CVE-2024-51075 identifies a reflected Cross Site Scripting (XSS) vulnerability in the PHPGurukul Online DJ Booking Management System version 1.0. The flaw exists in the /odms/admin/user-search.php script, where the searchdata parameter is improperly sanitized, allowing attackers to inject malicious JavaScript code that is reflected back in the HTTP response. When a victim clicks a crafted URL containing malicious payloads in the searchdata parameter, the injected script executes within the victim's browser context. This can lead to theft of session cookies, user impersonation, or unauthorized actions performed with the victim's privileges. The vulnerability requires no authentication but does require user interaction, such as clicking a malicious link. The CVSS 3.1 base score is 6.1, indicating a medium severity level due to the network attack vector, low attack complexity, no privileges required, but user interaction needed. The scope is changed (S:C) because the vulnerability affects components beyond the initially vulnerable component, potentially impacting the entire user session. No known public exploits or patches have been published yet, which means organizations must proactively implement mitigations. The vulnerability is categorized under CWE-79, which covers improper neutralization of input during web page generation leading to XSS.

This vulnerability can have significant impacts on organizations using the PHPGurukul Online DJ Booking Management System. Successful exploitation allows attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of users. This compromises confidentiality and integrity of user data and can lead to further compromise of the affected system or network. Since the vulnerability is reflected XSS, the attacker must trick users into clicking malicious links, which can be done via phishing or social engineering. The impact is particularly critical for administrative users who have elevated privileges, as their accounts could be fully compromised. Although availability is not directly affected, the breach of confidentiality and integrity can lead to reputational damage, regulatory penalties, and operational disruptions. Organizations with public-facing instances of this system are at higher risk, especially if they do not implement additional security controls such as Content Security Policy (CSP) or input validation.

To mitigate CVE-2024-51075, organizations should implement strict input validation and output encoding on the searchdata parameter to ensure that any user-supplied data is properly sanitized before being reflected in the web page. Employing context-aware output encoding (e.g., HTML entity encoding) prevents execution of injected scripts. Implementing a robust Content Security Policy (CSP) can help restrict the execution of unauthorized scripts. Additionally, user input should be validated on the server side to reject suspicious or malformed input. Organizations should monitor web application logs for suspicious requests targeting the searchdata parameter. Since no official patch is available, consider applying web application firewalls (WAFs) with rules to detect and block XSS payloads targeting this endpoint. Educate users, especially administrators, about phishing risks and encourage cautious behavior regarding clicking unknown links. Finally, maintain an incident response plan to quickly address any exploitation attempts.
