CVE-2025-6412 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Art Gallery Management System, specifically within the /admin/changeimage.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is susceptible to malicious SQL payloads. An attacker can remotely exploit this flaw without requiring user interaction or prior authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability allows an attacker to manipulate backend SQL queries, potentially leading to unauthorized data access, modification, or deletion within the underlying database. Although the CVSS score is rated medium (5.3), the exploitability is relatively straightforward due to low attack complexity and no user interaction needed. The vulnerability affects a niche web application used for managing art gallery operations, which may include sensitive data such as artwork inventories, artist details, and transaction records. No patches or fixes have been publicly disclosed yet, and no known exploits are currently observed in the wild. However, the public disclosure of the vulnerability increases the risk of exploitation attempts by threat actors. The vulnerability does not require authentication but does require low privileges, which suggests that the attacker might need some level of access, possibly a low-privileged admin or staff account, to exploit the flaw. The scope of impact is limited to installations running the affected version of the PHPGurukul Art Gallery Management System, which is a specialized product with limited market penetration.

For European organizations, the impact of this vulnerability depends largely on the adoption of the PHPGurukul Art Gallery Management System within cultural institutions, galleries, or art-related businesses. Successful exploitation could lead to unauthorized access to sensitive data such as artwork provenance, pricing, artist information, and transactional records, potentially causing financial loss, reputational damage, and regulatory compliance issues (e.g., GDPR violations due to exposure of personal data). The integrity of gallery records could be compromised, leading to fraudulent alterations or deletion of critical data. Availability impact is limited but possible if attackers leverage the injection to disrupt database operations. Given the medium severity and the requirement for low privileges, the threat is moderate but should not be underestimated, especially for organizations managing valuable or sensitive art collections. The lack of known exploits in the wild currently reduces immediate risk, but public disclosure increases the likelihood of targeted attacks, especially from financially motivated or opportunistic attackers.

1. Immediate mitigation should include restricting access to the /admin/changeimage.php functionality to trusted personnel only, ideally via network segmentation or VPN access. 2. Implement strict input validation and parameterized queries (prepared statements) for the 'editid' parameter to prevent SQL injection. 3. Conduct a thorough code review of all input handling in the affected application to identify and remediate similar injection points. 4. Monitor web server and database logs for suspicious activity related to the 'editid' parameter or unusual query patterns. 5. If possible, deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. 6. Engage with the vendor or community to obtain or develop patches and update to a fixed version once available. 7. Educate administrative users on the risks and encourage the use of strong, unique credentials to reduce the risk of privilege escalation. 8. Regularly back up the database and application data to enable recovery in case of data tampering or loss. 9. Consider isolating the application environment and applying the principle of least privilege to database accounts used by the application to limit the potential damage of an injection attack.
