CVE-2025-6414 is a SQL Injection vulnerability identified in version 1.1 of the PHPGurukul Art Gallery Management System, specifically within the /admin/changeimage2.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 by injecting crafted SQL commands through the 'editid' argument, potentially allowing unauthorized access to the backend database. This could lead to unauthorized data retrieval, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The vulnerability does not require user interaction and can be exploited without authentication, increasing its risk profile. Although the CVSS v4.0 score is rated at 5.3 (medium severity), the presence of remote exploitability and lack of authentication requirements indicate a significant risk, especially if the system contains sensitive or critical data. No public patches or mitigations have been disclosed yet, and no known exploits are currently observed in the wild. The vulnerability's impact is limited to version 1.1 of the PHPGurukul Art Gallery Management System, which is a niche product primarily used by art galleries for managing digital assets and administrative tasks.

For European organizations using the PHPGurukul Art Gallery Management System version 1.1, this vulnerability poses a risk of unauthorized database access, which could lead to data breaches involving sensitive information such as artwork details, client data, and administrative records. The SQL Injection could allow attackers to extract confidential data, alter records, or disrupt gallery operations by corrupting or deleting data. This could result in reputational damage, financial loss, and regulatory non-compliance, particularly under GDPR requirements for data protection. Given the specialized nature of the product, the impact is likely concentrated on small to medium-sized art galleries or cultural institutions using this system. The remote and unauthenticated nature of the exploit increases the threat level, as attackers can target vulnerable installations over the internet without needing credentials or user interaction. However, the medium CVSS score suggests that while the vulnerability is serious, it may require some conditions or limitations in the attack vector or impact scope, such as partial database access or limited privilege escalation.

1. Immediate mitigation should involve restricting access to the /admin/changeimage2.php endpoint via network controls such as IP whitelisting or VPN access to limit exposure to trusted users only. 2. Implement Web Application Firewall (WAF) rules specifically targeting SQL Injection patterns on the 'editid' parameter to block malicious payloads. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize the 'editid' input, eliminating direct concatenation into SQL commands. 4. If possible, upgrade to a patched or newer version of the PHPGurukul Art Gallery Management System once available, or consider alternative software with active security support. 5. Monitor database logs and application logs for unusual queries or access patterns indicative of exploitation attempts. 6. Educate administrative users about the risks and encourage minimal use of the vulnerable functionality until a fix is applied. 7. Regularly back up database contents to enable recovery in case of data tampering or loss due to exploitation.
