CVE-2024-44728 identifies a stored Cross-Site Scripting (XSS) vulnerability in Sourcecodehero Event Management System version 1.0. The vulnerability exists in the /clientdetails/admin/regester.php endpoint, where user-supplied input fields such as Full Name, Address, Email, and contact# are not properly sanitized or encoded before being stored and rendered back to users. This flaw allows an attacker with at least low-level privileges to inject malicious JavaScript code that is persistently stored on the server and executed in the browsers of other users who view the affected pages. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. According to the CVSS v3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N), the attack can be launched remotely over the network with low attack complexity, requires low privileges and user interaction, and affects confidentiality with high impact, integrity with low impact, and no impact on availability. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. No patches or public exploits have been reported yet, but the risk remains significant due to the potential for session hijacking, credential theft, or other malicious activities leveraging the stored XSS. The lack of input validation and output encoding in critical user input fields is the root cause.

The primary impact of CVE-2024-44728 is on the confidentiality of user data and session information within the Sourcecodehero Event Management System. Successful exploitation can lead to theft of sensitive information such as authentication tokens, personal data, or administrative credentials, enabling further unauthorized access or privilege escalation. Although the integrity impact is rated low, attackers could manipulate displayed content or perform actions on behalf of other users, potentially undermining trust and operational integrity. Availability is not affected directly. For organizations, this vulnerability could result in data breaches, unauthorized access to event management data, and reputational damage. Since the vulnerability requires authenticated access and user interaction, insider threats or compromised accounts increase risk. The absence of known exploits reduces immediate threat but does not eliminate the risk of future attacks, especially if the vulnerability is disclosed publicly without a patch.

To mitigate CVE-2024-44728, organizations should implement strict input validation and output encoding on all user-supplied data fields, especially Full Name, Address, Email, and contact# parameters in the /clientdetails/admin/regester.php page. Employ context-aware encoding (e.g., HTML entity encoding) before rendering data in the browser to prevent script execution. Enforce the principle of least privilege to limit the ability of low-privilege users to inject malicious content. Conduct thorough code reviews and security testing focusing on stored XSS vectors. If possible, deploy Web Application Firewalls (WAFs) with rules to detect and block XSS payloads targeting these parameters. Monitor logs for suspicious input patterns and anomalous user behavior. Until an official patch is available, consider disabling or restricting access to the vulnerable functionality for non-trusted users. Educate administrators and users about the risks of clicking on suspicious links or executing untrusted scripts. Finally, maintain an incident response plan to quickly address any exploitation attempts.
