CVE-2025-11018 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' argument in a specific endpoint path involving /sysRole/index.do/../../generalReport/download.do;usrlogout.do.do. This flaw allows an unauthenticated remote attacker to manipulate the fileName parameter to traverse directories outside the intended scope, potentially accessing arbitrary files on the server's filesystem. The vulnerability does not require any privileges or user interaction, making it remotely exploitable over the network. Although the vendor was notified early, no patch or response has been provided, and a public exploit has been published, increasing the risk of exploitation. The CVSS v4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, no privileges or user interaction required, and limited impact confined to confidentiality (read access to files). There is no indication that integrity or availability are affected. The vulnerability is specific to version 1.0 of the product, which is used in water conservancy informatization, likely involving critical infrastructure management and monitoring systems. Given the nature of path traversal, attackers could access sensitive configuration files, credentials, or other critical data stored on the server, which could lead to further compromise or information leakage.

For European organizations, especially those involved in water resource management, environmental monitoring, or critical infrastructure sectors, this vulnerability poses a significant risk. Unauthorized access to sensitive files could expose operational data, system configurations, or credentials, potentially enabling attackers to escalate privileges or disrupt water conservancy operations. Such disruptions could affect water supply management, flood control, or irrigation systems, leading to operational downtime or safety hazards. Additionally, exposure of sensitive data could result in regulatory non-compliance under GDPR if personal or operational data is leaked. The lack of vendor response and the availability of a public exploit increase the likelihood of targeted attacks against organizations using this platform in Europe. Since water conservancy is a critical infrastructure sector, exploitation could have cascading effects on public safety and environmental management.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include restricting network access to the affected platform using firewalls or network segmentation to limit exposure to trusted internal users only. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block path traversal patterns in HTTP requests targeting the vulnerable endpoints. Conduct thorough audits of the platform's file system permissions to minimize accessible sensitive files and ensure the application runs with least privilege. Monitor logs for suspicious access patterns or attempts to exploit the fileName parameter. If possible, consider disabling or restricting access to the vulnerable download.do endpoint until a patch is available. Organizations should also engage with Four-Faith for updates and consider alternative solutions if remediation is delayed. Regular backups and incident response plans should be reviewed to prepare for potential exploitation scenarios.
