CVE-2025-8702 is a SQL Injection vulnerability identified in version 1.0 of the Wanzhou WOES Intelligent Optimization Energy Saving System, specifically within the Historical Data Query Module. The vulnerability arises from improper sanitization of the 'ObjectID' parameter in the /CommonSolution/GetVariableByOneIDNew 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 or authentication, increasing its risk profile. Although the CVSS 4.0 score rates it as medium severity (5.3), the exploitability is high due to network accessibility and low attack complexity. The impact on confidentiality, integrity, and availability is limited to low levels, suggesting that while data exposure or modification is possible, it may be constrained by the system's design or database permissions. No known exploits are currently observed in the wild, and no patches have been published yet. The vulnerability disclosure date is August 7, 2025, indicating recent discovery and potential for future exploitation if unmitigated.

For European organizations utilizing the Wanzhou WOES Intelligent Optimization Energy Saving System, this vulnerability poses a risk of unauthorized data access or manipulation within their energy management infrastructure. Given that energy optimization systems often integrate with critical building management and operational technology, exploitation could lead to inaccurate energy data reporting, disruption of energy-saving functions, or exposure of sensitive operational data. Although the direct impact on system availability appears limited, compromised data integrity could affect decision-making processes and operational efficiency. Additionally, unauthorized database access could serve as a foothold for further lateral movement within the network. The medium severity rating suggests that while the threat is not immediately catastrophic, it warrants prompt attention to prevent escalation. European organizations in sectors such as manufacturing, utilities, and large commercial real estate that deploy this system may face operational risks and potential regulatory scrutiny under data protection laws if sensitive information is exposed.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately restrict network access to the affected endpoint (/CommonSolution/GetVariableByOneIDNew) using firewalls or network segmentation to limit exposure to trusted hosts only. 2) Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection patterns targeting the 'ObjectID' parameter. 3) Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'ObjectID', to neutralize injection attempts. 4) Monitor database query logs and application logs for anomalous or unexpected queries indicative of injection attempts. 5) Engage with the vendor Wanzhou for patches or updates and apply them promptly once available. 6) As an interim measure, consider disabling or restricting the Historical Data Query Module if feasible without disrupting critical operations. 7) Perform regular security assessments and penetration tests focusing on the energy management system to identify and remediate similar vulnerabilities proactively. These steps go beyond generic advice by focusing on network-level controls, application-layer defenses, and operational monitoring tailored to this specific vulnerability and product.
