CVE-2025-45017 is a critical SQL injection vulnerability identified in the edit-ticket.php script of the PHPGurukul Park Ticketing Management System version 2.0. This vulnerability arises from improper sanitization of the 'tprice' POST parameter, which allows remote attackers to inject malicious SQL code. Exploiting this flaw, an attacker can execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), indicating a classic SQL injection scenario. Given the CVSS 3.1 base score of 9.8, the vulnerability is highly severe, with an attack vector that is network-based (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact encompasses full confidentiality, integrity, and availability compromise (C:H/I:H/A:H), meaning attackers can exfiltrate sensitive data, modify or delete records, and potentially execute arbitrary code on the server through database manipulation. Although no known exploits are currently reported in the wild, the critical nature and ease of exploitation make it a significant threat. The lack of vendor or product-specific information limits precise identification, but the vulnerability specifically targets the PHPGurukul Park Ticketing Management System, a web-based application used for managing park ticketing operations. The absence of patch links suggests that no official fix has been released yet, increasing the urgency for mitigation.

For European organizations, especially those involved in tourism, leisure, and park management sectors using the PHPGurukul Park Ticketing Management System, this vulnerability poses a severe risk. Exploitation could lead to unauthorized access to customer data, including personal and payment information, resulting in data breaches and regulatory non-compliance under GDPR. The ability to execute arbitrary code could allow attackers to pivot within the network, potentially compromising other critical systems. Service disruption due to data manipulation or deletion could cause operational downtime, affecting customer trust and revenue. Additionally, the reputational damage from a publicized breach could have long-term business consequences. Given the criticality and ease of exploitation, European entities using this system must prioritize addressing this vulnerability to prevent potential large-scale attacks.

1. Immediate implementation of input validation and parameterized queries (prepared statements) in the edit-ticket.php script to sanitize the 'tprice' POST parameter and prevent SQL injection. 2. Conduct a thorough code audit of the entire PHPGurukul Park Ticketing Management System to identify and remediate other potential injection points. 3. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'tprice' parameter and related endpoints. 4. Monitor web server and database logs for unusual query patterns or repeated failed attempts indicative of exploitation attempts. 5. Isolate the ticketing system network segment to limit lateral movement in case of compromise. 6. Engage with the vendor or community to obtain or develop patches and apply them promptly once available. 7. Educate development teams on secure coding practices, emphasizing the importance of input sanitization and use of ORM or parameterized queries. 8. Implement regular vulnerability scanning and penetration testing focused on injection vulnerabilities to proactively detect issues.
