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.
