CVE-2026-25751 in FUXA
Summary
by MITRE • 02/06/2026
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.

The vulnerability identified as CVE-2026-25751 represents a critical information disclosure flaw within FUXA, a web-based process visualization platform widely used in industrial control systems for SCADA/HMI/Dashboard applications. This software serves as a crucial interface for monitoring and controlling industrial processes, making it a prime target for cyber threats. The vulnerability stems from inadequate access controls and improper authentication mechanisms within the application's web interface, creating an exploitable condition that allows remote attackers to bypass normal security measures. The flaw exists specifically in versions prior to 1.2.10, affecting all releases through version 1.2.9, which indicates a prolonged window of exposure for potentially critical industrial infrastructure deployments.
Technical analysis reveals that the vulnerability enables unauthenticated remote attackers to extract sensitive administrative database credentials through a flaw in the application's information disclosure mechanisms. The attack vector operates entirely over the network without requiring any prior authentication or credentials, making it particularly dangerous for industrial environments where network segmentation may not be robust. The exposed credentials provide direct access to the InfluxDB database, which serves as the backend data store for historical process information. This database contains critical operational data including process measurements, historical trends, and operational parameters that form the foundation of industrial process monitoring and control. The vulnerability's impact extends beyond simple credential theft, as it provides attackers with comprehensive access to the entire system configuration, including all database connection parameters and administrative privileges.
The operational impact of this vulnerability is severe for industrial control systems, potentially enabling attackers to perform a wide range of malicious activities that could compromise operational integrity and safety. An attacker with access to the InfluxDB database can read, modify, or delete all historical process data, which represents a significant threat to operational continuity and regulatory compliance. The ability to corrupt database content could lead to false operational readings, compromising decision-making processes and potentially causing operational failures. Furthermore, the vulnerability allows for denial of service attacks by corrupting database structures, which could render the entire visualization system inoperable. This threat is particularly concerning in industrial environments where continuous operation is critical, as the disruption could lead to production halts, safety incidents, or compliance violations. The vulnerability aligns with CWE-200 (Information Exposure) and represents a direct violation of the principle of least privilege, as the system provides excessive information access to unauthorized parties.
Mitigation strategies for this vulnerability primarily focus on immediate software updates to version 1.2.10, which contains the necessary patches to address the information disclosure flaw. Organizations should implement comprehensive network security measures including firewall rules that restrict access to FUXA services to only authorized personnel and systems. Network segmentation should be enforced to isolate industrial control systems from general network access, reducing the attack surface for remote exploitation attempts. Regular security assessments and vulnerability scanning should be conducted to identify similar flaws in industrial control system components. The remediation process should include credential rotation for all administrative accounts, particularly those associated with the InfluxDB database, to ensure that any potential compromise is contained. Additionally, organizations should implement monitoring solutions to detect unauthorized access attempts to industrial control system interfaces and establish incident response procedures specifically tailored for industrial cybersecurity threats. This vulnerability demonstrates the importance of maintaining up-to-date industrial control system software and implementing robust security practices in critical infrastructure environments.
