CVE-2025-25775 is a critical SQL injection vulnerability identified in the Codeastro Bus Ticket Booking System version 1.0. The vulnerability exists in the 'kodetiket' parameter within the endpoint '/BusTicket-CI/tiket/cekorder'. An attacker can exploit this flaw by injecting malicious SQL code through this parameter, which is not properly sanitized or validated by the application. This allows the attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or deletion. Given the CVSS 3.1 base score of 9.8, the vulnerability is remotely exploitable over the network without requiring any authentication or user interaction. The impact covers confidentiality, integrity, and availability of the affected system, as attackers can exfiltrate sensitive information, alter ticket booking data, or disrupt service availability. Although no public exploits have been reported yet, the ease of exploitation and the critical nature of the flaw make it a high-risk threat. The vulnerability is classified under CWE-89, which corresponds to SQL Injection, a well-known and widely exploited attack vector. The absence of vendor or product-specific information limits precise identification, but the affected system is clearly the Codeastro Bus Ticket Booking System v1.0. The lack of available patches or mitigations at the time of publication increases the urgency for organizations using this system to implement protective controls immediately.

For European organizations using the Codeastro Bus Ticket Booking System, this vulnerability poses a severe risk. Exploitation could lead to unauthorized disclosure of passenger data, including personal and payment information, violating GDPR and other data protection regulations. Integrity of booking records could be compromised, leading to fraudulent ticket issuance or cancellations, impacting revenue and customer trust. Availability disruptions could cause service outages, affecting operational continuity and customer satisfaction. Transportation and travel companies relying on this system could face reputational damage and regulatory penalties. Additionally, attackers could leverage the compromised system as a foothold for lateral movement within the network, potentially escalating attacks to other critical infrastructure components. The criticality of public transport and ticketing systems in Europe amplifies the potential societal and economic impact of such an attack.

Given the absence of official patches, European organizations should immediately implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'kodetiket' parameter, including payload patterns typical for SQLi. 2) Conduct thorough input validation and sanitization on all user-supplied data, especially the 'kodetiket' parameter, using parameterized queries or prepared statements to prevent injection. 3) Restrict database user privileges to the minimum necessary, avoiding use of high-privilege accounts for application database access to limit the impact of successful injection. 4) Monitor database logs and application logs for anomalous queries or error messages indicative of injection attempts. 5) Isolate the ticket booking system network segment to reduce exposure and prevent lateral movement. 6) Prepare incident response plans specific to SQL injection exploitation scenarios. 7) Engage with the vendor or software maintainer to obtain patches or updates as soon as they become available. 8) Consider temporary alternative ticketing solutions if mitigation cannot be assured promptly.
