CVE-2024-37802 identifies a critical SQL injection vulnerability in the Patient Info module of CodeProjects Health Care Hospital Management System version 1.0. The vulnerability arises from improper sanitization of the 'searvalu' parameter, which is used in SQL queries without adequate validation or parameterization. This allows an unauthenticated attacker to inject malicious SQL code remotely over the network, potentially retrieving, modifying, or deleting sensitive patient data stored in the backend database. The CVSS v3.1 score of 9.4 reflects the vulnerability's high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact includes high confidentiality and integrity loss, with a low impact on availability. Although no public exploits have been reported yet, the vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), a well-known and frequently exploited weakness. The lack of available patches increases the urgency for organizations to implement compensating controls. Given the criticality of healthcare data and regulatory requirements, exploitation could result in severe privacy breaches, regulatory penalties, and loss of trust.

The exploitation of this SQL injection vulnerability could have severe consequences for healthcare organizations worldwide. Attackers could gain unauthorized access to sensitive patient records, including personal identification and medical history, leading to privacy violations and potential identity theft. Data integrity could be compromised by unauthorized modification or deletion of records, disrupting patient care and hospital operations. Although availability impact is rated low, targeted attacks could still cause partial denial of service or data corruption. The breach of healthcare data can result in regulatory fines under laws such as HIPAA, GDPR, and others, as well as reputational damage. Given the critical nature of hospital management systems, successful exploitation could also facilitate further attacks within the network, such as lateral movement or ransomware deployment. The absence of known exploits currently provides a window for proactive defense, but the vulnerability’s ease of exploitation and high impact make it a significant threat.

Organizations using CodeProjects Health Care Hospital Management System v1.0 should immediately conduct a thorough security review of the Patient Info module, focusing on the 'searvalu' parameter. Since no official patches are currently available, implement the following mitigations: 1) Apply strict input validation and sanitization on all user-supplied inputs, especially the 'searvalu' parameter, to reject or escape SQL control characters. 2) Refactor database queries to use parameterized statements or prepared queries to prevent injection. 3) Employ web application firewalls (WAFs) with rules designed to detect and block SQL injection attempts targeting this parameter. 4) Restrict network access to the hospital management system to trusted internal networks or VPNs to reduce exposure. 5) Monitor logs for suspicious query patterns or repeated failed attempts indicative of exploitation attempts. 6) Plan and prioritize deployment of official patches or updates from the vendor once available. 7) Conduct employee training on security best practices and incident response readiness. These targeted actions will reduce the risk of exploitation until a permanent fix is released.
