The vulnerability identified as CVE-2017-17604 affects the Entrepreneur Bus Booking Script version 3.0.4, representing a critical SQL injection flaw that compromises the application's database security. This vulnerability resides within the booker_details.php script where the sourcebus parameter is improperly handled, allowing malicious actors to inject arbitrary SQL commands into the database query execution process. The flaw enables unauthorized access to sensitive data through direct database manipulation, potentially exposing confidential information about bus bookings, customer details, and system configurations.
The technical implementation of this vulnerability follows the classic SQL injection pattern where user input from the sourcebus parameter is directly concatenated into SQL queries without proper sanitization or parameterization. This creates an attack surface where an adversary can manipulate the SQL command structure by injecting malicious payloads such as single quotes, semicolons, or union select statements. The vulnerability aligns with CWE-89, which classifies improper neutralization of special elements used in SQL commands as a fundamental weakness in application security. Attackers can leverage this flaw to extract data, modify database contents, or even escalate privileges within the system.
The operational impact of this vulnerability extends beyond simple data theft, as it represents a severe compromise of the application's integrity and confidentiality. Successful exploitation could lead to complete database compromise, allowing attackers to view, alter, or delete critical booking information. The vulnerability affects the core functionality of the bus booking system, potentially disrupting service availability and creating financial losses for the business. From an attacker's perspective, this vulnerability maps to ATT&CK technique T1071.004 for application layer protocol manipulation, where database interaction is exploited for information gathering and system compromise.
Mitigation strategies for CVE-2017-17604 must focus on implementing proper input validation and parameterized queries to prevent SQL injection attacks. Organizations should immediately upgrade to the latest version of the Entrepreneur Bus Booking Script where this vulnerability has been patched. The remediation process involves implementing prepared statements or parameterized queries for all database interactions, particularly for the sourcebus parameter in booker_details.php. Additional protective measures include input sanitization, output encoding, and implementing proper access controls. Network-level protections such as web application firewalls should be deployed to monitor and block suspicious SQL injection patterns. Regular security audits and code reviews should be conducted to identify similar vulnerabilities in other application components, ensuring comprehensive protection against database injection attacks. The vulnerability demonstrates the importance of following secure coding practices and maintaining up-to-date software versions to prevent exploitation of known security flaws.
