CVE-2024-42776 identifies an incorrect access control vulnerability in Kashipara Hotel Management System version 1.0, specifically affecting the /admin/users.php page. This vulnerability falls under CWE-284, which relates to improper authorization checks. The flaw allows authenticated users with high privileges to bypass intended access restrictions, potentially enabling unauthorized actions such as viewing, modifying, or deleting user accounts or administrative data. The CVSS v3.1 base score is 7.2, indicating a high severity level. The vector metrics specify that the attack can be performed remotely (AV:N) with low attack complexity (AC:L), but requires privileges (PR:H) and no user interaction (UI:N). The impact affects confidentiality, integrity, and availability (C:H/I:H/A:H), meaning that successful exploitation could lead to full compromise of sensitive data and system functions. No patches or known exploits are currently available, which means organizations must rely on compensating controls. The vulnerability is critical because it undermines the core security principle of access control in an administrative context, potentially allowing privilege escalation or unauthorized administrative operations.

The vulnerability could lead to unauthorized access or modification of sensitive administrative user data, compromising the confidentiality and integrity of the hotel management system. Attackers with high privileges might escalate their access or perform unauthorized administrative actions, potentially disrupting hotel operations or exposing customer data. This could result in data breaches, operational downtime, financial losses, and reputational damage. Since the vulnerability affects a hotel management system, the impact extends to guest privacy and compliance with data protection regulations. The availability impact could manifest if attackers disrupt administrative functions or delete critical user accounts. Organizations worldwide using Kashipara Hotel Management System v1.0 are at risk, especially those with remote administrative access enabled.

Until an official patch is released, organizations should implement strict network segmentation to restrict access to the /admin/users.php endpoint only to trusted administrative hosts. Employ multi-factor authentication (MFA) for all privileged accounts to reduce the risk of credential compromise. Conduct thorough audits of user privileges and remove any unnecessary high-level access. Monitor logs for unusual administrative activity or access patterns. If possible, disable remote administrative access or restrict it via VPN with strong authentication. Consider deploying web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts to the vulnerable endpoint. Engage with the vendor for timely updates and apply patches immediately once available. Additionally, conduct penetration testing focused on access control to identify any other potential weaknesses.
