CVE-2025-10709 is a path traversal vulnerability identified in version 1.0 of the Four-Faith Water Conservancy Informatization Platform. The vulnerability arises from improper validation of the 'fileName' parameter in certain endpoints, specifically /history/historyDownload.do, otheruserLogin.do, and getfile. By manipulating this parameter, an attacker can traverse the file system directories beyond the intended scope, potentially accessing sensitive files on the server. This flaw can be exploited remotely without any authentication or user interaction, making it a significant risk. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity, reflecting its ease of exploitation (network attack vector, no privileges required) but limited impact confined to confidentiality with no direct impact on integrity or availability. The vendor was notified but has not responded or provided a patch, and a public exploit is available, increasing the risk of exploitation. The platform is used in water conservancy informatization, implying its deployment in critical infrastructure environments managing water resources and related data. Unauthorized access to files could lead to leakage of sensitive operational data, configuration files, or credentials, which could be leveraged for further attacks or disruption.

For European organizations, particularly those involved in water resource management, environmental monitoring, or critical infrastructure sectors, this vulnerability poses a tangible threat. Exploitation could lead to unauthorized disclosure of sensitive information, including operational data, system configurations, or user credentials, potentially enabling attackers to escalate privileges or disrupt services indirectly. Given the critical nature of water conservancy systems, any compromise could affect water distribution, monitoring, or emergency response capabilities. Although the vulnerability does not directly enable system control or denial of service, the exposure of sensitive files could facilitate subsequent attacks with more severe consequences. The lack of vendor response and public exploit availability heighten the urgency for European entities to assess their exposure and implement mitigations promptly.

European organizations using the Four-Faith Water Conservancy Informatization Platform 1.0 should immediately conduct an inventory to identify affected systems. As no official patch is available, organizations should implement compensating controls such as: 1) Restricting network access to the affected endpoints using firewalls or network segmentation to limit exposure to trusted internal networks only. 2) Employing web application firewalls (WAFs) with custom rules to detect and block path traversal patterns in the 'fileName' parameter. 3) Monitoring logs for suspicious requests targeting the vulnerable endpoints, focusing on unusual file path patterns or access attempts outside normal operations. 4) If possible, applying temporary code-level fixes or input validation to sanitize the 'fileName' parameter, preventing directory traversal sequences (e.g., ../). 5) Enhancing overall system monitoring and incident response readiness to detect and respond to exploitation attempts. Organizations should also engage with Four-Faith for updates and consider alternative solutions if remediation is delayed.
