CVE-2024-45967 identifies a Cross Site Scripting (XSS) vulnerability in Pagekit version 1.0.18, a PHP-based content management system. The vulnerability exists in the admin interface at the path index.php/admin/site/widget, where insufficient input sanitization allows attackers to inject malicious JavaScript code. This flaw is classified as CWE-79, indicating improper neutralization of input during web page generation. The vulnerability is remotely exploitable over the network without authentication, but requires user interaction, such as an administrator clicking a crafted link or visiting a malicious page. The CVSS 3.1 score of 4.7 reflects a medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component, and the impact is limited to integrity (I:L), with no confidentiality or availability impact. No patches or known exploits have been reported as of the publication date. The vulnerability could allow attackers to execute arbitrary scripts in the context of an admin user, potentially leading to session hijacking, unauthorized actions, or defacement. Given the administrative context, the impact is significant for the integrity of the CMS content and administrative control. Organizations using Pagekit 1.0.18 should assess exposure and implement mitigations promptly.

The primary impact of CVE-2024-45967 is on the integrity of the affected Pagekit CMS installations. Successful exploitation could allow attackers to execute arbitrary JavaScript in the administrator's browser session, potentially leading to session hijacking, unauthorized changes to site content, or injection of malicious content. While confidentiality and availability are not directly impacted, the integrity compromise can undermine trust in the affected websites and lead to further attacks such as phishing or malware distribution. Organizations relying on Pagekit 1.0.18 for website management may face reputational damage, loss of administrative control, and potential downstream impacts on users. Since the vulnerability requires user interaction, the risk is somewhat mitigated but remains significant in environments where administrators frequently access the vulnerable endpoint. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation. The vulnerability's medium severity suggests it should be addressed promptly to prevent escalation or chaining with other vulnerabilities.

To mitigate CVE-2024-45967, organizations should first verify if they are running Pagekit version 1.0.18 and restrict access to the admin interface, especially the index.php/admin/site/widget endpoint, to trusted networks and users. Implement strict input validation and output encoding on all user-supplied data in the affected endpoint to prevent script injection. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser context. Encourage administrators to avoid clicking on untrusted links and to use multi-factor authentication to reduce the impact of session hijacking. Monitor web server logs for suspicious requests targeting the vulnerable endpoint. Since no official patch is currently available, consider applying temporary workarounds such as disabling the vulnerable widget functionality or upgrading to a later Pagekit version if available. Stay alert for vendor updates or community patches addressing this vulnerability. Conduct regular security assessments and penetration testing focused on XSS vulnerabilities in administrative interfaces.
