CVE-2025-6410 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Art Gallery Management System, specifically within the /admin/edit-art-medium-detail.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This could lead to unauthorized data disclosure, data modification, or even deletion, depending on the database privileges. The vulnerability does not require user interaction or authentication, making it remotely exploitable with low attack complexity. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L) but with limited privileges (likely a low-level admin), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit has been publicly disclosed, although no known exploits in the wild have been reported yet. The lack of available patches increases the risk for organizations still running this vulnerable version. Given the critical nature of SQL injection vulnerabilities and the potential for data compromise, this vulnerability poses a significant risk to affected systems.

For European organizations using PHPGurukul Art Gallery Management System version 1.1, this vulnerability could lead to unauthorized access to sensitive data, including customer information, transaction records, or proprietary art catalog details. The integrity of the database could be compromised, allowing attackers to alter or delete records, which could disrupt business operations and damage reputation. Availability impacts are possible if attackers execute destructive queries. Given the art gallery management context, this could affect galleries, museums, or art dealers relying on this software for inventory and sales management. Data breaches could also lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. The remote exploitability without user interaction increases the attack surface, making it easier for threat actors to target these organizations. Although the CVSS score is medium, the critical classification and public exploit disclosure suggest that the real-world risk could be higher if exploited effectively.

1. Immediate upgrade or patching: Organizations should check for any available updates or patches from PHPGurukul addressing this vulnerability. If none are available, consider applying custom fixes to sanitize and validate the 'editid' parameter properly. 2. Web Application Firewall (WAF): Deploy a WAF with rules specifically designed to detect and block SQL injection attempts targeting the vulnerable parameter. 3. Database permissions: Restrict database user privileges used by the application to the minimum necessary, preventing destructive queries even if injection occurs. 4. Input validation: Implement strict server-side input validation and parameterized queries or prepared statements to prevent injection. 5. Monitoring and logging: Enable detailed logging of database queries and web requests to detect suspicious activities related to SQL injection attempts. 6. Network segmentation: Isolate the management system from public-facing networks where possible to reduce exposure. 7. Incident response readiness: Prepare to respond quickly to any signs of exploitation, including data breach protocols and forensic analysis. 8. Vendor engagement: Engage with PHPGurukul for official patches or guidance and monitor security advisories for updates.
