CVE-2025-45019 is a critical SQL injection vulnerability identified in the /add-foreigners-ticket.php file of the PHPGurukul Park Ticketing Management System version 2.0. This vulnerability arises due to improper sanitization and validation of the 'cprice' POST request parameter, which is directly used in SQL queries without adequate escaping or parameterization. An attacker can exploit this flaw remotely without any authentication or user interaction, by sending specially crafted HTTP POST requests to the vulnerable endpoint. Successful exploitation allows arbitrary code execution on the underlying server, which implies that the attacker can execute malicious SQL commands leading to unauthorized data access, modification, or deletion, and potentially escalate to full system compromise. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), and has a CVSS v3.1 base score of 9.8, indicating a critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. Although no known exploits are reported in the wild yet, the high severity and ease of exploitation make it a significant threat. The lack of vendor or product-specific details beyond the PHPGurukul Park Ticketing Management System v2.0 limits the scope of direct vendor mitigation guidance, but the vulnerability clearly stems from insecure coding practices in handling SQL queries within the application.

For European organizations, especially those operating in the tourism, leisure, and park management sectors, this vulnerability poses a severe risk. Exploitation could lead to unauthorized access to sensitive customer data, including personal identification and payment information, resulting in privacy breaches and regulatory non-compliance under GDPR. The ability to execute arbitrary code could allow attackers to implant malware, disrupt ticketing operations, or pivot within the network to compromise additional systems. This could cause significant operational downtime, financial losses, reputational damage, and potential legal liabilities. Given the criticality and remote exploitability, organizations using this ticketing system or similar vulnerable PHP-based web applications should consider this a high-priority threat. The impact extends beyond data confidentiality to integrity and availability, potentially affecting service continuity and customer trust.

1. Immediate application of patches or updates from the vendor once available is essential. In the absence of official patches, organizations should implement input validation and sanitization for the 'cprice' parameter, employing prepared statements or parameterized queries to prevent SQL injection. 2. Conduct a thorough code review of all PHP scripts handling user inputs to identify and remediate similar injection flaws. 3. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the /add-foreigners-ticket.php endpoint and the 'cprice' parameter. 4. Implement strict access controls and network segmentation to limit the exposure of the ticketing system to only trusted networks and users. 5. Enable detailed logging and monitoring of web application traffic to detect anomalous activities indicative of exploitation attempts. 6. Educate development teams on secure coding practices, emphasizing the use of parameterized queries and input validation. 7. Regularly perform security assessments and penetration testing focusing on injection vulnerabilities in web applications. These measures, combined, will significantly reduce the risk of exploitation and limit potential damage.
