CVE-2025-4808 is a SQL Injection vulnerability identified in version 2.0 of the PHPGurukul Park Ticketing Management System, specifically within the /add-normal-ticket.php file. The vulnerability arises from improper sanitization or validation of input parameters such as 'noadult', 'nochildren', 'aprice', and 'cprice'. An attacker can manipulate these parameters to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. The vulnerability is remotely exploitable without requiring user interaction or authentication, which increases its risk profile. Although the CVSS 4.0 base score is 5.3 (medium severity), the vulnerability impacts confidentiality, integrity, and availability to a limited extent, as indicated by the CVSS vector: network attack vector, low attack complexity, no privileges or user interaction required, and low impact on confidentiality, integrity, and availability. No public exploits are currently known in the wild, and no patches have been published yet. However, the disclosure of the vulnerability means that attackers could develop exploits, especially since other parameters might also be vulnerable, increasing the attack surface. SQL Injection vulnerabilities can lead to data leakage, unauthorized data manipulation, or denial of service, depending on the attacker's goals and the database's role in the system.

For European organizations using the PHPGurukul Park Ticketing Management System version 2.0, this vulnerability poses a risk of unauthorized data access or manipulation, which could compromise customer data, ticketing information, and financial transactions. Given that ticketing systems often handle personal identifiable information (PII) and payment details, exploitation could lead to data breaches subject to GDPR regulations, resulting in legal and financial penalties. Additionally, manipulation of ticketing data could disrupt business operations, causing revenue loss and reputational damage. The medium severity rating suggests that while the vulnerability is exploitable remotely without authentication, the impact on critical systems may be limited, but still significant for organizations relying on this software for customer-facing services. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate future threats. European organizations should be particularly vigilant if they operate in tourism, event management, or public services sectors where such ticketing systems are deployed.

Organizations should immediately conduct a thorough audit of their PHPGurukul Park Ticketing Management System installations to identify affected versions. Since no official patches are currently available, temporary mitigations include implementing web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the vulnerable parameters ('noadult', 'nochildren', 'aprice', 'cprice'). Input validation and sanitization should be enforced at the application level, ideally by applying parameterized queries or prepared statements to prevent SQL injection. Monitoring and logging of unusual database queries or application errors related to ticketing operations should be enhanced to detect potential exploitation attempts. Organizations should also restrict database user permissions to the minimum necessary to limit the impact of a successful injection. Finally, maintain close communication with the vendor for patch releases and apply updates promptly once available.
