Summary

The Advantech ADAM-5630 remote terminal unit contains vulnerabilities in session management and cross-site request forgery (CSRF) protections that allow an attacker with network access to hijack authenticated user sessions. These vulnerabilities affect ADAM-5630 devices running firmware versions below 2.5.2. Successful exploitation could allow an attacker to perform unauthorized actions on the device or cause denial-of-service conditions affecting monitoring and control functions.

What this means
What could happen
An attacker with network access to the ADAM-5630 could hijack a legitimate user's session or perform unauthorized actions on the device via cross-site request forgery, potentially disrupting monitoring and control functions for connected equipment.
Who's at risk
This affects operators of Advantech ADAM-5630 remote terminal units (RTUs) and other monitoring/data acquisition devices using this platform. Typical users include water treatment facilities, power distribution operators, and industrial facilities using ADAM-5630 for sensor data collection and equipment control.
How it could be exploited
An attacker must be on the same network segment as the ADAM-5630 and trick a logged-in user into clicking a malicious link or visiting a crafted webpage. The attacker can then execute commands or access data as that user without their knowledge. The vulnerability requires user interaction but no prior authentication by the attacker.
Prerequisites
  • Network access to the ADAM-5630 on the same local network or connected network segment
  • A legitimate user must be logged into the device's web interface
  • User must click a malicious link or visit a crafted webpage while authenticated
