Security readout for executives and security teams
Plain-English summary
FR Configurator2 can be tricked into reading local files when a user opens a malicious project or template file. This affects Version 1.16S and prior. The main business concern is exposure of sensitive files on engineering workstations, not a remotely triggered compromise based on the provided evidence.
Executive priority
Treat this as a targeted engineering-workstation data exposure risk. Prioritize inventory and vendor-guided remediation where FR Configurator2 is used, especially in operational technology environments that exchange project files externally.
Technical view
CVE-2019-10976 is a CWE-611 XML External Entity issue in Mitsubishi Electric FR Configurator2. Unsanitized input reaches the XML parser while parsing .frc2 project or template files. Opening a crafted file may allow arbitrary local file read. No CVSS score or vendor fix version is included in the provided bundle.
Likely exposure
Organizations using Mitsubishi Electric FR Configurator2 Version 1.16S or earlier are exposed, especially where .frc2 files are received from external parties, shared across teams, or opened on engineering workstations containing sensitive data.
Exploitation context
The provided sources describe user-assisted exploitation through opening a malicious .frc2 file. The bundle does not show CISA KEV listing, active exploitation, public exploit use, or remote unauthenticated exploitation.
Researcher notes
Evidence supports an XXE-style arbitrary file read triggered during .frc2 XML parsing. The source bundle lacks CVSS details, exploit maturity, patch version, and deeper parser behavior. Avoid assuming broader product impact beyond FR Configurator2 Version 1.16S and prior.
Mitigation direction
- Identify FR Configurator2 installations and versions across engineering workstations.
- Check Mitsubishi Electric and CISA advisory guidance for supported remediation.
- Do not open .frc2 files from untrusted or unexpected sources.
- Use least-privilege accounts for engineering workstation activity.
- Keep project and template file exchange within trusted channels.
Validation and detection
- Confirm whether FR Configurator2 Version 1.16S or earlier is installed.
- Review how .frc2 project and template files enter the organization.
- Verify users know to treat unexpected .frc2 files as untrusted.
- Check whether vendor guidance has been applied or formally tracked.
- Review workstation data exposure if affected users opened suspicious files.

Improper Restriction of XML External Entity Reference
Improper Restriction of XML External Entity Reference represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
