CVE-2025-4153 is a critical SQL Injection vulnerability identified in version 2.0 of the PHPGurukul Park Ticketing Management System, specifically within the /profile.php file. The vulnerability arises from improper sanitization or validation of the 'adminname' parameter, which can be manipulated remotely by an unauthenticated attacker to inject malicious SQL queries. This flaw allows attackers to interfere with the backend database queries executed by the application. Exploiting this vulnerability can lead to unauthorized data access, data modification, or even complete compromise of the underlying database. The vulnerability is remotely exploitable without requiring any authentication or user interaction, increasing its risk profile. Although the CVSS 4.0 score is 6.9 (medium severity), the nature of SQL injection vulnerabilities typically implies a significant risk to confidentiality, integrity, and availability of data. The vulnerability affects a specific version (2.0) of the PHPGurukul Park Ticketing Management System, a product used for managing ticket sales and user profiles in park management contexts. No official patches or mitigations have been published at the time of reporting, and while no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the likelihood of exploitation attempts.

For European organizations using the PHPGurukul Park Ticketing Management System 2.0, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized access to sensitive customer data, including personal information and payment details, potentially violating GDPR and other data protection regulations. Data integrity could be compromised, allowing attackers to alter ticketing records or user profiles, disrupting business operations and undermining trust. Availability of the ticketing system could also be affected if attackers execute destructive SQL commands or cause database corruption, leading to service outages and financial losses. Given the critical role of ticketing systems in public venues and events, exploitation could disrupt operations at parks, cultural sites, or recreational facilities, impacting customer experience and revenue. Additionally, the remote, unauthenticated nature of the exploit increases the attack surface, making it easier for cybercriminals to target these systems without insider access or user interaction.

1. Immediate application of input validation and parameterized queries (prepared statements) in the /profile.php file to prevent SQL injection. 2. If available, upgrade to a patched version of the PHPGurukul Park Ticketing Management System; if no patch exists, consider disabling or restricting access to the vulnerable functionality until a fix is released. 3. Implement web application firewalls (WAF) with rules specifically designed to detect and block SQL injection attempts targeting the 'adminname' parameter. 4. Conduct thorough code audits and penetration testing focused on SQL injection vectors in all user input handling components. 5. Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 6. Monitor logs for suspicious database queries or repeated failed attempts targeting the vulnerable parameter. 7. Employ network segmentation to isolate the ticketing system from other critical infrastructure, reducing lateral movement risk. 8. Educate IT and security teams about this specific vulnerability and ensure rapid incident response capabilities are in place.
