CVE-2025-4777 is a SQL Injection vulnerability identified in version 2.0 of the PHPGurukul Park Ticketing Management System, specifically within the /view-foreigner-ticket.php file. The vulnerability arises from improper sanitization or validation of the 'viewid' parameter, which is susceptible to malicious SQL payloads. An attacker can remotely exploit this flaw without authentication or user interaction, sending crafted requests that manipulate the SQL query executed by the backend database. This can lead to unauthorized data access, data modification, or potentially database compromise depending on the underlying database permissions and structure. The CVSS 4.0 base score is 5.3, indicating a medium severity level, with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is rated low individually, suggesting limited but non-negligible risk. No patches or fixes have been publicly linked yet, and no known exploits are reported in the wild, though public disclosure of the exploit code increases the risk of exploitation attempts.

For European organizations using the PHPGurukul Park Ticketing Management System 2.0, this vulnerability could lead to unauthorized access to sensitive ticketing data, including customer information and transaction details. While the impact on confidentiality, integrity, and availability is rated low individually, successful exploitation could allow attackers to extract or manipulate data, potentially leading to privacy violations under GDPR and damaging customer trust. The remote and unauthenticated nature of the exploit increases the risk of automated attacks or targeted exploitation. Organizations operating public-facing ticketing portals are particularly at risk, as attackers could leverage this vulnerability to gain footholds or pivot to other internal systems. The lack of available patches necessitates immediate mitigation to prevent data breaches and comply with European data protection regulations.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include: 1) Applying Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'viewid' parameter; 2) Conducting thorough input validation and sanitization on all user-supplied parameters, especially 'viewid', to reject or neutralize malicious input; 3) Restricting database user permissions to the minimum necessary to limit the impact of a successful injection; 4) Monitoring web server and database logs for unusual query patterns or errors indicative of injection attempts; 5) Isolating the ticketing system network segment to reduce lateral movement risk; 6) Planning and prioritizing an upgrade or patch deployment once an official fix is released by PHPGurukul; 7) Educating IT and security teams on the vulnerability details to enhance detection and response capabilities.
