such data includes personal or health information. Unauthorized access to sensitive data due to improper XML external entity handling could result in non-compliance with these regulations.

Mitigation Strategies

Immediately update to XG-X VisionTerminal Ver.3.7.0000 or later. If using XG VisionTerminal, upgrade to alternative software as it is end-of-life. Avoid opening untrusted setting files until patched. Verify XML parsing configurations to block external entity references.
