CVE-2025-4703 is a SQL Injection vulnerability identified in version 1.13 of the PHPGurukul Vehicle Parking Management System, specifically within the /admin/admin-profile.php file. The vulnerability arises due to improper sanitization or validation of the 'contactnumber' parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands against the backend database without requiring any user interaction or privileges. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 6.9, reflecting its network attack vector, low attack complexity, and no need for authentication or user interaction. Exploiting this vulnerability could lead to unauthorized data access, data modification, or potentially database corruption depending on the database permissions and schema. Although no known exploits are currently observed in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The absence of available patches or mitigations from the vendor at the time of publication further heightens the urgency for affected organizations to implement protective measures. Given the critical role of vehicle parking management systems in operational logistics, unauthorized access or data breaches could disrupt services and compromise sensitive user or operational data.

For European organizations utilizing PHPGurukul Vehicle Parking Management System version 1.13, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive information such as user contact details, vehicle registration data, and administrative credentials. This breach of confidentiality could violate GDPR regulations, leading to legal and financial penalties. Additionally, attackers could alter or delete parking management data, impacting the integrity and availability of services, potentially causing operational disruptions in facilities relying on automated parking systems. The remote and unauthenticated nature of the attack vector increases the likelihood of exploitation, especially in organizations with externally accessible administrative interfaces. The impact is particularly concerning for entities managing large-scale parking infrastructures such as airports, hospitals, or municipal parking authorities, where service disruption could have cascading effects on public safety and mobility. Furthermore, compromised systems could be leveraged as pivot points for broader network intrusions, increasing the overall cybersecurity risk posture of affected organizations.

Given the lack of an official patch at the time of disclosure, European organizations should adopt immediate compensating controls. First, restrict access to the /admin/admin-profile.php endpoint by implementing network-level controls such as IP whitelisting or VPN-only access to administrative interfaces. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'contactnumber' parameter. Conduct thorough input validation and sanitization on all user-supplied data, ideally using parameterized queries or prepared statements to prevent injection. Regularly audit and monitor database logs for anomalous queries indicative of exploitation attempts. Organizations should also consider isolating the parking management system within segmented network zones to limit lateral movement in case of compromise. Finally, maintain up-to-date backups of critical data to enable recovery from potential data corruption or deletion. Engage with the vendor for timely patch releases and apply updates promptly once available.
