CVE-2025-39357 is a high-severity SQL Injection vulnerability (CWE-89) found in the mojoomla Hospital Management System. This vulnerability arises due to improper neutralization of special elements used in SQL commands, allowing an attacker to inject malicious SQL code. The affected versions include all versions up to 47.0 (dated 20-11-2023). The vulnerability has a CVSS 3.1 score of 8.5, indicating a high impact with network attack vector, low attack complexity, requiring privileges but no user interaction, and with a scope change. Specifically, the vulnerability allows an attacker with some level of privileges (PR:L) to execute unauthorized SQL commands remotely (AV:N), potentially leading to a compromise of confidentiality (C:H), with no impact on integrity (I:N) and limited impact on availability (A:L). The scope change (S:C) indicates that the vulnerability affects resources beyond the initially vulnerable component. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the sensitive nature of the data managed by hospital systems, including patient records and operational data. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability could be exploited to extract sensitive patient data, potentially violating data protection regulations, or to cause partial denial of service by leveraging the limited availability impact. Given the critical role of hospital management systems in healthcare delivery, exploitation could disrupt healthcare services and compromise patient privacy.

For European organizations, particularly healthcare providers using mojoomla Hospital Management System, this vulnerability presents a serious risk to patient data confidentiality and operational continuity. Exploitation could lead to unauthorized disclosure of sensitive health information, violating GDPR and other data protection laws, resulting in legal penalties and reputational damage. The partial availability impact could disrupt hospital operations, affecting patient care and emergency response. Additionally, the scope change suggests that exploitation might affect other interconnected systems or databases, amplifying the impact. Given the critical infrastructure nature of healthcare, successful attacks could also erode public trust and cause cascading effects on healthcare delivery. The requirement for privileges to exploit the vulnerability means insider threats or compromised credentials could be leveraged by attackers, emphasizing the need for strict access controls and monitoring.

1. Immediate implementation of strict input validation and parameterized queries or prepared statements in all database interactions within the mojoomla Hospital Management System to prevent SQL injection. 2. Restrict database user privileges to the minimum necessary, ensuring that the application accounts do not have excessive permissions that could be exploited. 3. Conduct thorough code reviews and security testing focused on SQL injection vectors, especially in modules handling user input or external data. 4. Monitor logs for unusual database queries or access patterns that could indicate attempted exploitation. 5. Implement network segmentation to isolate the hospital management system from other critical infrastructure, limiting the scope of potential attacks. 6. Enforce multi-factor authentication and robust credential management to reduce the risk of privilege escalation. 7. Prepare incident response plans specific to healthcare data breaches, including notification procedures compliant with GDPR. 8. Engage with mojoomla or security vendors for timely patches or updates once available, and apply them promptly. 9. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block SQL injection attempts as an interim protective measure.
