CVE-2024-46077 identifies a Cross Site Scripting (XSS) vulnerability in itsourcecode Online Tours and Travels Management System version 1.0. The vulnerability arises from improper input validation in the travellers.php script, specifically within the parameters val-username, val-email, val-suggestions, val-digits, and state_name. These parameters accept user-supplied data without adequate sanitization or encoding, enabling attackers to inject malicious JavaScript payloads. When a victim user accesses a crafted URL or submits manipulated input, the injected script executes in their browser context. This can lead to theft of session cookies, defacement, or unauthorized actions performed on behalf of the user. The CVSS 3.1 vector indicates the attack can be performed remotely over the network (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect components beyond the vulnerable module. The impact on confidentiality and integrity is low (C:L/I:L), with no impact on availability (A:N). No patches or exploits are currently documented, but the vulnerability is publicly disclosed and should be addressed promptly. This vulnerability falls under CWE-79, a common category for XSS issues. Organizations running this software should review and harden input validation mechanisms to prevent exploitation.

The primary impact of CVE-2024-46077 is the potential compromise of user confidentiality and integrity within the affected Online Tours and Travels Management System. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users, leading to session hijacking, credential theft, or unauthorized actions such as modifying travel bookings or user data. While availability is not affected, the breach of confidentiality and integrity can damage customer trust and lead to regulatory compliance issues, especially in jurisdictions with strict data protection laws. For organizations operating in the travel and tourism sector, exploitation could result in reputational damage and financial losses due to fraud or service disruption. The requirement for some privileges and user interaction reduces the ease of exploitation but does not eliminate risk, especially in environments with multiple user roles and frequent user engagement. Since no known exploits are reported yet, the threat is currently theoretical but could increase if exploit code becomes available.

To mitigate CVE-2024-46077, organizations should implement strict input validation and output encoding on all user-supplied data, especially for the val-username, val-email, val-suggestions, val-digits, and state_name parameters in travellers.php. Employ a whitelist approach for allowed characters and reject or sanitize any suspicious input. Use security libraries or frameworks that automatically handle XSS protection. Enable Content Security Policy (CSP) headers to restrict script execution sources. Conduct thorough code reviews and penetration testing focusing on injection points. Limit privileges of users to the minimum necessary to reduce attack surface. Monitor web application logs for unusual input patterns or errors indicative of attempted exploitation. If possible, isolate the vulnerable application behind a Web Application Firewall (WAF) configured to detect and block XSS payloads. Stay alert for vendor patches or updates and apply them promptly once available. Educate users about phishing and suspicious links to reduce the risk of user interaction with malicious payloads.
