Summary
ARDEREG Sistemas SCADA versions 2.203 and earlier contain a SQL injection vulnerability (CWE-89) that allows an attacker to manipulate SQL query logic through unsanitized input. Successful exploitation could allow unauthorized extraction of sensitive database information and execution of unauthorized actions within the database, potentially affecting operational control and decision-making. The vendor is aware of the issue but has not released a patch and recommends network segmentation, security assessments, and developer training as mitigations.
What this means
What could happen
An attacker with network access to the SCADA database could extract sensitive operational data, modify control logic, or disrupt system availability by injecting malicious SQL commands. This could enable unauthorized changes to setpoints, alarms, or process parameters.
Who's at risk
Energy sector operators running ARDEREG Sistemas SCADA version 2.203 or earlier are affected. This includes utilities managing power generation, transmission, and distribution systems that rely on this SCADA platform for real-time monitoring and control of critical infrastructure.
How it could be exploited
An attacker sends crafted SQL injection payloads to the SCADA system's database interface. If the application does not properly validate or sanitize user input before constructing SQL queries, the attacker can manipulate the query logic to extract data, modify records, or execute administrative commands on the database.
Prerequisites
- Network access to the SCADA system's database interface or application port
- The SCADA system version is 2.203 or earlier
- Input validation is not properly implemented or is bypassable

Remediation & Mitigation
0/6
Do now
0/2HARDENINGImplement network segmentation to isolate the SCADA system from business networks and the Internet. Ensure the system is not directly accessible from external networks.
HARDENINGDeploy a firewall with strict access control rules allowing only authorized engineering workstations and administrators to reach the SCADA database ports.
Schedule — requires maintenance window
0/1Patching may require device reboot — plan for process interruption
HARDENINGConduct a security assessment and penetration testing of the SCADA system to identify any existing SQL injection vulnerabilities or misconfigurations.
Mitigations - no patch available
0/3Sistemas SCADA: <= 2.203 has reached End of Life. The vendor will not release a patch. Apply the following compensating controls:
HARDENINGProvide secure coding training and developer security awareness to emphasize input validation, parameterized queries, and secure database interaction practices.
HARDENINGDevelop and maintain an incident response plan that addresses SQL injection and database compromise scenarios, including containment and recovery procedures.
HARDENINGEvaluate vendor security practices and supply chain security controls to ensure new versions and updates do not introduce similar vulnerabilities.
