Improper authorization control for web services In fuxa-server
Description
FUXA Unauthenticated Remote Arbitrary Device Tag Write
Summary
Description An authorization bypass vulnerability in FUXA allows an unauthenticated, remote attacker to modify device tags via WebSockets. This affects FUXA through version 1.2.9. This issue has been patched in FUXA version 1.2.10.
Impact
This affects all deployments, including those with runtime.settings.secureEnabled set to true.
Exploitation allows an unauthenticated, remote attacker to bypass role-based access controls and overwrite arbitrary device tags or disable communication drivers, exposing connected ICS/SCADA environments to follow-on actions. This may allow an attacker to manipulate physical processes and disconnected devices from the HMI.
Patches
This issue has been patched in FUXA version 1.2.10. Users are strongly encouraged to update to the latest available release.
Mitigation
Update Impact
Minimal update. May introduce new vulnerabilities or breaking changes.
