CVE-2025-8704 is a SQL Injection vulnerability identified in version 1.0 of the Wanzhou WOES Intelligent Optimization Energy Saving System, specifically within the Analysis Conclusion Query Module. The vulnerability arises from improper handling of the 'resultId' parameter in the /WEAS_AlarmResult/GetAlarmResultProcessList endpoint. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. The vulnerability does not require user interaction but does require low privileges (PR:L), indicating that some level of authentication or access is needed to exploit it. The CVSS 4.0 score is 5.3 (medium severity), reflecting moderate impact with network attack vector, low complexity, no user interaction, and partial impact on confidentiality, integrity, and availability. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The lack of available patches or mitigation guidance from the vendor further elevates the threat. Given that the system is an energy-saving optimization platform, exploitation could lead to unauthorized data disclosure, data manipulation, or disruption of energy management processes, potentially impacting operational efficiency and safety.

For European organizations utilizing the Wanzhou WOES Intelligent Optimization Energy Saving System, this vulnerability poses a risk to the confidentiality and integrity of energy management data. Successful exploitation could allow attackers to extract sensitive operational data, manipulate alarm results, or disrupt energy optimization processes. This could lead to operational inefficiencies, increased energy costs, or even safety hazards if critical alarms are suppressed or falsified. Organizations in sectors such as manufacturing, utilities, and smart building management that rely on this system could face operational disruptions and compliance issues, especially under strict EU data protection regulations like GDPR. Additionally, compromised systems could serve as footholds for further network intrusion or lateral movement within critical infrastructure environments.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the vulnerable endpoint (/WEAS_AlarmResult/GetAlarmResultProcessList) via network segmentation and firewall rules to trusted IPs only; 2) Implementing Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'resultId' parameter; 3) Enforcing strict authentication and authorization policies to limit access to the system; 4) Conducting thorough input validation and sanitization at the application layer if possible; 5) Monitoring logs for anomalous queries or repeated access attempts to the vulnerable endpoint; 6) Planning for an upgrade or patch deployment once the vendor releases a fix; and 7) Performing regular security assessments and penetration tests focused on this system to detect exploitation attempts early.
