CVE-2025-14200 is a cross-site scripting vulnerability identified in the alokjaiswal Hotel-Management-services-using-MYSQL-and-php application, affecting the /usersub.php file within the Request Pending Page component. The vulnerability arises from improper input sanitization or output encoding, allowing an attacker to inject malicious JavaScript code remotely. The attack vector requires no authentication but does require user interaction to execute the malicious payload, such as a user visiting a crafted URL or interacting with manipulated page content. The vulnerability has a CVSS 4.0 score of 5.1, indicating medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, but user interaction necessary. The impact primarily affects confidentiality and integrity by enabling attackers to steal session cookies, perform actions on behalf of users, or deliver further malware. The product follows a rolling release model, complicating patch management as no fixed version updates are available. The vendor has not responded to vulnerability disclosure, and no official patches or mitigations have been published. Although no active exploitation in the wild is currently known, the public disclosure of the exploit code increases the risk of opportunistic attacks. This vulnerability is particularly concerning for organizations managing sensitive customer data and booking information within the hospitality sector.

For European organizations, exploitation of this XSS vulnerability could lead to significant data breaches involving customer personal information, booking details, and payment data, undermining confidentiality and user trust. Attackers could hijack user sessions, impersonate legitimate users, or conduct phishing attacks leveraging the compromised application interface. This could result in regulatory non-compliance under GDPR due to unauthorized data exposure. The integrity of booking and management data could be compromised, potentially disrupting hotel operations and causing financial losses. Availability impact is limited but could arise indirectly through follow-on attacks or exploitation of stolen credentials. The hospitality industry in Europe is a frequent target for cyberattacks, and organizations using this vulnerable software may face reputational damage and legal consequences if exploited. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls.

European organizations should immediately conduct a thorough audit of their deployment of the alokjaiswal Hotel-Management-services-using-MYSQL-and-php software to identify affected instances. Since no official patches are available, implement strict input validation and output encoding on the /usersub.php page to neutralize malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Use web application firewalls (WAFs) to detect and block common XSS attack patterns targeting the vulnerable endpoint. Educate users about the risks of clicking on suspicious links and encourage the use of multi-factor authentication to reduce session hijacking risks. Monitor logs for unusual activity indicative of exploitation attempts. Consider isolating or replacing the vulnerable component with a more secure alternative if feasible. Engage with the vendor or community to track any forthcoming patches or updates. Regularly update all related software components and dependencies to minimize exposure to other vulnerabilities.
