FUXA is an open-source automation tool used in industrial control systems and SCADA applications for monitoring, controlling, and configuring devices. Developed and maintained by FRANGOTEAM, it is popular among individuals and companies implementing IoT solutions. FUXA allows real-time data access and visualization, making it essential for efficient industrial operation management. It supports customization and plugin integrations, providing flexibility in various applications. User-friendly interfaces and comprehensive documentation have contributed to its wide adoption. The software continuously updates to enhance features and security.
The SQL Injection vulnerability in FUXA <= 1.1.12 arises due to insufficient input sanitization in the "/api/signin" endpoint. This unmitigated flaw allows attackers to inject and execute arbitrary SQL commands on the database. Such vulnerabilities occur when unsanitized inputs are accepted and improperly executed by the database server. Attackers exploit weaknesses like these to bypass authentication and manipulate sensitive data. SQL Injection is a critical vulnerability that can lead to severe consequences for users and organizations. Addressing this flaw promptly is crucial to maintaining system integrity and security.
The vulnerability is primarily located in the '/api/signin' endpoint of the FUXA application. Attackers can leverage crafted payloads to substantially alter SQL queries executed by the application. For instance, the input fields for username and password are manipulated with `' OR '1'='1` logic to always succeed authentication checks. This technical flaw exposes the underlying database logic to manipulation through unexpected SQL commands. Exploiting this vulnerability typically allows access to unauthorized data and database manipulation. The existence of such SQL injection points requires immediate remediation to prevent unauthorized access and data breaches.
Exploiting this vulnerability could allow attackers unauthorized access to database information. An attacker could retrieve, modify, or delete critical data, undermining system operations. Manipulating SQL commands can result in the exposure of sensitive data such as usernames and passwords. Once breached, an attacker might further exploit the system for lateral movements or launching additional attacks. Beyond data theft, persistent manipulations could lead to permanent unauthorized access, threatening operational integrity. It is critical to address this vulnerability to sustain system security and limit potential damages from exploitation.
