CVE-2024-42767 identifies a critical security flaw in Kashipara Hotel Management System version 1.0, specifically an Unrestricted File Upload vulnerability located in the /admin/add_room_controller.php script. This vulnerability allows an attacker possessing administrative privileges to upload arbitrary files without proper validation or restriction. The lack of file type or content validation enables the attacker to upload malicious scripts or executables, leading to remote code execution (RCE) on the server hosting the application. The vulnerability is categorized under CWE-434, which concerns improper restrictions on file uploads. The CVSS 3.1 score of 7.2 indicates a high-severity issue with network attack vector (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Although exploitation requires authenticated administrative access, the impact of successful exploitation is severe, potentially allowing full system compromise. No patches or official fixes have been published yet, and no known exploits are reported in the wild. The vulnerability emphasizes the need for secure file upload handling and strict access controls within web applications, especially those managing critical business functions like hotel management.

The impact of CVE-2024-42767 is significant for organizations using Kashipara Hotel Management System v1.0. Successful exploitation allows attackers with administrative credentials to upload malicious files, resulting in remote code execution. This can lead to full system compromise, data theft, unauthorized modification of records, service disruption, and potential lateral movement within the network. Confidential customer data, including personal and payment information, could be exposed or altered, damaging organizational reputation and incurring regulatory penalties. The availability of the hotel management system could be disrupted, affecting operational continuity and customer service. Since the vulnerability requires high privileges, the risk is somewhat mitigated by the need for administrative access; however, if credentials are compromised or weak, the threat becomes critical. The absence of known exploits currently provides a window for remediation, but the vulnerability remains a high risk due to its potential for severe damage.

To mitigate CVE-2024-42767, organizations should immediately restrict administrative access to the Kashipara Hotel Management System by enforcing strong authentication mechanisms such as multi-factor authentication (MFA) and limiting access to trusted personnel only. Implement network segmentation and firewall rules to restrict access to the admin interface. Since no official patches are available, organizations should consider disabling or restricting the /admin/add_room_controller.php endpoint temporarily if feasible. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious file upload attempts. Conduct thorough input validation and implement server-side file type and content verification to prevent malicious uploads. Monitor logs for unusual file upload activity and signs of exploitation. Regularly audit user privileges to ensure the principle of least privilege is enforced. Finally, maintain up-to-date backups and have an incident response plan ready to address potential compromises.
