AI-suggested
European organizations should immediately upgrade KUNO CMS to version 1.3.14 or later to apply the official patch. Until the upgrade is performed, implement strict server-side validation of uploaded files beyond Content-Type headers, including: 1) Enforce a whitelist of allowed file extensions, explicitly excluding SVG or other potentially dangerous formats. 2) Perform content inspection of uploaded files to detect and block files containing embedded scripts or suspicious content. 3) Configure web application firewalls (WAFs) to detect and block malicious SVG payloads and suspicious upload patterns. 4) Limit file upload permissions to authenticated and authorized users only, if possible. 5) Implement Content Security Policy (CSP) headers to restrict execution of inline scripts and reduce the impact of XSS attacks. 6) Educate users about the risks of interacting with untrusted content and encourage cautious behavior. Regularly audit and monitor uploaded content for anomalies. These measures combined will reduce the attack surface and mitigate exploitation risk until the patch is applied.
Description
KUNO CMS is a fully deployable full-stack blog application. Versions 1.3.13 and below contain validation flaws in its file upload functionality that can be exploited for stored XSS. The upload endpoint only validates file types based on Content-Type headers, lacks file content analysis and extension whitelist restrictions, allowing attackers to upload SVG files containing malicious scripts (disguised as images). When users access the uploaded resource pages, arbitrary JavaScript executes in their browsers. This issue is fixed in version 1.3.14.
