CVE-2025-4309 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Art Gallery Management System, specifically within the /admin/add-art-type.php file. The vulnerability arises due to improper sanitization or validation of the 'arttype' parameter, which is directly used in SQL queries. An attacker can manipulate this parameter remotely without requiring authentication or user interaction, allowing them to inject malicious SQL code. This can lead to unauthorized access to the underlying database, potentially exposing sensitive data, modifying or deleting records, or even executing administrative commands depending on the database privileges. The CVSS 4.0 score of 6.9 classifies this as a medium severity issue, reflecting the ease of exploitation (network accessible, no privileges or user interaction needed) but limited impact on confidentiality, integrity, and availability (each rated low). No known exploits are currently active in the wild, but the vulnerability has been publicly disclosed, increasing the risk of exploitation. The lack of available patches or mitigations from the vendor at this time further elevates the risk for users of this specific software version.

For European organizations using PHPGurukul Art Gallery Management System 1.1, this vulnerability poses a tangible risk to the confidentiality and integrity of their art gallery management data. Exploitation could result in unauthorized disclosure of sensitive information such as artwork details, artist information, or internal administrative data. Additionally, attackers could alter or delete records, disrupting business operations and potentially causing reputational damage. Since the vulnerability is remotely exploitable without authentication, attackers could target exposed management interfaces over the internet. Although the overall severity is medium, organizations in Europe that rely on this system for managing valuable cultural assets or customer data could face operational disruptions and compliance risks, especially under GDPR regulations concerning data breaches. The absence of known active exploits currently provides a window for mitigation, but the public disclosure increases the likelihood of future attacks.

European organizations should immediately audit their use of PHPGurukul Art Gallery Management System, specifically verifying if version 1.1 is deployed. If so, they should restrict access to the /admin/add-art-type.php endpoint by implementing network-level controls such as IP whitelisting or VPN-only access to administrative interfaces. Input validation and sanitization should be applied to the 'arttype' parameter to prevent SQL injection, ideally by updating or patching the software if a vendor fix becomes available. In the absence of an official patch, organizations can implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this parameter. Regular database backups and monitoring for anomalous database queries or changes should be instituted to enable rapid detection and recovery. Finally, organizations should consider migrating to updated or alternative management systems with secure coding practices to reduce long-term risk.
