CVE-2025-8502 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Online Medicine Guide application. The vulnerability exists in an unspecified functionality within the /changepass.php file, specifically through manipulation of the 'ups' parameter. This parameter is vulnerable to SQL injection attacks, allowing an unauthenticated remote attacker to inject malicious SQL code into the backend database queries. The vulnerability does not require any user interaction or authentication, making it remotely exploitable over the network. The CVSS v4.0 base score is 6.9, indicating a medium severity level, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability has been publicly disclosed, but there are no known exploits currently observed in the wild. The lack of a patch or mitigation guidance from the vendor increases the risk for affected users. SQL injection vulnerabilities can allow attackers to read, modify, or delete sensitive data, escalate privileges, or execute administrative operations on the database, potentially compromising the entire application and its data confidentiality and integrity. Given the application is an Online Medicine Guide, the data involved may include sensitive medical or personal information, increasing the risk to patient privacy and regulatory compliance.

For European organizations, this vulnerability poses significant risks, especially for healthcare providers, medical information platforms, and related service providers using the affected Online Medicine Guide 1.0. Exploitation could lead to unauthorized access to sensitive medical data, violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The ability to alter or delete data could disrupt healthcare operations, impacting patient care and trust. Additionally, attackers could leverage the vulnerability to gain further access into internal networks, potentially leading to broader compromises. The remote, unauthenticated nature of the exploit increases the likelihood of automated scanning and exploitation attempts, raising the urgency for European entities to address this vulnerability promptly. The absence of known exploits in the wild currently provides a window for proactive mitigation before widespread attacks occur.

Organizations using code-projects Online Medicine Guide 1.0 should immediately conduct a thorough security assessment of their installations. Specific mitigations include: 1) Implement input validation and parameterized queries or prepared statements in the /changepass.php script to prevent SQL injection. 2) If source code modification is not feasible, deploy Web Application Firewalls (WAFs) with custom rules to detect and block malicious SQL injection payloads targeting the 'ups' parameter. 3) Monitor application logs and network traffic for unusual or suspicious activity related to /changepass.php requests. 4) Restrict database user privileges to the minimum necessary to limit the impact of potential injection. 5) Isolate the affected application server within the network to reduce lateral movement risk. 6) Engage with the vendor or community to obtain or develop patches and apply them as soon as available. 7) Educate IT and security teams about this vulnerability and ensure incident response plans are updated to address potential exploitation. 8) Regularly back up critical data to enable recovery in case of data tampering or loss.
