CVE-2024-42766 identifies an incorrect access control vulnerability in the Kashipara Bus Ticket Reservation System version 1.0.0, specifically within the /deleteTicket.php script. This vulnerability stems from insufficient authorization verification, allowing users with limited privileges (PR:L) to perform deletion operations on tickets that they should not be authorized to delete. The vulnerability is remotely exploitable over the network (AV:N) without requiring user interaction (UI:N). The CVSS v3.1 base score is 5.4, reflecting a medium severity level. The attack vector is network-based, with low attack complexity (AC:L), meaning an attacker with some level of authenticated access can exploit this flaw easily. The impact affects integrity and availability (I:L, A:L) but not confidentiality (C:N), as unauthorized deletion can disrupt service availability and compromise data integrity by removing legitimate ticket records. The vulnerability is categorized under CWE-284 (Improper Access Control), indicating a failure to enforce correct permissions. No patches or known exploits are currently available, highlighting the need for proactive mitigation. This vulnerability could be exploited by malicious insiders or attackers who have gained limited access to the system, enabling unauthorized ticket deletions that could disrupt operations or cause financial loss.

The primary impact of CVE-2024-42766 is on the integrity and availability of the Kashipara Bus Ticket Reservation System. Unauthorized deletion of tickets can lead to service disruptions, customer dissatisfaction, and potential financial losses due to improper ticket management. Organizations relying on this system may face operational challenges, including inaccurate ticketing data and potential denial of service for legitimate users. While confidentiality is not directly affected, the integrity compromise can undermine trust in the system. The ease of exploitation by authenticated users with limited privileges increases the risk of insider threats or lateral movement attacks. If exploited at scale, this vulnerability could impact the overall reliability of the ticket reservation service, affecting business continuity and customer experience.

To mitigate CVE-2024-42766, organizations should implement strict access control mechanisms on the /deleteTicket.php endpoint. This includes enforcing role-based access control (RBAC) to ensure only authorized users can delete tickets. Conduct a thorough code review and add server-side authorization checks that validate user permissions before processing deletion requests. Employ logging and monitoring to detect unauthorized deletion attempts promptly. If possible, implement multi-factor authentication (MFA) to reduce the risk of compromised credentials being used for exploitation. Regularly update and patch the system once vendor fixes become available. Additionally, consider implementing input validation and session management best practices to prevent privilege escalation. Conduct security testing, including penetration testing focused on access control flaws, to identify and remediate similar vulnerabilities proactively.
