CVE-2025-4013 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Art Gallery Management System, specifically within an unspecified function in the /admin/aboutus.php file. The vulnerability arises from improper sanitization or validation of the 'pagetitle' parameter, which is directly used in SQL queries. This flaw allows an unauthenticated remote attacker to inject arbitrary SQL code by manipulating the 'pagetitle' argument, potentially leading to unauthorized access, data leakage, data modification, or even complete compromise of the underlying database. The vulnerability does not require any user interaction or privileges, making it exploitable over the network without authentication. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, no privileges or user interaction required, but limited impact on confidentiality, integrity, and availability (each rated low). Although no known exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The absence of official patches or mitigation guidance from the vendor further elevates the urgency for affected organizations to implement protective measures. Given the nature of the vulnerability, attackers could leverage it to extract sensitive data from the database, alter or delete records, or escalate attacks within the affected environment, potentially impacting the confidentiality and integrity of stored information related to art gallery management operations.

For European organizations using the PHPGurukul Art Gallery Management System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Art galleries and cultural institutions often manage sensitive information such as artist details, artwork provenance, transaction records, and customer data. Exploitation could lead to unauthorized disclosure of proprietary or personal data, manipulation of records affecting business operations, or disruption of services. Given the remote and unauthenticated nature of the attack, threat actors could exploit this vulnerability to gain footholds within organizational networks, potentially leading to broader compromise. The impact is particularly critical for institutions that rely heavily on this system for operational continuity and data integrity. Moreover, the lack of patches means that organizations must rely on compensating controls to mitigate risk. The reputational damage and potential regulatory consequences under GDPR for data breaches further amplify the impact for European entities.

1. Immediate mitigation should include implementing a Web Application Firewall (WAF) with custom rules to detect and block SQL injection attempts targeting the 'pagetitle' parameter in /admin/aboutus.php. 2. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to sanitize all user inputs, especially the 'pagetitle' parameter. 3. If source code modification is not feasible immediately, restrict access to the /admin/ directory via IP whitelisting or VPN-only access to limit exposure. 4. Monitor database logs and web server logs for suspicious queries or unusual activity related to the vulnerable endpoint. 5. Engage with the vendor or community to obtain or develop patches or updated versions that address this vulnerability. 6. Perform regular security assessments and penetration testing focused on injection flaws to identify and remediate similar issues proactively. 7. Educate administrative users about the risks and signs of exploitation to enhance early detection and response capabilities.
