CVE-2025-8442 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Online Medicine Guide application. The vulnerability resides in the /cussignup.php file, specifically in the handling of the 'uname' parameter. An attacker can manipulate this parameter to inject malicious SQL code, which the backend database executes. This flaw allows remote attackers to execute arbitrary SQL commands without authentication or user interaction, potentially leading to unauthorized data access, data modification, or even full compromise of the database. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The vector details show that the attack can be performed remotely (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and no authentication (AT:N). The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), suggesting partial but not complete compromise of these security properties. No patches or exploit code are currently publicly available, and there are no known exploits in the wild. The vulnerability affects only version 1.0 of the product, which is an online medicine guide platform, likely used by healthcare providers or patients for medical information or services. The lack of authentication requirement and remote exploitability make this a significant risk, especially given the sensitive nature of healthcare data that may be stored or processed by the application. However, the medium severity rating reflects that the impact is not catastrophic or widespread but still requires prompt remediation.

For European organizations, particularly those in the healthcare sector using the Online Medicine Guide 1.0, this vulnerability poses a risk of unauthorized access to sensitive patient or medical data. Exploitation could lead to data breaches, undermining patient confidentiality and potentially violating GDPR regulations, which mandate strict protection of personal health information. The integrity of medical records could be compromised, leading to incorrect treatment decisions or loss of trust in healthcare providers. Availability impacts, while rated low, could still disrupt access to the medicine guide, affecting clinical workflows. The remote and unauthenticated nature of the attack increases the risk of exploitation, especially if the application is exposed to the internet without adequate network protections. European healthcare organizations are prime targets for cyberattacks due to the value of health data and the critical nature of healthcare services, making timely mitigation essential to avoid regulatory penalties and reputational damage.

Organizations should immediately assess their use of code-projects Online Medicine Guide version 1.0 and plan for an upgrade or patch once available. In the absence of an official patch, implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'uname' parameter in /cussignup.php. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters used in SQL queries. Employ parameterized queries or prepared statements in the application code to prevent injection. Restrict external access to the vulnerable endpoint by network segmentation or IP whitelisting where feasible. Monitor logs for unusual database queries or failed login attempts that may indicate exploitation attempts. Additionally, perform regular security assessments and penetration testing focused on injection vulnerabilities. Ensure that backups of critical data are maintained and tested for integrity to enable recovery in case of compromise. Finally, educate development teams on secure coding practices to prevent similar vulnerabilities in future releases.
