The vulnerability identified as CVE-2017-17633 affects the Multiplex Movie Theater Booking Script version 3.1.5, presenting a critical SQL injection flaw that compromises the database integrity and confidentiality of the affected system. This vulnerability stems from insufficient input validation and sanitization within the script's web interface, specifically targeting three distinct parameters across different php files. The affected parameters include moid in trailer-detail.php, moid in show-time.php, and eid in event-detail.php, all of which are susceptible to malicious input manipulation that can bypass normal authentication and authorization mechanisms. The vulnerability allows attackers to inject arbitrary SQL commands through these parameters, potentially gaining unauthorized access to sensitive data stored within the database.
The technical implementation of this vulnerability follows the classic SQL injection attack pattern where user-controllable input directly influences database query construction without proper sanitization or parameterization. When an attacker submits malicious input through any of the three vulnerable parameters, the application fails to properly escape or validate the input before incorporating it into SQL queries. This oversight creates an opportunity for attackers to manipulate the intended query execution flow, potentially allowing them to extract, modify, or delete database records. The CWE-89 identifier applies to this vulnerability as it represents a classic SQL injection flaw where untrusted data is directly concatenated into SQL commands without proper escaping or parameterization techniques.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to escalate privileges and gain administrative control over the booking system. An attacker could potentially extract customer information, booking details, payment records, and other sensitive data that the theater management considers confidential. The vulnerability also opens pathways for data corruption and system disruption, potentially allowing attackers to manipulate show times, booking availability, and other critical operational parameters. This risk is particularly concerning in a movie theater booking environment where personal information and financial data are routinely processed and stored within the system.
Organizations utilizing this vulnerable software should immediately implement comprehensive mitigations to protect against exploitation attempts. The primary defense mechanism involves implementing proper input validation and parameterized queries throughout the application code, ensuring that all user-supplied data undergoes rigorous sanitization before being processed in database operations. The implementation of prepared statements and stored procedures should be mandatory across all database interactions to prevent direct concatenation of user input with SQL commands. Additionally, network-level protections including web application firewalls and intrusion detection systems should be deployed to monitor for suspicious query patterns and potential exploitation attempts. Regular security audits and penetration testing should be conducted to identify and remediate similar vulnerabilities throughout the application infrastructure. The ATT&CK framework categorizes this vulnerability under the T1190 technique for exploiting vulnerabilities in web applications, emphasizing the need for proper input validation and secure coding practices to prevent such exploitation vectors from compromising system integrity and data confidentiality.
