CVE-2023-45015 in Online Bus Booking System
Summary
by MITRE • 11/02/2023
Online Bus Booking System v1.0 is vulnerable to multiple Unauthenticated SQL Injection vulnerabilities. The 'date' parameter of the bus_info.php resource does not validate the characters received and they are sent unfiltered to the database.

The Online Bus Booking System v1.0 presents a critical security vulnerability through multiple unauthenticated SQL injection flaws that directly compromise the underlying database infrastructure. This vulnerability specifically targets the bus_info.php resource where the 'date' parameter fails to implement proper input validation mechanisms, allowing malicious actors to inject arbitrary SQL commands directly into the database query execution process. The absence of input sanitization creates a direct pathway for attackers to manipulate database operations without requiring authentication credentials, making this vulnerability particularly dangerous as it can be exploited by anyone with access to the application interface.
This vulnerability aligns with CWE-89 which specifically addresses SQL injection weaknesses where insufficient validation of user-supplied data leads to unauthorized database access. The flaw represents a classic case of improper input handling where the application fails to properly escape or filter special characters that could alter the intended SQL query structure. The unfiltered 'date' parameter becomes a conduit for attackers to execute malicious SQL commands, potentially leading to data extraction, modification, or deletion operations that can fundamentally compromise the integrity and availability of the booking system's database.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete database compromise and potential system-wide disruption. Attackers could exploit this weakness to extract sensitive passenger information, manipulate booking records, modify pricing structures, or even gain administrative access to the system through database-level privileges. The unauthenticated nature of this vulnerability means that any individual can potentially exploit it without requiring legitimate credentials, amplifying the risk to both the organization and its customers who rely on the system for their travel arrangements. This vulnerability directly threatens the confidentiality, integrity, and availability of critical business data within the transportation booking ecosystem.
Mitigation strategies should focus on implementing robust input validation and parameterized queries to prevent SQL injection attacks. The system requires immediate implementation of proper input sanitization techniques where all user-supplied data, particularly the 'date' parameter, must undergo thorough validation before database processing. Organizations should deploy web application firewalls and input filtering mechanisms to detect and block suspicious SQL injection patterns. Additionally, regular security audits and penetration testing should be conducted to identify and remediate similar vulnerabilities throughout the application codebase. The implementation of principle of least privilege access controls and database query logging can further enhance detection capabilities and limit the potential damage from successful exploitation attempts. This vulnerability serves as a critical reminder of the importance of secure coding practices and the necessity of validating all user inputs against established security standards and frameworks.
