Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Training on secure data handling discourages cleartext storage of sensitive information.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Unauthenticated remote exploit of public-facing FUXA web app directly enables T1190; cleartext credential disclosure enables T1552 for subsequent DB access.
NVD Description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An information disclosure vulnerability in FUXA allows an unauthenticated, remote attacker to retrieve sensitive administrative database credentials. Exploitation allows an unauthenticated, remote attacker to obtain the full system configuration, including administrative credentials…

for the InfluxDB database. Possession of these credentials may allow an attacker to authenticate directly to the database service, enabling them to read, modify, or delete all historical process data, or perform a Denial of Service by corrupting the database. This affects FUXA through version 1.2.9. This issue has been patched in FUXA version 1.2.10.
Deeper analysisAI
CVE-2026-25751 is an information disclosure vulnerability in FUXA, an open-source web-based Process Visualization (SCADA/HMI/Dashboard) software. The flaw allows an unauthenticated remote attacker to retrieve sensitive administrative database credentials, exposing the full system configuration, including credentials for the InfluxDB database. It affects all versions of FUXA through 1.2.9 and has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), linked to CWE-306 (Missing Authentication for Critical Function) and CWE-312 (Cleartext Storage of Sensitive Information).
An unauthenticated attacker with network access can exploit this vulnerability remotely with low complexity, without requiring user interaction or privileges. Successful exploitation grants the full system configuration and InfluxDB administrative credentials, enabling direct authentication to the database service. This allows the attacker to read, modify, or delete all historical process data, or conduct a denial-of-service by corrupting the database.
The issue has been addressed in FUXA version 1.2.10, as detailed in the project's GitHub release notes (https://github.com/frangoteam/FUXA/releases/tag/v1.2.10) and security advisory (https://github.com/frangoteam/FUXA/security/advisories/GHSA-c5gq-4h56-4mmx). Security practitioners should upgrade to the patched version and review exposed FUXA instances for potential credential compromise.
