CVE-2022-47928Network attack vector

Browser script execution via unescaped upload parameters

Published Dec 22, 2022 · Updated Aug 3, 2024

Reflected XSS in MISP before 2.4.167 allows remote attackers to execute JavaScript in a user's browser through a crafted template-upload URL. The app/View/Templates/upload_file.ctp view emits attacker-controlled element_id and result values into HTML and JavaScript contexts without escaping or safe encoding. Execution requires a user to open the malicious URL and click Upload File, after which the script runs with that user's browser-accessible MISP privileges.
