CVE-2025-8495 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Intern Membership Management System, specifically within the /admin/edit_admin_query.php file. The vulnerability arises from improper sanitization or validation of the 'Username' parameter, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. Exploiting this flaw could enable attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or even complete compromise of the membership management system's database. The CVSS 4.0 score is 6.9, indicating a medium severity level, reflecting that while the attack vector is network-based and requires no privileges or user interaction, the impact on confidentiality, integrity, and availability is limited to low or partial. The vulnerability is publicly disclosed, but no known exploits in the wild have been reported yet. The lack of available patches or vendor advisories increases the risk for organizations still running the affected version. Given the nature of membership management systems, which often store sensitive personal and organizational data, exploitation could lead to data breaches, unauthorized administrative access, and disruption of membership services.

For European organizations using the code-projects Intern Membership Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of member data. Exploitation could lead to unauthorized disclosure of personal information, violating GDPR and other data protection regulations, potentially resulting in legal penalties and reputational damage. The ability to remotely execute SQL injection without authentication increases the attack surface, making it easier for threat actors to compromise systems. Disruption of membership management services could impact organizational operations, member communications, and trust. Additionally, compromised systems could serve as pivot points for further attacks within the network. The medium CVSS score suggests that while the vulnerability is serious, the overall impact might be somewhat contained depending on the deployment context and existing security controls.

Organizations should immediately assess their exposure by identifying any deployments of code-projects Intern Membership Management System version 1.0. Since no official patches are currently available, mitigation should focus on implementing web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the 'Username' parameter in /admin/edit_admin_query.php. Input validation and parameterized queries should be enforced if source code access is possible to remediate the root cause. Restricting access to the administrative interface by IP whitelisting or VPN-only access can reduce exposure. Continuous monitoring of logs for suspicious SQL errors or unusual database queries is recommended to detect exploitation attempts early. Organizations should also prepare incident response plans specific to SQL injection attacks and consider upgrading or replacing the affected system with a more secure alternative as soon as feasible.
