Can you explain this vulnerability to me?
CVE-2026-25752 is a critical authorization bypass vulnerability in FUXA, a web-based Process Visualization software used in SCADA/HMI/Dashboard environments.
This flaw allows an unauthenticated remote attacker to modify device tags via WebSockets without any privilege or user interaction, effectively bypassing role-based access controls.
Because of this, attackers can overwrite arbitrary device tags or disable communication drivers, potentially manipulating physical processes and disconnected devices from the Human-Machine Interface (HMI).
The vulnerability affects FUXA versions up to 1.2.9 and has been patched in version 1.2.10.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to unauthorized modification of device tags and disabling of communication drivers in ICS/SCADA environments.
This can allow attackers to manipulate physical processes and devices remotely, potentially causing disruption or damage to industrial control systems.
The impacts include high integrity and availability risks, meaning critical data can be altered and services can be disrupted.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?

What immediate steps should I take to mitigate this vulnerability?
The vulnerability in FUXA allows unauthenticated remote attackers to bypass authorization and modify device tags via WebSockets, which can lead to manipulation of physical processes and disruption of ICS/SCADA environments.
To mitigate this vulnerability immediately, users should update FUXA to version 1.2.10 or later, where the issue has been patched.
Since the vulnerability affects all deployments regardless of the runtime setting `secureEnabled`, relying on configuration alone is insufficient.
