CVE-2025-8497 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Online Medicine Guide application. The vulnerability exists in the /cusfindphar2.php file, specifically in the handling of the 'Search' parameter. Due to insufficient input validation or sanitization, an attacker can manipulate this parameter to inject malicious SQL code. This injection allows unauthorized access to the backend database, potentially enabling attackers to read, modify, or delete sensitive data stored within the application. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing the risk of automated or widespread attacks. Although the CVSS 4.0 score is 6.9 (medium severity), the lack of authentication and remote exploitability make this a significant threat. The vulnerability affects only version 1.0 of the Online Medicine Guide, and no official patches have been published yet. While no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the likelihood of exploitation attempts. The vulnerability impacts confidentiality, integrity, and availability of the application’s data, as attackers could extract sensitive medical information, alter records, or disrupt service operations.

For European organizations, especially healthcare providers, pharmacies, and medical information services using the Online Medicine Guide 1.0, this vulnerability poses a serious risk. Exploitation could lead to unauthorized disclosure of sensitive patient or pharmaceutical data, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. Integrity of medical data could be compromised, affecting clinical decisions and patient safety. Availability could also be impacted if attackers execute destructive SQL commands or cause database corruption. The healthcare sector in Europe is a high-value target for cybercriminals and nation-state actors, increasing the threat level. Additionally, the remote and unauthenticated nature of the exploit means attackers can launch attacks at scale, potentially affecting multiple organizations simultaneously. This could disrupt healthcare services and erode trust in digital health platforms.

1. Immediate mitigation should include disabling or restricting access to the vulnerable /cusfindphar2.php endpoint until a patch is available. 2. Implement strict input validation and parameterized queries or prepared statements in the code to prevent SQL injection. 3. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'Search' parameter. 4. Conduct thorough code reviews and security testing of the Online Medicine Guide application, focusing on all user input handling. 5. Monitor application logs for unusual query patterns or errors indicative of injection attempts. 6. If possible, upgrade to a newer, patched version of the software once released by the vendor. 7. Educate IT and security teams about this vulnerability and ensure incident response plans include SQL injection attack scenarios. 8. For organizations unable to patch immediately, consider network segmentation and access controls to limit exposure of the affected application to trusted users only.
