CVE-2025-4770 is a SQL Injection vulnerability identified in version 2.0 of the PHPGurukul Park Ticketing Management System, specifically within the /view-normal-ticket.php file. The vulnerability arises due to improper sanitization or validation of the 'viewid' parameter, which is used in SQL queries. An attacker can manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. This can lead to data leakage, data corruption, or unauthorized administrative actions. The vulnerability is remotely exploitable without requiring user interaction or authentication, increasing its risk profile. Although the CVSS 4.0 score is rated medium (5.3), the vulnerability's impact on confidentiality, integrity, and availability is limited to low or partial, as indicated by the CVSS vector. No known exploits are currently reported in the wild, and no official patches have been published yet. The vulnerability was publicly disclosed on May 16, 2025, and affects only version 2.0 of the product. The PHPGurukul Park Ticketing Management System is a specialized application used for managing ticket sales and entry for parks, implying that the affected systems are likely deployed in recreational or tourism sectors.

For European organizations, especially those involved in tourism, park management, or event ticketing, exploitation of this vulnerability could lead to unauthorized access to customer data, including personal and payment information stored in the backend database. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Additionally, attackers might manipulate ticketing data, causing operational disruptions such as invalid ticket issuance or denial of service to legitimate customers. Although the vulnerability does not currently have known exploits in the wild, the public disclosure increases the risk of exploitation attempts. The medium severity rating suggests that while the threat is significant, it may not lead to full system compromise or widespread disruption without additional vulnerabilities or misconfigurations.

Organizations using PHPGurukul Park Ticketing Management System 2.0 should immediately conduct a thorough security review of the /view-normal-ticket.php endpoint, focusing on input validation and parameter sanitization for the 'viewid' argument. Implement prepared statements or parameterized queries to prevent SQL injection. If possible, restrict access to the affected endpoint via network controls or web application firewalls (WAF) with specific rules to detect and block SQL injection patterns targeting 'viewid'. Monitor logs for suspicious activities related to this parameter. Since no official patch is currently available, consider isolating the ticketing system from public networks or deploying it behind VPNs or reverse proxies with strict access controls. Regularly back up the database and have an incident response plan ready in case of compromise. Engage with the vendor for timely patch releases and updates.
