CVE-2024-42771 identifies a stored Cross-Site Scripting (XSS) vulnerability in the Kashipara Hotel Management System version 1.0. The vulnerability exists in the /admin/edit_room_controller.php script, where the room_name parameter is improperly sanitized, allowing an authenticated attacker with high privileges to inject malicious JavaScript code that is stored on the server and executed in the browsers of other users who access the affected page. Stored XSS is particularly dangerous because the malicious payload persists on the server and can affect multiple users over time. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N) indicates that the attack is network exploitable with low attack complexity but requires high privileges and user interaction, and it affects confidentiality and integrity with a scope change but does not impact availability. The vulnerability is categorized under CWE-79, which covers improper neutralization of input during web page generation. No patches or known exploits have been reported yet, but the vulnerability could be leveraged to steal session cookies, perform actions on behalf of other users, or deliver further malware. The lack of a patch means organizations must rely on immediate mitigation strategies until an official fix is released.

The primary impact of this vulnerability is on confidentiality and integrity within affected systems. An attacker exploiting this flaw can execute arbitrary scripts in the context of other authenticated users, potentially leading to session hijacking, credential theft, or unauthorized administrative actions. Although availability is not affected, the compromise of administrative accounts or sensitive data could lead to broader organizational risks, including data breaches or operational disruptions. Since exploitation requires high privileges and user interaction, the risk is somewhat contained but still significant for organizations relying on this system for hotel management. The persistence of the stored XSS payload increases the attack surface over time, potentially affecting multiple users and amplifying damage. Organizations worldwide using Kashipara Hotel Management System v1.0 are at risk, especially those with multiple administrators accessing the vulnerable endpoint.

To mitigate this vulnerability, organizations should immediately implement strict input validation and output encoding on the room_name parameter within the /admin/edit_room_controller.php script to neutralize malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Limit administrative access to trusted personnel and enforce multi-factor authentication to reduce the risk of credential compromise. Regularly audit and sanitize stored data to remove any injected malicious scripts. Monitor logs for unusual activities related to the affected endpoint. Until an official patch is released, consider isolating or restricting access to the vulnerable admin interface. Additionally, educate administrators about the risks of clicking on suspicious links or executing untrusted scripts. Finally, maintain up-to-date backups to recover quickly if an incident occurs.
