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 manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. The vulnerability is remotely exploitable without requiring user interaction or elevated privileges, which increases its risk profile. The disclosed CVSS 4.0 score is 5.3 (medium severity), reflecting the fact that while the attack vector is network-based and requires no user interaction, it does require low privileges and the impact on confidentiality, integrity, and availability is limited to low levels. No known exploits are currently active in the wild, and no patches have been published yet. However, public disclosure of the exploit details increases the likelihood of exploitation attempts. The vulnerability could allow attackers to extract sensitive data, corrupt or delete records, or disrupt system operations, depending on the database permissions and system architecture. Given the system's role in energy optimization and saving, exploitation could also indirectly impact operational efficiency and energy management processes.

For European organizations using the Wanzhou WOES Intelligent Optimization Energy Saving System, this vulnerability poses risks to the confidentiality and integrity of energy management data. Unauthorized data access could expose sensitive operational metrics or proprietary optimization algorithms. Data manipulation could lead to incorrect energy consumption reporting or suboptimal system behavior, potentially increasing costs or causing operational disruptions. While the direct availability impact is low, indirect effects on energy systems could have broader operational consequences. Organizations in critical infrastructure sectors, such as utilities or manufacturing, that rely on this system for energy optimization may face increased risk of targeted attacks aiming to disrupt energy efficiency or gather intelligence. The medium severity rating suggests that while the threat is notable, it may not lead to catastrophic failures without additional attack vectors or privilege escalation. Nonetheless, the public disclosure and remote exploitability necessitate prompt attention to prevent exploitation.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include: 1) Applying strict input validation and sanitization on the 'resultId' parameter at the web application firewall (WAF) or reverse proxy level to block malicious SQL payloads. 2) Restricting database user permissions associated with the WOES system to the minimum necessary, preventing unauthorized data modification or extraction. 3) Monitoring and logging all access to the /WEAS_AlarmResult/GetAlarmResultProcessList endpoint for unusual patterns indicative of SQL injection attempts. 4) Employing network segmentation to isolate the WOES system from broader corporate networks, limiting lateral movement if compromised. 5) Engaging with the vendor to obtain patches or updates as soon as they become available. 6) Conducting regular security assessments and penetration tests focused on injection vulnerabilities. 7) Educating system administrators about the vulnerability and recommended response procedures to ensure rapid detection and response.
