CVE-2025-8498 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Medicine Guide application, specifically within the /cart/index.php file. The vulnerability arises from improper sanitization or validation of the 'uname' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially altering the intended database queries. This can lead to unauthorized data access, data modification, or even deletion, depending on the database permissions and the nature of the injected payload. The vulnerability requires no authentication or user interaction, making it exploitable by any remote attacker with network access to the affected application. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is rated as low individually but combined can lead to significant compromise of the affected system. No official patches or mitigations have been published yet, and while no known exploits are currently observed in the wild, public disclosure of the exploit code increases the risk of exploitation.

For European organizations using the Online Medicine Guide 1.0, this vulnerability poses a risk of unauthorized access to sensitive medical and user data stored in the backend database. Given the nature of the application (medicine guide with cart functionality), the database may contain personal health information (PHI), user credentials, and transaction records, which are highly sensitive under GDPR regulations. Exploitation could lead to data breaches, loss of data integrity, and disruption of service availability, potentially impacting patient care and trust. The exposure of PHI could result in significant regulatory penalties and reputational damage. Additionally, attackers could leverage the vulnerability to pivot within the network or escalate privileges if the database is connected to other critical systems. The medium severity rating suggests a moderate but tangible risk that requires timely remediation to prevent exploitation.

1. Immediate code review and remediation of the /cart/index.php file to implement proper input validation and parameterized queries (prepared statements) for the 'uname' parameter to prevent SQL injection. 2. Employ Web Application Firewalls (WAF) with rules specifically targeting SQL injection patterns to provide a temporary protective layer until patches are applied. 3. Conduct a comprehensive security audit of the entire Online Medicine Guide application to identify and remediate any other injection points or vulnerabilities. 4. Monitor application logs for suspicious activities related to the 'uname' parameter or unusual database query patterns. 5. Restrict database user permissions to the minimum necessary, ensuring the application user cannot perform destructive operations beyond its scope. 6. Plan and deploy an update or patch from the vendor as soon as it becomes available, and test it in a staging environment before production rollout. 7. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases.
