CVE-2025-4458 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Patient Record Management System, specifically within the /edit_upatient.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which can be manipulated by an attacker to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 5.3, reflecting its moderate impact and ease of exploitation. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:L), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), indicating partial compromise potential. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of exploitation. Given that the affected system manages sensitive patient records, exploitation could lead to unauthorized data access, data manipulation, or disruption of healthcare services. The vulnerability does not involve complex chaining or advanced techniques, making it accessible to moderately skilled attackers. The absence of a patch link suggests that remediation may not yet be available, emphasizing the need for immediate mitigation efforts by users of this system.

For European organizations, particularly healthcare providers using the code-projects Patient Record Management System 1.0, this vulnerability poses significant risks. Patient record systems contain highly sensitive personal health information protected under GDPR, and any unauthorized access or data breach could lead to severe legal and financial consequences. Exploitation could result in exposure of confidential patient data, undermining patient privacy and trust. Additionally, attackers could alter or delete patient records, potentially impacting clinical decisions and patient safety. Disruption of the system could also affect healthcare delivery, causing operational downtime. The medium severity rating suggests that while the impact is not catastrophic, the risk remains substantial due to the critical nature of healthcare data and services. European healthcare entities are prime targets for cyberattacks, and the public availability of exploit code increases the likelihood of attempted intrusions. Furthermore, regulatory bodies in Europe may impose strict penalties for breaches involving patient data, amplifying the impact of successful exploitation.

Given the absence of an official patch, European organizations should implement immediate compensating controls. First, restrict external access to the Patient Record Management System by enforcing network segmentation and firewall rules to limit exposure of the /edit_upatient.php endpoint. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ID' parameter. Conduct thorough input validation and sanitization at the application level, ideally using parameterized queries or prepared statements to prevent injection. Monitor logs for suspicious activity related to SQL errors or unusual database queries. Implement strict access controls and audit trails to detect unauthorized access attempts. Organizations should also engage with the vendor to obtain or expedite a security patch and plan for prompt deployment once available. Regular security assessments and penetration testing focused on injection vulnerabilities are recommended to identify and remediate similar issues proactively. Finally, ensure that backups of patient data are maintained securely and tested for integrity to enable recovery in case of data manipulation or loss.
