CVE-2025-4778 is a SQL Injection vulnerability identified in version 2.0 of the PHPGurukul Park Ticketing Management System, specifically within the /normal-search.php file. The vulnerability arises from improper sanitization or validation of the 'searchdata' parameter, which is directly used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the underlying database. This could lead to unauthorized data retrieval, modification, or deletion, depending on the database permissions and the nature of the injected SQL commands. The vulnerability does not require user interaction or authentication, making it accessible to remote attackers without credentials. The CVSS 4.0 base score is 5.3, indicating a medium severity level, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:L), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is rated low, suggesting limited but non-negligible consequences if exploited. As of the published date, no public exploits have been observed in the wild, and no official patches have been released. However, the public disclosure of the vulnerability increases the risk of exploitation attempts.

For European organizations using the PHPGurukul Park Ticketing Management System 2.0, this vulnerability poses a risk of unauthorized database access. Potential impacts include leakage of sensitive customer data, such as personal information and ticketing details, which could lead to privacy violations under GDPR. Data integrity could be compromised if attackers modify ticketing records, potentially disrupting operations and causing financial losses. Availability impacts are likely minimal but could occur if attackers execute destructive SQL commands. Given the critical nature of ticketing systems in public venues, exploitation could also damage organizational reputation and customer trust. The medium severity rating suggests that while the vulnerability is exploitable remotely without authentication, the overall impact is somewhat limited, possibly due to constrained database permissions or partial sanitization. Nonetheless, European entities in the leisure, tourism, and event management sectors should consider this a significant risk, especially those relying on this specific software version.

Immediate mitigation should focus on input validation and sanitization of the 'searchdata' parameter to prevent SQL injection. Organizations should implement parameterized queries or prepared statements in the affected code to ensure user inputs are safely handled. In the absence of an official patch, applying web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting /normal-search.php can reduce exposure. Conduct thorough code reviews and penetration testing to identify similar injection points. Restrict database user permissions to the minimum necessary to limit potential damage. Monitor logs for unusual query patterns or repeated access attempts to the vulnerable endpoint. Finally, maintain communication with the vendor for patch releases and apply updates promptly once available.
