CVE-2024-41613 is a Cross Site Scripting (XSS) vulnerability identified in Symphony CMS version 2.7.10. The vulnerability arises from insufficient input sanitization when users edit notes within the CMS, allowing remote attackers to inject arbitrary web scripts or HTML content. This injection can execute malicious scripts in the context of other users' browsers who view the affected notes, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The vulnerability requires no authentication (PR:N) but does require user interaction (UI:R), such as a user viewing the malicious note content. The attack vector is network-based (AV:N), and the vulnerability affects confidentiality and integrity with no impact on availability. The CVSS v3.1 base score is 6.1, indicating medium severity. The scope is changed (S:C) because the vulnerability affects resources beyond the vulnerable component. No official patches or fixes have been published yet, and no known exploits have been reported in the wild. The vulnerability is categorized under CWE-79, which relates to improper neutralization of input during web page generation. This flaw highlights the need for robust input validation and output encoding in web applications, especially CMS platforms that allow user-generated content.

The primary impact of CVE-2024-41613 is on the confidentiality and integrity of user data within affected Symphony CMS installations. Successful exploitation can lead to the execution of arbitrary scripts in users' browsers, enabling attackers to steal session cookies, perform unauthorized actions, or deface web content. This can undermine user trust and lead to data breaches or unauthorized access to sensitive information. While availability is not directly impacted, the reputational damage and potential regulatory consequences can be significant. Organizations relying on Symphony CMS for content management, especially those with public-facing websites or intranets, face increased risk of targeted attacks exploiting this vulnerability. The lack of authentication requirement lowers the barrier for attackers, increasing the likelihood of exploitation if the vulnerability is not mitigated promptly.

To mitigate CVE-2024-41613, organizations should implement strict input validation and output encoding on all user-supplied content, particularly in the note editing functionality of Symphony CMS. Employing Content Security Policy (CSP) headers can help restrict the execution of unauthorized scripts. Until an official patch is released, consider disabling or restricting note editing capabilities to trusted users only. Regularly monitor web application logs for suspicious input patterns indicative of XSS attempts. Employ web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting Symphony CMS. Educate users about the risks of interacting with untrusted content and encourage the use of updated browsers with built-in XSS protections. Finally, maintain an incident response plan to quickly address any exploitation attempts.
