CVE-2025-3707 is a SQL Injection vulnerability identified in the Sunnet eHRD CTMS (Clinical Trial Management System). This vulnerability arises due to improper neutralization of special elements used in SQL commands (CWE-89), allowing an attacker with regular user privileges to inject arbitrary SQL commands remotely. The vulnerability does not require user interaction and can be exploited over the network (AV:N), with low attack complexity (AC:L). The attacker must have some level of privileges (PR:L), but no elevated or administrative rights are necessary. Exploitation can lead to unauthorized reading of database contents, impacting the confidentiality of sensitive data stored within the CTMS. The vulnerability does not affect the integrity or availability of the system, as the injection is limited to reading data rather than modifying or deleting it. The CVSS v3.1 base score is 6.5, categorized as medium severity. No known exploits are currently reported in the wild, and no patches have been published yet. The affected version is indicated as '0', which likely means the initial or an unspecified version of the product. The vulnerability was reserved in mid-April 2025 and published in early May 2025. Given the nature of CTMS software, which manages clinical trial data, the exposed data could include sensitive patient information, trial protocols, and other regulated data, making confidentiality breaches particularly impactful.

For European organizations, especially those involved in clinical research, pharmaceutical development, and healthcare, this vulnerability poses a significant risk to the confidentiality of sensitive clinical trial data. Unauthorized disclosure of patient data or proprietary trial information could lead to regulatory non-compliance with GDPR and other data protection laws, resulting in legal penalties and reputational damage. Additionally, exposure of clinical trial data could undermine competitive advantages and intellectual property protections for pharmaceutical companies. While the vulnerability does not allow data modification or system disruption, the ability to read sensitive data remotely by a user with regular privileges expands the attack surface considerably. Organizations using Sunnet eHRD CTMS must consider the risk of insider threats or compromised user accounts being leveraged to exploit this vulnerability. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for targeted attacks, especially as the vulnerability becomes publicly known.

1. Immediate mitigation should focus on restricting access to the eHRD CTMS system to trusted networks and users, implementing strict network segmentation and access controls to limit exposure. 2. Enforce the principle of least privilege rigorously, ensuring users have only the minimum necessary permissions to perform their roles, thereby reducing the risk of exploitation by low-privilege accounts. 3. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the CTMS application. 4. Conduct thorough input validation and sanitization on all user-supplied data within the application, ideally through prepared statements or parameterized queries, although this requires vendor intervention. 5. Monitor database query logs and application logs for unusual or suspicious SQL queries indicative of injection attempts. 6. Engage with Sunnet to obtain patches or updates as soon as they become available; in the meantime, consider temporary compensating controls such as disabling vulnerable modules or features if feasible. 7. Perform regular security assessments and penetration testing focused on the CTMS environment to identify and remediate injection points proactively. 8. Educate users about the risks of credential compromise and enforce strong authentication mechanisms, including multi-factor authentication, to reduce the likelihood of account misuse.
