Summary

Advantech ADAM-5630 versions prior to 2.5.2 contain multiple vulnerabilities allowing session hijacking, cross-site request forgery (CSRF), and denial-of-service attacks. The vulnerabilities involve improper session handling (CWE-539), missing CSRF protections (CWE-352), inadequate credential management (CWE-261), and insufficient authentication validation (CWE-306).

What this means
What could happen
An attacker with network access to the ADAM-5630 could impersonate a legitimate operator, perform unauthorized configuration changes, or disrupt data acquisition and control functions. A successful denial-of-service attack could interrupt monitoring or process control operations.
Who's at risk
Water utilities, wastewater treatment plants, and other municipal operators relying on Advantech ADAM-5630 data acquisition and remote I/O modules for process monitoring. The ADAM-5630 is commonly used to monitor sensor data and control field devices in industrial automation and environmental monitoring applications.
How it could be exploited
An attacker on the same network segment as the ADAM-5630 could trick a logged-in operator into clicking a malicious link (CSRF), craft a forged request to hijack the operator's session, or send specially formed requests to trigger a denial-of-service condition. This requires the attacker to have network access to the device and relies on user interaction (clicking a link or visiting a malicious page).
Prerequisites
  • Network access to the ADAM-5630 (same subnet or routable network segment)
  • For CSRF attacks: a legitimate user must be actively logged into the device web interface
  • For session hijacking: knowledge of or ability to intercept active session tokens
  • For DoS: ability to send repeated or malformed requests to the device
