CVE-2022-41416 is a high-severity SQL injection vulnerability identified in the Online Tours & Travels Management System version 1.0. The vulnerability exists in the 'id' parameter of the /user/update_booking.php endpoint. SQL injection (CWE-89) occurs when untrusted input is improperly sanitized and directly included in SQL queries, allowing an attacker to manipulate the backend database. In this case, the 'id' parameter is vulnerable, enabling an attacker with high privileges (PR:H) to execute arbitrary SQL commands remotely (AV:N) without requiring user interaction (UI:N). The vulnerability affects confidentiality, integrity, and availability (C:H/I:H/A:H) of the system, as an attacker could extract sensitive data, modify or delete records, or disrupt service. The CVSS v3.1 base score is 7.2, reflecting the ease of exploitation due to low attack complexity (AC:L) and the significant impact on the system. Although no known exploits are reported in the wild, the vulnerability poses a serious risk to any organization using this software, especially given the lack of available patches. The Online Tours & Travels Management System is a niche product, but its use in travel and booking services means that compromised systems could lead to exposure of personal customer data, financial information, and disruption of booking operations.

For European organizations, this vulnerability could lead to severe consequences including unauthorized access to customer personal and payment data, manipulation or cancellation of bookings, and potential service outages. The travel and tourism sector is critical in Europe, contributing significantly to the economy and involving numerous SMEs and large enterprises. A successful attack exploiting this SQL injection could result in regulatory penalties under GDPR due to data breaches, reputational damage, and financial losses. Additionally, disruption of booking systems could impact customer trust and operational continuity. Given the high privileges required, the threat is more relevant to insiders or attackers who have already gained some level of access, but the network-exploitable nature means lateral movement could be facilitated. The absence of patches increases the risk of exploitation if the software is still in use without mitigation.

Organizations using the Online Tours & Travels Management System v1.0 should immediately audit their use of the /user/update_booking.php endpoint and the 'id' parameter for SQL injection vulnerabilities. Specific mitigations include: 1) Implementing parameterized queries or prepared statements to prevent SQL injection; 2) Applying strict input validation and sanitization on all user-supplied data, especially the 'id' parameter; 3) Restricting database user permissions to the minimum necessary to limit impact if exploited; 4) Monitoring logs for suspicious SQL errors or unusual database activity; 5) If possible, isolating the vulnerable system from external networks or applying web application firewalls (WAF) with SQL injection detection rules; 6) Considering migration to a more secure and actively maintained booking system if patches are unavailable; 7) Conducting regular security assessments and penetration tests focusing on injection flaws. Since no official patch is available, these compensating controls are critical to reduce risk.
