CVE-2025-11315 identifies a SQL injection vulnerability in version 1.0 of the Tipray Data Leakage Prevention System (天锐数据泄露防护系统), specifically within the findUserPage function of the findUserPage.do endpoint. The vulnerability arises from improper sanitization of the 'sort' parameter, which is directly used in SQL queries, enabling an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw allows attackers to manipulate backend database queries, potentially extracting sensitive data, altering records, or causing denial of service by corrupting database integrity. The vendor was notified early but has not issued any response or patch, and public exploit code is available, increasing the risk of exploitation. The CVSS 4.0 base score is 6.9 (medium), reflecting network attack vector, low complexity, no privileges or user interaction needed, and partial impact on confidentiality, integrity, and availability. The vulnerability affects only version 1.0 of the product, which is a data leakage prevention system primarily used to monitor and control sensitive data flow within organizations. The lack of vendor response and patch availability means affected organizations must rely on compensating controls until a fix is released.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive corporate or personal data, undermining data protection efforts and compliance with regulations such as GDPR. The integrity of data could be compromised, potentially disrupting business operations or causing erroneous data processing. Availability impacts could arise if attackers corrupt or delete critical database records, leading to service outages. Since the product is a Data Leakage Prevention system, its compromise ironically increases the risk of data exfiltration rather than preventing it. Organizations in sectors handling sensitive information—such as finance, healthcare, and government—are particularly at risk. The public availability of exploit code and absence of vendor patches heighten the urgency of addressing this vulnerability to prevent potential data breaches and reputational damage.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include: 1) Restricting network access to the affected system by placing it behind firewalls and limiting access to trusted IP addresses only; 2) Employing web application firewalls (WAFs) configured to detect and block SQL injection attempts, especially targeting the 'sort' parameter in HTTP requests; 3) Conducting thorough input validation and sanitization on all user-supplied parameters at the application or proxy level; 4) Monitoring database query logs and application logs for anomalous or suspicious activity indicative of injection attempts; 5) Isolating the affected system from critical internal networks to minimize lateral movement; 6) Preparing incident response plans specific to data leakage prevention systems; and 7) Engaging with the vendor or community for updates or unofficial patches. Organizations should also consider alternative DLP solutions if remediation is delayed.
