Who should care

Organizations operating Dorsett Controls InfoScan systems in industrial control or building automation environments, particularly those with external network connectivity or insufficient network segmentation that could enable proxy-based interception of client-server communications.

Technical summary

The InfoScan client download page transmits data that can be intercepted by a man-in-the-middle proxy, exposing filenames present on the target system. This information disclosure weakness could facilitate reconnaissance for additional attacks. The vulnerability is remotely exploitable without authentication and requires no user interaction.

Defensive priority

Recommended defensive actions

  • Update InfoScan to version 1.38 or later through the System Prefs > Maintenance > Install Now workflow
  • If internet access is unavailable, download the update from the Dorsett Controls Customer Portal InfoScan Update tile and follow portal instructions
  • Review network segmentation for InfoScan systems to limit proxy-based interception opportunities
  • Monitor for unauthorized proxy usage or unexpected filename disclosure in network traffic
  • Apply CISA ICS recommended practices for defense-in-depth security controls
