CVE-2025-4014 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Art Gallery Management System, specifically within the /admin/manage-art-medium.php file. The vulnerability arises from improper sanitization or validation of the 'artmed' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring any authentication or user interaction, by crafting specially designed input to the vulnerable parameter. This allows the attacker to inject arbitrary SQL commands into the backend database queries. The consequences of successful exploitation include unauthorized data access, data modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the system's data. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known active exploits have been reported in the wild to date. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with attack vector network (remote), low attack complexity, no privileges or user interaction required, and low impact on confidentiality, integrity, and availability individually but combined leading to a medium overall impact. The vulnerability affects only version 1.0 of the product, and no official patches or mitigations have been published yet.

For European organizations using PHPGurukul Art Gallery Management System 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive data such as artwork details, customer information, and transaction records. This could result in data breaches, loss of customer trust, and potential regulatory penalties under GDPR due to exposure of personal data. Additionally, attackers could alter or delete critical data, disrupting business operations and causing reputational damage. Since the vulnerability is remotely exploitable without authentication, attackers can launch attacks from anywhere, increasing the threat surface. Art galleries and cultural institutions in Europe that rely on this system for managing their collections and sales are particularly at risk. The public disclosure of the vulnerability further elevates the risk as threat actors may develop and deploy automated exploit tools. Although no active exploits are known, the ease of exploitation and potential impact on data security and operational continuity make this a concern for affected entities.

1. Immediate mitigation should include restricting access to the /admin/manage-art-medium.php endpoint by implementing IP whitelisting or VPN access to limit exposure to trusted users only. 2. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'artmed' parameter. 3. Conduct a thorough code review and implement proper input validation and parameterized queries or prepared statements to eliminate SQL injection vulnerabilities. 4. If possible, upgrade to a patched or newer version of the PHPGurukul Art Gallery Management System once available. 5. Monitor logs for suspicious activities related to the vulnerable parameter and set up alerts for unusual database query patterns. 6. Educate administrative users about the risk and encourage strong authentication methods to reduce the risk of lateral attacks. 7. As a temporary workaround, disable or limit the functionality that processes the 'artmed' parameter if it is not critical to operations. 8. Engage with the vendor or community to obtain or develop patches and share threat intelligence regarding this vulnerability.
