CVE-2024-42788 identifies a stored Cross Site Scripting (XSS) vulnerability in the Kashipara Music Management System version 1.0. The flaw exists in the /music/ajax.php endpoint when the action parameter is set to 'save_music'. Specifically, the 'title' and 'artist' input fields do not properly sanitize or encode user-supplied data before storing it. This allows an attacker to inject malicious JavaScript code that is persistently stored on the server and later executed in the browsers of users who view the affected content. The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). The CVSS 3.1 base score is 6.1, reflecting a medium severity level, with attack vector as network (remote), low attack complexity, no privileges required, but requiring user interaction. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component. The impact affects confidentiality and integrity by enabling arbitrary code execution in the victim’s browser context, potentially leading to session hijacking, credential theft, or unauthorized actions on behalf of the user. No patches or fixes have been published yet, and no known exploits have been reported in the wild. The vulnerability underscores the need for proper input validation, output encoding, and use of security headers to mitigate stored XSS risks in web applications.

The stored XSS vulnerability in Kashipara Music Management System can have significant impacts on organizations using this software. Attackers can inject malicious scripts that execute in the browsers of users who access the affected pages, potentially leading to session hijacking, theft of sensitive information such as cookies or credentials, and unauthorized actions performed with the victim’s privileges. This can compromise user accounts and lead to further network penetration or data breaches. Although the vulnerability does not directly affect system availability, the integrity and confidentiality of user data are at risk. The requirement for user interaction (e.g., visiting a maliciously crafted page) limits automated exploitation but does not eliminate risk, especially in environments with many users. Organizations relying on this system for music management or content delivery may face reputational damage and compliance issues if user data is compromised. The absence of a patch increases exposure duration, emphasizing the need for immediate mitigations.

To mitigate CVE-2024-42788, organizations should implement the following specific measures: 1) Apply strict input validation on the 'title' and 'artist' parameters to reject or sanitize potentially malicious characters and scripts before storage. 2) Employ context-aware output encoding (e.g., HTML entity encoding) when rendering these fields in web pages to prevent script execution. 3) Use Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of any injected code. 4) Conduct thorough code reviews and security testing focusing on input handling in the affected endpoint. 5) If possible, isolate or restrict access to the vulnerable endpoint until a vendor patch is available. 6) Educate users about the risks of clicking untrusted links or content that may trigger stored XSS attacks. 7) Monitor web application logs for unusual input patterns or error messages indicative of exploitation attempts. 8) Engage with the vendor or community to obtain or develop patches and updates addressing this vulnerability. These steps go beyond generic advice by focusing on the specific parameters and endpoint involved.
