CVE-2025-11309 identifies a SQL injection vulnerability in the Tipray 厦门天锐科技股份有限公司 Data Leakage Prevention System (DLP) version 1.0. The vulnerability is located in the doFilter function within the findDeptPage.do endpoint, specifically through manipulation of the 'sort' parameter. This parameter is not properly sanitized, allowing an attacker to inject malicious SQL queries remotely without requiring authentication or user interaction. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with network attack vector, low complexity, and no privileges or user interaction needed. Exploitation can lead to unauthorized access to sensitive data, data modification, or deletion, compromising confidentiality, integrity, and availability. The vendor was notified but has not issued any patches or advisories, and public exploit code has been released, increasing the risk of exploitation. The lack of authentication and remote exploitability make this vulnerability particularly dangerous for exposed systems. The DLP system is designed to prevent data leakage, so a compromise could undermine the very protections it is meant to enforce, potentially leading to significant data breaches.

For European organizations, the impact of this vulnerability can be substantial, especially for those in regulated industries such as finance, healthcare, and government, where data leakage prevention systems are critical. Exploitation could result in unauthorized disclosure of sensitive or personal data, violating GDPR and other data protection regulations, leading to legal and financial penalties. Integrity of data could be compromised, affecting business operations and trustworthiness of information. Availability of the DLP system might be disrupted, reducing the organization's ability to monitor and prevent data leakage. Since the vulnerability requires no authentication and can be exploited remotely, attackers could leverage it to gain footholds within networks or exfiltrate data stealthily. The public availability of exploit code increases the likelihood of opportunistic attacks. Organizations relying on Tipray’s DLP system must consider the risk of targeted attacks and potential reputational damage from data breaches.

Given the absence of vendor patches, European organizations should implement immediate compensating controls. First, restrict network access to the affected DLP system, limiting exposure to trusted internal networks or VPNs only. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'sort' parameter in findDeptPage.do. Conduct thorough input validation and sanitization at the application or proxy level if possible. Monitor logs for unusual query patterns or errors indicative of SQL injection attempts. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts. If feasible, isolate the vulnerable system and plan for replacement or upgrade once a patch is available. Regularly review and update incident response plans to address potential data breaches stemming from this vulnerability. Engage with the vendor for updates and consider alternative DLP solutions with better security track records if no remediation is forthcoming.
