CVE-2025-6413 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Art Gallery Management System, specifically within the /admin/changeimage1.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is susceptible to malicious input manipulation. 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 injection allows the attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access, data modification, or even deletion. Although the CVSS score is rated medium (5.3), the vulnerability's critical classification in the description suggests that the impact could be significant depending on the deployment context. The vulnerability affects only version 1.1 of the product, and no official patches or fixes have been disclosed yet. No known exploits are currently observed in the wild, but public disclosure increases the risk of exploitation attempts. The vulnerability does not require user interaction but does require low privileges (PR:L), implying that an attacker might need some level of access, possibly a low-privileged authenticated session, to exploit the flaw. The lack of scope change (S:N) means the impact is confined to the vulnerable component or system. The vulnerability could compromise confidentiality, integrity, and availability of the affected system's data, especially sensitive information managed by the Art Gallery Management System, such as artwork details, user data, and administrative controls.

For European organizations using PHPGurukul Art Gallery Management System 1.1, this vulnerability poses a risk of unauthorized data disclosure, data tampering, and potential disruption of gallery management operations. Art galleries, museums, and cultural institutions relying on this system could suffer reputational damage, financial loss, and regulatory penalties under GDPR if personal or sensitive data is exposed. The ability to execute SQL injection remotely without user interaction increases the attack surface, especially if the system is accessible over the internet or internal networks with weak access controls. The medium CVSS score suggests moderate ease of exploitation but with potentially significant consequences. Since the vulnerability requires low privileges, insider threats or compromised low-level accounts could escalate the impact. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially after public disclosure. Disruption of availability or integrity could affect ticketing, inventory, or exhibition management, impacting business continuity. Additionally, attackers could leverage this vulnerability as a foothold for further lateral movement within the network.

1. Immediate mitigation should include restricting access to the /admin/changeimage1.php endpoint to trusted IP addresses or VPN-only access to reduce exposure. 2. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'editid' parameter. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements for all database interactions involving user-supplied input, especially the 'editid' parameter. 4. If possible, upgrade to a newer, patched version of the PHPGurukul Art Gallery Management System once available or apply vendor-supplied patches. 5. Monitor logs for suspicious activities related to SQL errors or unusual database queries originating from the admin interface. 6. Enforce the principle of least privilege for user accounts, ensuring that low-privileged users cannot access administrative functions unnecessarily. 7. Consider isolating the affected system within a segmented network zone to limit potential lateral movement. 8. Regularly back up critical data and verify the integrity of backups to enable recovery in case of data corruption or deletion. 9. Educate administrative users about the risks and signs of exploitation attempts to enhance detection capabilities.
