CVE-2025-6890 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Movie Ticketing System. The vulnerability arises from improper sanitization or validation of the 'Date' argument processed by the /ticketConfirmation.php file. An attacker can remotely manipulate this parameter to inject malicious SQL code into the backend database queries. This injection can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the ticketing system's data. The vulnerability does not require user interaction and can be exploited without authentication, increasing the risk of automated or widespread attacks. Although the CVSS 4.0 score rates this vulnerability as medium (5.3), the presence of remote exploitation without authentication and the critical nature of SQL Injection vulnerabilities warrant careful attention. The exploit has been publicly disclosed, which may increase the likelihood of exploitation attempts, although no known exploits in the wild have been reported yet. The absence of available patches or mitigation links suggests that organizations using this software must take immediate protective measures.

For European organizations using the code-projects Movie Ticketing System 1.0, this vulnerability poses a significant risk to their operational security and customer data privacy. Exploitation could lead to unauthorized access to sensitive customer information, including booking details and potentially payment data if stored within the same database. This could result in data breaches subject to GDPR regulations, leading to legal penalties and reputational damage. Additionally, attackers could manipulate ticketing data, causing service disruptions, financial losses, and erosion of customer trust. Given the critical role of ticketing systems in entertainment and event management sectors, exploitation could also impact business continuity. The medium severity rating suggests that while the vulnerability is serious, exploitation may require some conditions or may have limited impact compared to higher severity SQL injections; however, the lack of authentication and remote exploitability increases the risk profile. European organizations must consider these impacts in the context of regulatory compliance and customer data protection obligations.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Applying strict input validation and sanitization on the 'Date' parameter at the web application firewall (WAF) or reverse proxy level to block malicious SQL payloads. 2) Employing parameterized queries or prepared statements within the application code to prevent SQL injection if source code access and modification are possible. 3) Restricting database user privileges to the minimum necessary to limit the impact of any successful injection. 4) Monitoring and logging all access to /ticketConfirmation.php and the 'Date' parameter for unusual or suspicious activity. 5) Conducting regular security assessments and penetration testing focused on injection vulnerabilities. 6) Planning for an urgent update or migration to a patched version once available. 7) Educating development and operations teams about secure coding practices and the risks of SQL injection. These targeted measures go beyond generic advice by focusing on the specific vulnerable parameter and the operational context of the affected system.
