CVE-2025-9028 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Medicine Guide application. The vulnerability arises from improper sanitization of the 'phuname' parameter in the /adphar.php endpoint, allowing an attacker to inject malicious SQL code. This flaw enables remote attackers to manipulate backend database queries without requiring authentication or user interaction. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The vector metrics specify that the attack can be performed remotely (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), suggesting partial data disclosure or modification but not full system compromise. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The absence of patches or vendor advisories at this time means affected organizations must rely on mitigation strategies until an official fix is released. The vulnerability specifically targets the Online Medicine Guide product, which is likely used by healthcare providers or related organizations to manage medical information, making the confidentiality and integrity of patient data a critical concern.

For European organizations, particularly those in the healthcare sector using the Online Medicine Guide 1.0, this vulnerability poses a significant risk to patient data confidentiality and integrity. Exploitation could lead to unauthorized access to sensitive medical records, manipulation of medical information, or disruption of service availability. Such breaches could violate GDPR requirements, leading to legal penalties and reputational damage. The healthcare sector is a high-value target for cybercriminals due to the sensitivity of data and potential for ransom attacks. Even though the CVSS score indicates medium severity, the critical nature of healthcare data elevates the impact. Additionally, the ability to exploit this vulnerability remotely without authentication increases the attack surface. European healthcare providers relying on this software must consider the risk of data breaches, potential operational disruptions, and compliance violations.

Given the lack of an official patch, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /adphar.php endpoint through network-level controls such as firewalls or web application firewalls (WAFs) configured to detect and block SQL injection patterns targeting the 'phuname' parameter. 2) Employing input validation and sanitization at the application or proxy level to neutralize malicious SQL inputs. 3) Conducting thorough code reviews and applying manual or automated fixes to sanitize the 'phuname' parameter if source code access is available. 4) Monitoring logs for unusual query patterns or repeated access attempts to /adphar.php indicative of exploitation attempts. 5) Segregating the database with least privilege principles to limit the impact of any successful injection. 6) Preparing incident response plans specific to data breaches involving medical information. Organizations should also engage with the vendor for updates and patches and plan timely application of fixes once available.
