CVE-2025-6411 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Art Gallery Management System, specifically within the /admin/changepropic.php file. The vulnerability arises from improper sanitization or validation of the 'imageid' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring user interaction or authentication, allowing them to inject arbitrary SQL commands into the backend database queries. This can lead to unauthorized data access, data modification, or potentially full compromise of the database integrity and confidentiality. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been reported in the wild yet. The CVSS 4.0 score is 5.3, indicating a medium severity level, reflecting the ease of remote exploitation but limited privileges required (low privileges) and partial impact on confidentiality, integrity, and availability. The vulnerability does not affect the system’s scope broadly but targets a specific administrative functionality, which may limit the attack surface to administrative users or systems with access to this component. However, since no authentication is required, the attack vector is broader than typical admin-only vulnerabilities. The lack of available patches or mitigations from the vendor at this time increases the urgency for organizations to implement compensating controls.

For European organizations, the impact of this vulnerability can be significant, particularly for those using the PHPGurukul Art Gallery Management System version 1.1 in their operational environments. Exploitation could lead to unauthorized disclosure of sensitive data, including potentially customer or artwork information, alteration or deletion of records, and disruption of gallery management operations. This could result in reputational damage, regulatory non-compliance (especially under GDPR if personal data is involved), and financial losses. The remote and unauthenticated nature of the vulnerability increases the risk of automated attacks or exploitation by opportunistic threat actors. Organizations operating in the cultural, art, and heritage sectors, which often rely on specialized management systems, may face targeted attacks aiming to disrupt services or steal intellectual property. Additionally, the vulnerability could be leveraged as a foothold to pivot into broader network environments, increasing the risk of lateral movement and further compromise.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /admin/changepropic.php endpoint via network-level controls such as IP whitelisting or VPN-only access to limit exposure. 2) Deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'imageid' parameter. 3) Conducting thorough input validation and sanitization at the application layer if source code access and modification are possible, to neutralize injection payloads. 4) Monitoring logs for unusual or suspicious requests targeting the vulnerable endpoint to enable rapid detection and response. 5) Segmentation of the database and limiting database user privileges to minimize the impact of a successful injection. 6) Planning for an upgrade or migration to a patched or alternative system version as soon as it becomes available. 7) Educating administrative users about the risks and encouraging vigilance against suspicious activity. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable component and attack vector.
