CVE-2025-8703 is a medium-severity SQL Injection vulnerability identified in version 1.0 of the Wanzhou WOES Intelligent Optimization Energy Saving System, specifically within the Environmental Real-Time Data Module. The vulnerability exists in the /WEAS_HomePage/GetAreaTrendChartData endpoint, where the 'energyId' parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This flaw can be exploited remotely without requiring user interaction or elevated privileges, as indicated by the CVSS vector (AV:N/AC:L/PR:L/UI:N). Successful exploitation could lead to unauthorized access or manipulation of the backend database, potentially compromising data confidentiality, integrity, and availability. Although the CVSS score is 5.3 (medium), the attack vector is network-based with low complexity and no user interaction, which increases the risk profile. No public exploits have been reported in the wild yet, and no patches have been published. The vulnerability disclosure date is August 8, 2025. The lack of authentication requirement (PR:L indicates low privileges needed) suggests that an attacker with minimal access could leverage this flaw, possibly escalating privileges or extracting sensitive operational data from the energy management system. The WOES system is used for intelligent optimization and energy saving, implying that compromised data or system manipulation could disrupt energy management processes or leak sensitive environmental data.

For European organizations utilizing the Wanzhou WOES Intelligent Optimization Energy Saving System, this vulnerability could have significant operational and security impacts. Energy management systems are critical infrastructure components, and exploitation could lead to unauthorized data disclosure, manipulation of energy consumption data, or disruption of energy optimization processes. This may result in financial losses due to inefficient energy usage, regulatory non-compliance, or damage to reputation. Additionally, attackers could leverage the SQL injection to pivot within the network, potentially accessing other critical systems. Given the increasing emphasis on energy efficiency and sustainability across Europe, any compromise of such systems could hinder organizational goals and national energy policies. The medium severity rating suggests moderate risk, but the potential for data integrity issues and operational disruption elevates the concern for organizations relying on this system for real-time environmental data and energy optimization.

Organizations should immediately audit their deployments of the Wanzhou WOES Intelligent Optimization Energy Saving System to identify affected versions (1.0). In absence of an official patch, implement web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'energyId' parameter in the /WEAS_HomePage/GetAreaTrendChartData endpoint. Conduct thorough input validation and sanitization on all user-supplied parameters, especially those interacting with databases. Restrict access to the vulnerable endpoint through network segmentation and access control lists, limiting exposure to trusted internal networks only. Monitor logs for suspicious query patterns indicative of SQL injection attempts. Engage with the vendor for timely patch releases and apply updates as soon as they become available. Additionally, perform regular security assessments and penetration tests focusing on injection flaws within energy management systems. Implement database-level protections such as least privilege for database accounts used by the application to minimize impact if exploited.
