CVE-2025-11336 is a path traversal vulnerability identified in the Four-Faith Water Conservancy Informatization Platform versions 2.0, 2.1, and 2.2. The vulnerability exists due to insufficient validation of the 'fileName' parameter in specific URLs such as /stAlarmConfigure/index.do/../../aloneReport/download.do and otherlogout.do. By manipulating this parameter, an attacker can traverse directories on the server and access arbitrary files outside the intended directory scope. This can lead to unauthorized disclosure of sensitive files, including configuration files, logs, or other critical data stored on the server. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing the attack surface. The CVSS v4.0 score of 6.9 reflects a medium severity level, primarily due to the lack of impact on integrity or availability but significant confidentiality concerns. The vendor has been contacted but has not responded or released patches, and public exploit information is available, which raises the risk of exploitation. The affected platform is used in water conservancy informatization, a critical infrastructure sector, making this vulnerability particularly concerning for organizations managing water resources. The lack of vendor response necessitates that organizations implement their own mitigations to protect against potential attacks.

The primary impact of CVE-2025-11336 is unauthorized disclosure of sensitive information due to arbitrary file access on affected servers. For European organizations involved in water resource management, this could mean exposure of critical infrastructure data, operational details, or credentials, which could be leveraged for further attacks or sabotage. Compromise of such information could disrupt water management services, leading to operational inefficiencies or safety risks. Additionally, attackers could use the access to gather intelligence for more advanced attacks targeting availability or integrity of water systems. The vulnerability’s remote and unauthenticated nature increases the likelihood of exploitation, especially given the public availability of exploit details. This poses a significant risk to national and regional water management authorities, private companies, and any entities relying on the Four-Faith platform. Data privacy regulations in Europe, such as GDPR, may also be implicated if personal or sensitive data is exposed, leading to legal and financial consequences.

1. Immediately restrict external access to the affected endpoints (/stAlarmConfigure/index.do, /aloneReport/download.do, otherlogout.do) via network controls such as firewalls or web application firewalls (WAFs). 2. Implement strict input validation and sanitization on the 'fileName' parameter to prevent directory traversal characters (e.g., '../'). 3. Employ least privilege principles on the file system to limit the files accessible by the application process, ensuring sensitive files are not readable by the web server. 4. Monitor server logs and network traffic for unusual access patterns or attempts to exploit path traversal. 5. If possible, isolate the affected platform in a segmented network zone to reduce exposure. 6. Engage with Four-Faith or third-party security experts to develop or apply patches or workarounds. 7. Conduct regular security assessments and penetration tests focusing on web application vulnerabilities. 8. Prepare incident response plans specific to water infrastructure to quickly address potential breaches. 9. Educate operational staff about the risks and signs of exploitation attempts. 10. Consider deploying runtime application self-protection (RASP) tools to detect and block exploitation attempts in real time.
