CVE-2025-6664 is a Cross-Site Request Forgery (CSRF) vulnerability identified in version 1.0 of the CodeAstro Patient Record Management System, a healthcare software product used for managing patient records. The vulnerability arises from an unspecified function within the system that fails to adequately verify the origin of requests, allowing an attacker to craft malicious web requests that, when executed by an authenticated user, can perform unauthorized actions on their behalf. The vulnerability is remotely exploitable without requiring any authentication or privileges, but it does require user interaction, such as the victim visiting a malicious website or clicking a crafted link. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the ease of exploitation (network accessible, low attack complexity) and the impact primarily on integrity (limited impact on data modification) and a low impact on availability and confidentiality. The vulnerability does not require user credentials or elevated privileges, but it does require the victim to interact with malicious content, which is typical for CSRF attacks. No patches or mitigations have been officially released at the time of publication, and while no known exploits have been observed in the wild, the exploit details have been publicly disclosed, increasing the risk of exploitation. Given the nature of the affected product—patient record management—the vulnerability could allow attackers to manipulate patient data or system settings, potentially leading to inaccurate medical records or unauthorized changes in patient management workflows.

For European healthcare organizations using CodeAstro Patient Record Management System 1.0, this vulnerability poses a significant risk to the integrity of patient data and the reliability of healthcare operations. Unauthorized actions triggered via CSRF could result in altered patient records, mismanagement of treatment plans, or unauthorized disclosure of sensitive health information if combined with other vulnerabilities. Although the confidentiality impact is rated low, the integrity impact is more concerning in a healthcare context where data accuracy is critical. Disruption or manipulation of patient records could lead to medical errors, regulatory non-compliance (e.g., GDPR violations), and reputational damage. The remote and unauthenticated nature of the attack vector means that attackers can target healthcare staff through phishing or malicious websites, increasing the attack surface. European healthcare providers are particularly sensitive to such threats due to strict data protection regulations and the critical nature of healthcare services. The lack of available patches means organizations must rely on compensating controls until a fix is released.

1. Implement strict CSRF protections at the application level, such as synchronizer tokens or double-submit cookies, to validate the origin of requests. 2. Employ web application firewalls (WAFs) with rules specifically designed to detect and block CSRF attack patterns targeting the Patient Record Management System. 3. Conduct user awareness training focused on phishing and social engineering to reduce the likelihood of users interacting with malicious content that could trigger CSRF attacks. 4. Restrict access to the Patient Record Management System to trusted networks or VPNs to reduce exposure to external threats. 5. Monitor application logs for unusual or unauthorized actions that could indicate exploitation attempts. 6. Segregate duties and enforce least privilege principles within the system to limit the impact of unauthorized actions. 7. Engage with the vendor (CodeAstro) for timely updates and patches, and prepare to apply them promptly once available. 8. Consider implementing Content Security Policy (CSP) headers to reduce the risk of malicious script execution that could facilitate CSRF attacks. 9. Use multi-factor authentication (MFA) where possible to add an additional layer of security, although it does not directly prevent CSRF, it can reduce overall risk.
