CVE-2024-51076 identifies a reflected Cross-Site Scripting (XSS) vulnerability in the PHPGurukul Online DJ Booking Management System version 1.0. The vulnerability exists in the /odms/admin/booking-search.php script, specifically through the 'searchdata' GET or POST parameter, which fails to properly sanitize user-supplied input before reflecting it back in the web page response. This allows an attacker to craft a malicious URL containing JavaScript code that, when clicked by an administrator or user with access to the booking search page, executes arbitrary scripts within their browser context. The reflected XSS can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The vulnerability requires no authentication and only user interaction (clicking a malicious link). The CVSS 3.1 score of 6.1 reflects medium severity, with an attack vector of network, low attack complexity, no privileges required, user interaction required, and a scope change indicating that the vulnerability affects components beyond the initially vulnerable component. The impact includes limited confidentiality and integrity loss but no availability impact. No patches or official fixes have been released yet, and no active exploitation has been reported. The vulnerability is classified under CWE-79, a common web application security weakness related to improper neutralization of input. Organizations using this booking management system should urgently review their input validation and output encoding practices, and consider temporary mitigations such as web application firewall (WAF) rules to detect and block malicious payloads.

The reflected XSS vulnerability in PHPGurukul Online DJ Booking Management System 1.0 can lead to significant security risks for organizations relying on this software. Attackers can exploit this flaw to execute arbitrary JavaScript in the context of authenticated users, potentially stealing session cookies, performing unauthorized actions, or redirecting users to malicious sites. This compromises the confidentiality and integrity of user data and administrative functions. Although availability is not directly impacted, the breach of trust and potential data leakage can cause reputational damage and operational disruptions. Since the vulnerability requires user interaction but no authentication, phishing campaigns or social engineering can be effective attack vectors. Organizations in the entertainment, event management, and booking sectors using this system are at risk of targeted attacks, especially if they have high-value data or privileged users accessing the vulnerable endpoint. The lack of patches increases exposure duration, emphasizing the need for immediate mitigation.

To mitigate CVE-2024-51076, organizations should implement strict input validation and output encoding on the 'searchdata' parameter to neutralize malicious scripts. Employing context-aware encoding (e.g., HTML entity encoding) before reflecting user input in the web page is critical. If source code modification is not immediately feasible, deploying a Web Application Firewall (WAF) with custom rules to detect and block typical XSS payloads targeting the booking-search.php endpoint can reduce risk. Educate users and administrators about phishing risks and encourage cautious handling of URLs received via email or other channels. Monitoring web server logs for suspicious query parameters and unusual access patterns can help detect exploitation attempts. Organizations should also engage with PHPGurukul for official patches or updates and plan timely application once available. Additionally, consider implementing Content Security Policy (CSP) headers to restrict script execution sources, further mitigating XSS impact.
