Credential disclosure via unencrypted web sessions
Published Oct 31, 2025 · Updated Oct 31, 2025
Cleartext transmission in CIRCUTOR TCPRS1+ firmware 1.0.14 allows man-in-the-middle attackers to read credentials and device data over HTTP. The embedded web server carries login and management exchanges over unencrypted HTTP, exposing usernames, passwords, configuration, and operational values in readable packets. Exploitation requires a legitimate user to access the web interface while man-in-the-middle attackers can observe an intermediate network interface; captured credentials enable later device access.
